Previous GeneCards Identifiers for PTPN4 Gene
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.

GeneCards Summary for PTPN4 Gene
PTPN4 (Protein Tyrosine Phosphatase Non-Receptor Type 4) is a Protein Coding gene. Diseases associated with PTPN4 include Rabies. Among its related pathways are Innate Immune System and Activated TLR4 signalling. Gene Ontology (GO) annotations related to this gene include phosphatase activity and cytoskeletal protein binding. An important paralog of this gene is PTPN3.
UniProtKB/Swiss-Prot Summary for PTPN4 Gene
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 (By similarity). May act at junctions between the membrane and the cytoskeleton.
