  ID: 1433S_HUMAN
DESCRIPTION: RecName: Full=14-3-3 protein sigma; AltName: Full=Epithelial cell marker protein 1; AltName: Full=Stratifin;
FUNCTION: Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. When bound to KRT17, regulates protein synthesis and epithelial cell growth by stimulating Akt/mTOR pathway (By similarity).
FUNCTION: p53-regulated inhibitor of G2/M progression.
SUBUNIT: Homodimer. Interacts with KRT17 and SAMSN1 (By similarity). Found in a complex with XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29, VPS35 and SFN. Interacts with GAB2. Interacts with SRPK2. Interacts with COPS6. Interacts with RFWD2; this interaction leads to proteasomal degradation.
INTERACTION: P00519:ABL1; NbExp=2; IntAct=EBI-476295, EBI-375543; Q7L5N1:COPS6; NbExp=7; IntAct=EBI-476295, EBI-486838; Q14103-4:HNRNPD; NbExp=7; IntAct=EBI-476295, EBI-432545; O00444:PLK4; NbExp=2; IntAct=EBI-476295, EBI-746202; Q8NHY2:RFWD2; NbExp=5; IntAct=EBI-476295, EBI-1176214;
SUBCELLULAR LOCATION: Cytoplasm. Nucleus (By similarity). Secreted. Note=May be secreted by a non-classical secretory pathway.
TISSUE SPECIFICITY: Present mainly in tissues enriched in stratified squamous keratinizing epithelium.
SIMILARITY: Belongs to the 14-3-3 family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
