Protein attributes
| Sequence length | 1446 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 | Tyrosine-protein phosphatase which dephosphorylates CTNNB1. Regulates CTNNB1 function both in cell adhesion and signaling. May function in cell proliferation and migration and play a role in the maintenance of epithelial integrity. May play a role in megakaryocytopoiesis By similarity. |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Subunit structure | Forms homooligomeric complexes which mediate cell homotypic adhesion Probable. Interacts (via the cytoplasmic juxtamembrane domain) with CTNNB1; may mediate interaction with the cadherin/catenin adhesion complex. Interacts with KIT By similarity. May interact with AP3B1 By similarity. Ref.2 |
| Subcellular location | Cell junction By similarity. Cell membrane; Single-pass type I membrane protein By similarity. |
| Tissue specificity | Transcripts of different sizes are differentially expressed in a subset of tissues. Detected in brain, lung, skeletal muscle, heart, kidney and placenta. In brain; expressed in olfactory bulb, cerebral cortex, hippocampus and cerebellum. Ref.1 Ref.2 Ref.7 |
| Developmental stage | Expressed throughout embryonic development. First detected at E7. Ref.2 |
| Post-translational modification | The extracellular domain is proteolytically processed through cleavage within the fibronectin type-III 4 domain. Beside the 190 kDa full-length protein, proteolytic products of 100 kDa, 80 kDa and 73 kDa are observed By similarity. N-glycosylated By similarity. Phosphorylated on tyrosine residues upon activation of KIT with stem cell factor (SCF). The 73 kDa proteolytic product is not phosphorylated By similarity. |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Receptor class 2B subfamily. Contains 4 fibronectin type-III domains. Contains 1 Ig-like C2-type (immunoglobulin-like) domain. Contains 1 MAM domain. Contains 2 tyrosine-protein phosphatase domains. |
| Sequence caution | The sequence AAH80736.1 differs from that shown. Reason: Erroneous termination at position 618. Translated as Arg. The sequence AAH80736.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence BAE43351.1 differs from that shown. Reason: Intron retention. |
