Protein: Receptor-type tyrosine-protein phosphatase zeta (R-PTP-zeta) (EC 3.1.3.48) (3F8 chondroitin sulfate proteoglycan) (3H1 keratan sulfate proteoglycan) (Phosphacan) (Q62656)
Organism: Rattus norvegicus (Rat)
Function: Protein tyrosine phosphatase that negatively regulates oligodendrocyte precursor proliferation in the embryonic spinal cord. Required for normal differentiation of the precursor cells into mature, fully myelinating oligodendrocytes. May play a role in protecting oligondendrocytes against apoptosis. May play a role in the establishment of contextual memory, probably via the dephosphorylation of proteins that are part of important signaling cascades (By similarity).
Subcellular location: [Isoform 1]: Cell membrane {ECO:0000269|PubMed:16814777}; Single-pass type I membrane protein {ECO:0000269|PubMed:16814777}. Secreted {ECO:0000250}. Note=A secreted form is apparently generated by shedding of the extracellular domain. {ECO:0000250}.; SUBCELLULAR LOCATION: [Isoform 2]: Secreted {ECO:0000305}.; SUBCELLULAR LOCATION: [Isoform 3]: Secreted.
