 4-88 2.23e-56

Stannin; Stannin (SNN) is a monotopic membrane protein containing an N-terminal single transmembrane helix that transverses the lipid bilayer, an unstructured linker which includes a conserved CXC metal-binding motif and a putative 14-3-3zeta binding site, and a C-terminal distorted cytoplasmic helix. It binds and antagonizes 14-3-3zeta and is required for endosomal maturation. It has also been identified as the specific marker for neuronal cell apoptosis induced by trimethyltin (TMT) intoxication. TMT is one of the most toxic organotin compound (or alkyltin), and is known to selectively inflict injury to specific regions of the brain.

Stannin transmembrane; Members of this family consist of a single highly hydrophobic transmembrane helix that transverses the lipid bilayer at a 20 degree angle with respect to the membrane normal. They contain a conserved cysteine residue (Cys32) that, together with Cys34 found in the stannin unstructured linker domain, constitutes the putative trimethyltin-binding site that resides at the end of the transmembrane domain close to the lipid/solvent interface.

 5-87 1.63e-47

Stannin family includes vertebrate Stannin and insect Hemotin; The Stannin family includes vertebrate Stannin and insect Hemotin, which are functional homologs required at the cellular level for endosomal maturation, and at the molecular level, to bind and antagonize 14-3-3zeta. Stannin is a monotopic membrane protein containing an N-terminal single transmembrane helix that transverses the lipid bilayer, an unstructured linker which includes a conserved CXC metal-binding motif and a putative 14-3-3zeta binding site, and a C-terminal distorted cytoplasmic helix. Analysis of the Hemotin sequence using a transmembrane topology prediction program revealed a very similar potential transmembrane alpha-helical domain arrangement as Stannin.

 34-59 3.40e-11

Stannin unstructured linker; Members of this family are unstructured, acting as connectors of the stannin helical domains. They contain a conserved CXC metal-binding motif and a putative 14-3-3-zeta binding domain. Upon coordinating dimethytin, considerable structural or dynamic changes in the flexible loop region of SNN may take place, recruiting other binding partners such as 14-3-3-zeta, and thereby initiating the apoptotic cascade.

Stannin cytoplasmic; Members of this family consist of a distorted cytoplasmic helix that is partially absorbed into the plane of the lipid bilayer with a tilt angle of approximately 80 degrees from the membrane normal. They interact with the surface of the lipid bilayer, and contribute to the initiation of the apoptotic cascade on binding of the unstructured linker domain to dimethyltin.
