PTPN4 Human

Source: E.coli.Sterile Filtered colorless solution.Protein Tyrosine Phosphatase Non Receptor Type-4, also known as PTPN4 belongs to the protein tyrosine phosphatase, PTP family. PTPs are identified as signaling molecules which regulate a variety of cellular processes as well as cell growth, differentiation, mitotic cycle, and oncogenic transformation. PTPN4 is broadly expressed non-receptor protein tyrosine phosphatase. In addition, PTPN4 interacts with glutamate receptor delta 2 & epsilon, and affects glutamate receptors signaling and/or in regulation of their activities through tyrosine dephosphorylation.PTPN4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 280 amino acids (655-913 a.a) and having a molecular mass of 32kDa. PTPN4 is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Protein function: Phosphatase that plays a role in immunity, learning, synaptic plasticity or cell homeostasis (PubMed:25825441, PubMed:27246854). Regulates neuronal cell homeostasis by protecting neurons against apoptosis (PubMed:20086240). Negatively regulates TLR4-induced interferon beta production by dephosphorylating adapter TICAM2 and inhibiting subsequent TRAM-TRIF interaction (PubMed:25825441). Dephosphorylates also the immunoreceptor tyrosine-based activation motifs/ITAMs of the TCR zeta subunit and thereby negatively regulates TCR-mediated signaling pathway. May act at junctions between the membrane and the cytoskeleton. [The UniProt Consortium]
