Mouse Tyrosine-protein Phosphatase Non-receptor Type 4, PTPN4 ELISA Kit

Phosphatase that plays a role in immunity, learning, synaptic plasticity or cell homeostasis (PubMed: 17953619, PubMed: 25825441). Regulates neuronal cell homeostasis by protecting neurons against apoptosis (By similarity). 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 (PubMed: 18614237). May act at junctions between the membrane and the cytoskeleton.
