ID:SNAI1_HUMAN DESCRIPTION: RecName: Full=Zinc finger protein SNAI1; AltName: Full=Protein snail homolog 1; Short=Protein sna; FUNCTION: Involved in the epithelial to mesenchymal transition (EMT) and formation and maintenance of embryonic mesoderm (By similarity). Binds to 3 E-boxes of the E-cadherin gene promoter and represses its transcription. SUBUNIT: Interacts with FBXL14 and GSK3B. Interacts with BTRC; interaction occurs when it is phosphorylated on the destruction motif. Interacts (via SNAG domain) with WTIP (via LIM domains) (By similarity). Interacts (via SNAG domain) with LIMD1 (via LIM domains), and AJUBA (via LIM domains). Interacts with LOXL2 and LOXL3. INTERACTION: P49841:GSK3B; NbExp=4; IntAct=EBI-1045459, EBI-373586; O60341:KDM1A; NbExp=4; IntAct=EBI-1045459, EBI-710124; P09874:PARP1; NbExp=10; IntAct=EBI-1045459, EBI-355676; SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Once phosphorylated (probably on Ser-107, Ser-111, Ser-115 and Ser-119) it is exported from the nucleus to the cytoplasm where subsequent phosphorylation of the destruction motif and ubiquitination involving BTRC occurs. TISSUE SPECIFICITY: Expressed in a variety of tissues with the highest expression in kidney. Expressed in mesenchymal and epithelial cell lines. PTM: Phosphorylated by GSK3B. Once phosphorylated, it becomes a target for BTRC ubiquitination. PTM: Ubiquitinated on Lys-98, Lys-137 and Lys-146 by FBXL14 and BTRC leading to degradation. BTRC-triggered ubiquitination requires previous GSK3B-mediated SNAI1 phosphorylation. PTM: O-GlcNAcylation at Ser-112 is enhanced in hyperglycaemic conditions, it opposes phosphorylation by GSK3B, and stabilizes the protein. SIMILARITY: Belongs to the snail C2H2-type zinc-finger protein family. SIMILARITY: Contains 4 C2H2-type zinc fingers.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
