General annotation (Comments)
| Function | E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination, endocytosis and subsequent degradation of Wnt receptor complex components Frizzled. Acts on both canonical and non-canonical Wnt signaling pathway. Acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway, thereby resticting the size of the intestinal stem cell zone. Ref.6 Ref.8 Ref.9 |
| Pathway | |
| Subunit structure | Interacts with AKAP8L, NONO and SFPQ. Interacts with FZD5. Ref.6 Ref.7 Ref.9 |
| Subcellular location | Cell membrane; Single-pass type I membrane protein. Endoplasmic reticulum membrane; Single-pass type I membrane protein. Nucleus envelope. Note: According to a report, may be secreted (Ref.1). Ref.1 Ref.6 Ref.7 Ref.8 Ref.9 |
| Tissue specificity | Expressed in fetal kidney, fetal lung, in colon cancer tissues, hepatocellular carcinomas and lung adenocarcinomas. Overexpressed in colorectal cancer cell lines. Ref.1 Ref.6 |
| Post-translational modification | Autoubiquitinated. |
| Miscellaneous | Acts as a cytotoxic T-lymphocyte tumor antigen, suggesting that it may be used as a target for cancer immunotherapy (Ref.5). |
| Sequence similarities | Belongs to the ZNRF3 family. Contains 1 RING-type zinc finger. |
| Sequence caution | The sequence BAH12871.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
