Human Gene MUC17 (ENST00000306151.9) Description and Page Index
  Description: Homo sapiens mucin 17, cell surface associated (MUC17), transcript variant 1, mRNA. (from RefSeq NM_001040105)
RefSeq Summary (NM_001040105): The protein encoded by this gene is a membrane-bound mucin that provides protection to gut epithelial cells. The encoded protein contains about 60 tandem repeats, with each repeat being around 60 aa. N-glycosylation enables the encoded protein to localize on the cell surface, while the C-terminus interacts with the scaffold protein PDZ domain containing 1 (PDZK1). Two transcript variants, one protein-coding and the other non-protein coding, have been found for this gene. [provided by RefSeq, Nov 2015].

DESCRIPTION: RecName: Full=Mucin-17; Short=MUC-17; AltName: Full=Small intestinal mucin-3; Short=MUC-3; Flags: Precursor;
FUNCTION: Probably plays a role in maintaining homeostasis on mucosal surfaces.
SUBUNIT: Interacts via its C-terminus with PDZK1 and this interaction appears important for proper localization.
SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Single-pass membrane protein.
SUBCELLULAR LOCATION: Isoform 2: Secreted (Probable). Cell membrane.
TISSUE SPECIFICITY: Expressed almost exclusively in the intestine. Expression is especially high in both the duodenum and transverse colon. Expressed in mature absorptive cells of the small intestinal villi. No expression is detected in goblet cells. Highly expressed in pancreatic adenocarcinoma tissue (at protein level). Expression is not detectable in normal pancreas, in pancreatitis or in cell lines derived from other cancers.
PTM: Probably cleaved within the SEA domain.
PTM: N-glycosylated. Contains high mannose and complex-type glycans. The forms containing the complex type glycans localize to the cell surface. Not O-glycosylated.
SIMILARITY: Contains 1 EGF-like domain.
SIMILARITY: Contains 1 SEA domain.

ModBase Predicted Comparative 3D Structure on Q685J3
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.
