Protein attributes
| Sequence length | 320 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 | Component of the asymmetric unit membrane (AUM); a highly specialized biomembrane elaborated by terminally differentiated urothelial cells. May play an important role in AUM-cytoskeleton interaction in terminally differentiated urothelial cells. It also contributes to the formation of urothelial glycocalyx which may play an important role in preventing bacterial adherence By similarity. |
| Subunit structure | Heterodimer with uroplakin-1B (UPK1B). |
| Subcellular location | Cell membrane; Single-pass type I membrane protein Potential. Note: Heterodimer formation with UPK1B is a prerequisite to exit out of the endoplasmic reticulum (ER). Ref.1 |
| Sequence similarities | Belongs to the uroplakin-3 family. |
| Sequence caution | The sequence AAO89507.1 differs from that shown. Reason: Frameshift at position 210. The sequence AAS07526.1 differs from that shown. Reason: Erroneous gene model prediction. |
