– 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. PTPRZ1 Protein, Human, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 32.1 kDa and the accession number is P23471.
