General annotation (Comments)
| Function | May be involved in the regulation of specific developmental processes in the CNS. Phosphacan, previously designated 3F8 chondroitin sulfate proteoglycan or 3H1 keratan sulfate proteoglycan depending on the glycosylation status, is a soluble nervous tissue-specific proteoglycan. It is synthesized by glia and binds to neurons and to the neural cell adhesion molecules tenascin, N-CAM or NG-CAM but not to laminin and fibronectin. Phosphacan acts as a potent inhibitor of cell adhesion and neurite outgrowth. |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Subunit structure | The carbonic-anhydrase like domain binds to contactin. |
| Subcellular location | |
| Tissue specificity | Nervous tissue specific. |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Receptor class 5 subfamily. Contains 1 alpha-carbonic anhydrase domain. Contains 1 fibronectin type-III domain. Contains 2 tyrosine-protein phosphatase domains. |
