 116-418 1.35e-157

M28 Zn-Peptidase Nicalin, Nicastrin-like protein; Peptidase M28 family, Nicalin (nicastrin-like protein) subfamily. Nicalin is distantly related to Nicastrin, a component of the Alzheimer's disease-associated gamma-secretase, and forms a complex with Nomo (nodal modulator) pM5. Similar to Nicastrin, Nicalin lacks the amino-acid conservation required for catalytically active aminopeptidases. Functional studies in zebrafish embryos and cultured human cells reveal that nicalin and Nomo collaborate to antagonize the Nodal/TGFbeta signaling pathway. Thus, nicastrin and nicalin are both associated with protein complexes involved in cell fate decisions during early embryonic development.

 190-414 6.77e-53

M28 Zn-peptidases include aminopeptidases and carboxypeptidases; Peptidase M28 family (also called aminopeptidase Y family) contains aminopeptidases as well as carboxypeptidases. They have co-catalytic zinc ions; each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. The aminopeptidases in this family are also called bacterial leucyl aminopeptidases, but are able to release a variety of N-terminal amino acids. IAP aminopeptidase and aminopeptidase Y preferentially release basic amino acids while glutamate carboxypeptidase II preferentially releases C-terminal glutamates. Plasma glutamate carboxypeptidase (PGCP) and glutamate carboxypeptidase II (NAALADase) hydrolyze dipeptides. Several members of the M28 peptidase family have PA domain inserts which may participate in substrate binding and/or in promoting conformational changes, which influence the stability and accessibility of the site to substrate. These include prostate-specific membrane antigen (PSMA), yeast aminopeptidase S (SGAP), human transferrin receptors (TfR1 and TfR2), plasma glutamate carboxypeptidase (PGCP) and several predicted aminopeptidases where relatively little is known about them. Also included in the M28 family are glutaminyl cyclases (QC), which are involved in N-terminal glutamine cyclization of many endocrine peptides. Nicastrin and nicalin belong to this family but lack the amino-acid conservation required for catalytically active aminopeptidases.

 190-333 1.05e-09

M28 Zn-peptidase Transferrin Receptor-like family; Peptidase M28 family; Transferrin Receptor (TfR) and prostate-specific membrane antigen (PSMA, also called glutamate carboxypeptidase or GCP-II) subfamily. TfR and PSMA are homodimeric type II transmembrane proteins containing three distinct domains: protease-like, apical or protease-associated (PA) and helical domains. The protease-like domain is a large extracellular portion (ectodomain). In TfR, it contains a binding site for the transferrin molecule and has 28% identity to membrane glutamate carboxypeptidase II (mGCP-II or PSMA). The PA domain is inserted between the first and second strands of the central beta sheet in the protease-like domain. TfR1 is widely expressed, and is a key player in the uptake of iron-loaded transferrin (Tf) into cells. The TfR1 homodimer binds two molecules of Tf and the complex is then internalized. TfR1 may also participate in cell growth and proliferation. TfR2 binds Tf but with a significantly lower affinity than TfR1. It is expressed chiefly in hepatocytes, hematopoietic cells, and duodenal crypt cells; its expression overlaps with that of hereditary hemochromatosis protein (HFE). TfR2 is involved in iron homeostasis; in humans, mutations in TfR2 are associated with a form of hemochromatosis (HFE3). PSMA is over-expressed predominantly in prostate cancer (PCa) as well as in the neovasculature of most solid tumors, but not in the vasculature of normal tissues. PSMA is considered a biomarker for PCa and possibly for use as an imaging and therapeutic target. The extracellular domain of PSMA possesses two unique enzymatic functions: N-acetylated, alpha-linked acidic dipeptidase (NAALADase) which cleaves terminal glutamate from the neurodipeptide N-acetyl-aspartyl-glutamate (NAAG), and folate hydrolase (FOLH) which cleaves the terminal glutamates from gamma-linked polyglutamates (carboxypeptidase). A mutation in this gene may be associated with impaired intestinal absorption of dietary folates, resulting in low blood folate levels and consequent hyperhomocysteinemia. Expression of this protein in the brain may be involved in a number of pathological conditions associated with glutamate excitotoxicity. This gene likely arose from a duplication event of a nearby chromosomal region. Alternative splicing gives rise to multiple transcript variants. While related in sequence to peptidase M28 GCP-II, TfR lacks the metal ion coordination centers and protease activity.

Nicastrin; Nicastrin and presenilin are two major components of the gamma-secretase complex, which executes the intramembrane proteolysis of type I integral membrane proteins such as the amyloid precursor protein (APP) and Notch. Nicastrin is synthesized in fibroblasts and neurons as an endoglycosidase-H-sensitive glycosylated precursor protein (immature nicastrin) and is then modified by complex glycosylation in the Golgi apparatus and by sialylation in the trans-Golgi network (mature nicastrin). A region featured in this family has a fold similar to human transferrin receptor (TfR) and a bacterial aminopeptidase. It is implicated in the pathogenesis of Alzheimer's disease.

 206-323 1.14e-05

M28 Zn-peptidase nicastrin, a main component of gamma-secretase complex; Peptidase M28 family, nicastrin subfamily. Nicastrin is a main component of the gamma-secretase complex, which also contains presenilin, Pen-2 and Aph-1. Its extracellular domain sequence resembles aminopeptidases, but certain catalytic residues are not conserved. It is mainly localized to the endoplasmic reticulum and Golgi. It is highly glycosylated (Mr 120 kDa) and is essential for substrate recognition of the N-terminus of gamma-secretase substrates derived from APP and Notch. Nicastrin facilitates substrate cleavage by the catalytic presenilin subunit in the gamma-secretase complex. One conserved glutamate is especially important, probably because this residue forms an ion pair with the amino terminus of the substrate. This substrate-binding domain is often called the DAP domain (named after DYIGS, the amino acid stretch that modulates amyloid precursor protein (APP) processing, and Peptidase homologous region). The sequence of the substrate N-terminus is apparently not critical for the interaction, but a free amino group is. Thus, nicastrin can be considered a kind of gatekeeper for the gamma-secretase complex: type I membrane proteins that have not shed their ectodomains cannot interact properly with nicastrin and do not gain access to the active site. Dysfunction of gamma-secretase is thought to cause Alzheimer's disease, with most mutations derived from Alzheimer's disease mapping to the catalytic subunit presenilin 1 (PS1).

 200-245 2.62e-05

M28 Zn-peptidase containing a protease-associated (PA) domain insert; Peptidase family M28 (also called aminopeptidase Y family), uncharacterized subfamily. The M28 family contains aminopeptidases as well as carboxypeptidases. They have co-catalytic zinc ions; each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. This subfamily is composed of uncharacterized proteins containing a protease-associated (PA) domain insert which may participate in substrate binding and/or promote conformational changes, influencing the stability and accessibility of the site to substrate.

M28 Zn-peptidase Aeromonas (Vibrio) proteolytica aminopeptidase; Peptidase family M28; Aeromonas (Vibrio) proteolytica aminopeptidase (AAP; leucine aminopeptidase from Vibrio proteolyticus; Bacterial leucyl aminopeptidase; E.C. 3.4.11.10) subfamily. AAP is a small (32kDa), heat stable leucine aminopeptidase and is active as a monomer. Similar forms of the enzyme have been isolated from Escherichia coli and Staphylococcus thermophilus. Leucine aminopeptidases, in general, play important roles in many biological processes such as protein catabolism, hormone degradation, regulation of migration and cell proliferation, as well as HIV infection and proliferation. AAP is a broad-specificity enzyme, utilizing two zinc(II) ions in its active site to remove N-terminal amino acids, with preference for large hydrophobic amino acids in the P1 position of the substrate, Leu being the most efficiently cleaved. It can accommodate all residues, except Pro, Asp and Glu in the P1' position.

 208-317 4.22e-04

M28 Zn-peptidase Transferrin Receptor family; Peptidase M28 family; Transferrin Receptor (TfR) subfamily. TfRs are homodimeric type II transmembrane proteins containing three distinct domains: protease-like, apical or protease-associated (PA), and helical domains. The protease-like domain is a large extracellular portion (ectodomain). In TfR, it contains a binding site for the transferrin molecule and has 28% identity to membrane glutamate carboxypeptidase II (mGCP-II or PSMA). The PA domain is inserted between the first and second strands of the central beta sheet in the protease-like domain. TfR1 is widely expressed, and is a key player in the uptake of iron-loaded transferrin (Tf) into cells. The TfR1 homodimer binds two molecules of Tf and the complex is then internalized. TfR1 may also participate in cell growth and proliferation. TfR2 binds Tf but with a significantly lower affinity than TfR1. It is expressed chiefly in hepatocytes, hematopoietic cells, and duodenal crypt cells; its expression overlaps with that of hereditary hemochromatosis protein (HFE). TfR2 is involved in iron homeostasis; in humans, mutations in TfR2 are associated with a form of hemochromatosis (HFE3). While related in sequence to peptidase M28 glutamate carboxypeptidase II (also called prostate-specific membrane antigen or PSMA), TfR lacks the metal ion coordination centers and protease activity of that group.

M28 Zn-peptidase Endoplasmic reticulum metallopeptidase 1; Peptidase family M28; Endoplasmic reticulum metallopeptidase 1 (ERMP1; Felix-ina, FXNA or Fxna peptidase; KIAA1815) subfamily. ERMP1 is a multi-pass membrane protein located in the endoplasmic reticulum membrane. In humans, Fxna may play a crucial role in processing proteins required for the organization of somatic cells and oocytes into discrete follicular structures, although which proteins are hydrolyzed has not yet been determined. Another member of this subfamily is the 24-kDa vacuolar protein (VP24) which is probably involved in the formation of intravacuolar pigmented globules (cyanoplasts) in highly anthocyanin-containing vacuoles; however, the biological function of the C-terminal region which includes the putative transmembrane metallopeptidase domain is unknown.
