Protein attributes
| Sequence length | 4493 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Probably plays a role in maintaining homeostasis on mucosal surfaces. Ref.6 |
| Subunit structure | Interacts via its C-terminus with PDZK1 and this interaction appears important for proper localization. Ref.6 |
| Subcellular location | Isoform 1: Cell membrane; Single-pass membrane protein Ref.5. Isoform 2: Secreted Probable. Cell membrane Ref.5. |
| 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. Ref.1 Ref.3 Ref.4 |
| Post-translational modification | Probably cleaved within the SEA domain. N-glycosylated. Contains high mannose and complex-type glycans. The forms containing the complex type glycans localize to the cell surface. Not O-glycosylated. Ref.5 |
| Sequence similarities | Contains 1 EGF-like domain. Contains 1 SEA domain. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q685J3-1) Also known as: Major; Mb-MUC17; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q685J3-2) Also known as: Minor; s-MUC17; The sequence of this isoform differs from the canonical sequence as follows: 4241-4262: RLGSVVVEHDVLLRTKYTPEYK → HDVFQHHWHPSAKHYGDPVRP 4363-4493: Missing. |
