 22-138 3.24e-85

ANTH (AP180 N-Terminal Homology) domain, N-terminal region, of adaptor protein 180 (AP180) subfamily; The Adaptor Protein 180 (AP180) subfamily members are phosphatidylinositol-binding clathrin assembly proteins, including mammalian clathrin coat assembly protein AP180 and Clathrin Assembly Lymphoid Myeloid Leukemia protein (CALM), Drosophila LAP (also called Like-AP180 or AP180), and Caenorhabditis elegans Uncoordinated protein 11 (unc-11, also called AP180-like adaptor protein). They are components of the adaptor complexes which link clathrin to receptors in coated vesicles. AP180 and CALM play important roles in clathrin-mediated endocytosis. AP180, also called 91 kDa synaptosomal-associated protein (SNAP91) or phosphoprotein F1-20, is a brain-specific clathrin-binding protein which stimulates clathrin assembly during the recycling of synaptic vesicles. CALM, also called phosphatidylinositol binding clathrin assembly protein (PICALM), is ubiquitously expressed. Members of this subfamily contain ANTH domains, which bind both inositol phospholipids and proteins, and contribute to the nucleation and formation of clathrin coats on membranes. The ANTH domain is a unique module whose N-terminal half is structurally similar to the Epsin N-Terminal Homology (ENTH) and Vps27/Hrs/STAM (VHS) domains, containing a superhelix of eight alpha helices. In addition, it contains a coiled-coil C-terminal half with strutural similarity to spectrin repeats. It binds phosphoinositide PtdIns(4,5)P2 at a short conserved motif K[X]9[K/R][H/Y] between helices 1 and 2. This model describes the N-terminal region of ANTH domains of the Adaptor Protein 180 (AP180) subfamily.

 22-137 7.14e-42

VHS, ENTH and ANTH domain superfamily; This superfamily is composed of proteins containing a VHS, CID, ENTH, or ANTH domain. The VHS domain is present in Vps27 (Vacuolar Protein Sorting), Hrs (Hepatocyte growth factor-regulated tyrosine kinase substrate) and STAM (Signal Transducing Adaptor Molecule). It is located at the N-termini of proteins involved in intracellular membrane trafficking. The CTD-Interacting Domain (CID) is present in several RNA-processing factors and binds tightly to the carboxy-terminal domain (CTD) of RNA polymerase II (RNAP II or Pol II). The epsin N-terminal homology (ENTH) domain is an evolutionarily conserved protein module found primarily in proteins that participate in clathrin-mediated endocytosis. A set of proteins previously designated as harboring an ENTH domain in fact contains a highly similar, yet unique module referred to as an AP180 N-Terminal Homology (ANTH) domain. VHS, ENTH, and ANTH domains are structurally similar and are composed of a superhelix of eight alpha helices. ENTH and ANTH (E/ANTH) domains bind both inositol phospholipids and proteins and contribute to the nucleation and formation of clathrin coats on membranes. ENTH domains also function in the development of membrane curvature through lipid remodeling during the formation of clathrin-coated vesicles. E/ANTH domain-bearing proteins have recently been shown to function with adaptor protein-1 and GGA adaptors at the Trans-Golgi Network, which suggests that E/ANTH domains are universal components of the machinery for clathrin-mediated membrane budding.

ANTH (AP180 N-Terminal Homology) domain, N-terminal region, of yeast clathrin coat assembly protein AP180 (YAP180) and similar proteins; This subfamily includes yeast clathrin coat assembly protein AP180 (YAP180) and similar proteins. There are two YAP180 proteins in Saccharomyces cerevisiae, AP180A (yAP180A or YAP1801) and AP180B (yAP180B or YAP1802). They are involved in endocytosis and clathrin cage assembly. ANTH domains bind both inositol phospholipids and proteins, and contribute to the nucleation and formation of clathrin coats on membranes. The ANTH domain is a unique module whose N-terminal half is structurally similar to the Epsin N-Terminal Homology (ENTH) and Vps27/Hrs/STAM (VHS) domains, containing a superhelix of eight alpha helices. In addition, it contains a coiled-coil C-terminal half with strutural similarity to spectrin repeats. It binds phosphoinositide PtdIns(4,5)P2 at a short conserved motif K[X]9[K/R][H/Y] between helices 1 and 2. This model describes the N-terminal region of ANTH domains of plant clathrin coat assembly protein AP180 and similar proteins.

ANTH (AP180 N-Terminal Homology) domain, N-terminal region, of plant Clathrin coat assembly protein AP180 and similar proteins; This subfamily is composed of plant clathrin coat assembly protein AP180 and other ANTH domain containing proteins that are yet to be characterized. Arabidopsis thaliana AP180 (At-AP180) is a binding partner of plant alphaC-adaptin; it functions as a clathrin assembly protein that promotes the formation of cages with an almost uniform size distribution. In addition to At-AP180, Arabidopsis thaliana contains many ANTH domain containing proteins labelled as putative clathrin assembly proteins included in this subfamily such as At4g02650, At5g10410, At2g25430, and At1g33340, among others. ANTH domains bind both inositol phospholipids and proteins, and contribute to the nucleation and formation of clathrin coats on membranes. The ANTH domain is a unique module whose N-terminal half is structurally similar to the Epsin N-Terminal Homology (ENTH) and Vps27/Hrs/STAM (VHS) domains, containing a superhelix of eight alpha helices.

 22-136 1.83e-07

ANTH (AP180 N-Terminal Homology) domain, N-terminal region, of Sla2p/HIP1/HIP1R subfamily; Members of the Sla2p/HIP1/HIP1R subfamily share a common domain architecture, containing an N-terminal ANTH, a central clathrin-binding colied-coil, and a C-terminal actin-binding talin-like (also called I/LWEQ) domains. HIP1 was identified in 1997 as an interactor of huntingtin; when mutated, it is involved in the neurodegenerative disorder Huntington's disease. Both HIP1 and HIP1R promote clathrin assembly in vitro. Yeast Sla2p, is a regulator of membrane cytoskeleton assembly. ANTH domains bind both inositol phospholipids and proteins, and contribute to the nucleation and formation of clathrin coats on membranes. The ANTH domain is a unique module whose N-terminal half is structurally similar to the Epsin N-Terminal Homology (ENTH) and Vps27/Hrs/STAM (VHS) domains, containing a superhelix of eight alpha helices. In addition, it contains a coiled-coil C-terminal half with strutural similarity to spectrin repeats. It binds phosphoinositide PtdIns(4,5)P2 at a short conserved motif K[X]9[K/R][H/Y] between helices 1 and 2. While the ANTH domain of Sla2p preferentially binds PtdIns(4,5)P2, which is considered to be an interaction hub in the clathrin interactome, mammalian HIP1 and HIP1R were found to preferentially bind PtdIns(3,4)P2 and PtdIns(3,5)P2, respectively. This model describes the N-terminal region of ANTH domains of the Sla2p/HIP1/HIP1R subfamily.

ANTH (AP180 N-Terminal Homology) domain, N-terminal region, of Sla2p and similar proteins; This subfamily is composed of Saccharomyces cerevisiae Sla2 protein (Sla2p, also called transmembrane protein MOP2), Schizosaccharomyces pombe endocytosis protein End4 (End4p, also called Sla2 protein homolog), and similar proteins. In yeast, cells lacking Sla2p have severe defects in actin organization, cell morphology, and endocytosis, suggesting roles in these processes. Sla2p regulates the Eps15-like Arp2/3 complex activator, Pan1p, controlling actin polymerization during endocytosis. In fission yeast, End4p has been implicated in cellular morphogenesis. Sla2p contains an N-terminal ANTH, a central colied-coil, and a C-terminal actin-binding talin-like (also called I/LWEQ) domains. ANTH domains bind both inositol phospholipids and proteins, and contribute to the nucleation and formation of clathrin coats on membranes. The ANTH domain is a unique module whose N-terminal half is structurally similar to the Epsin N-Terminal Homology (ENTH) and Vps27/Hrs/STAM (VHS) domains, containing a superhelix of eight alpha helices.

This model describes the N-terminal region of ANTH domains f Sla2p and similar proteins.

Epsin N-Terminal Homology (ENTH) domain family; The Epsin N-Terminal Homology (ENTH) domain is an evolutionarily conserved protein module found primarily in proteins that participate in clathrin-mediated endocytosis. ENTH domain is highly similar to the N-terminal region of the AP180 N-Terminal Homology (ANTH_N) domain. ENTH and ANTH_N domains are structurally similar to the VHS domain and are composed of a superhelix of eight alpha helices. ENTH domains bind both, inositol phospholipids with preference for PtdIns(4,5)P2, and proteins, contributing to the nucleation and formation of clathrin coats on membranes. ENTH domains also function in the development of membrane curvature through lipid remodeling during the formation of clathrin-coated vesicles. ENTH and ANTH (E/ANTH)-containing proteins have recently been shown to function with adaptor protein-1 and GGA adaptors at the Trans-Golgi Network, which suggests that E/ANTH domains are universal components of the machinery for clathrin-mediated membrane budding.
