Description
The protein encoded by the PTPN4 gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This protein contains a C-terminal PTP domain and an N-terminal domain homologous to the band 4.1 superfamily of cytoskeletal-associated proteins. This PTP has been shown to interact with glutamate receptor delta 2 and epsilon subunits, and is thought to play a role in signalling downstream of the glutamate receptors through tyrosine dephosphorylation.

Predicted to enable protein tyrosine phosphatase activity. Predicted to be involved in protein dephosphorylation. Predicted to act upstream of or within peptidyl-tyrosine phosphorylation. Located in cytoplasm and cytoplasmic side of plasma membrane.

3 Proteins

3.1 Protein Function

Phosphatase that plays a role in immunity, learning, synaptic plasticity or cell homeostasis (PMID: 25825441, PMID: 27246854). Regulates neuronal cell homeostasis by protecting neurons against apoptosis (PMID: 20086240). Negatively regulates TLR4-induced interferon beta production by dephosphorylating adapter TICAM2 and inhibiting subsequent TRAM-TRIF interaction (PMID: 25825441). Dephosphorylates also the immunoreceptor tyrosine-based activation motifs/ITAMs of the TCR zeta subunit and thereby negatively regulates TCR-mediated signaling pathway (By similarity). May act at junctions between the membrane and the cytoskeleton.
