| Post Translational Modifications | Highly phosphorylated on serine and threonine residues but not on tyrosines. Cleaved and activated by calpain I/CAPN1. |
| 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. Also dephosphorylates 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. |
