Target Name
PTPN4
Target Full Name
Tyrosine-protein phosphatase non-receptor type 4
Target Function
Phosphatase that plays a role in immunity, learning, synaptic plasticity or cell homeostasis. Regulates neuronal cell homeostasis by protecting neurons against apoptosis. Negatively regulates TLR4-induced interferon beta production by dephosphorylating adapter TICAM2 and inhibiting subsequent TRAM-TRIF interaction. 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.
Target Subcellular Location
Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasm, cytoskeleton. Cytoplasm.
Target Protein Families
Protein-tyrosine phosphatase family, Non-receptor class subfamily

Target Background
The protein encoded by this 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.
