Proteins/UNIPROT:Q9NRW4
Dual specificity phosphatase; can dephosphorylate both phosphotyrosine and phosphoserine or phosphothreonine residues. Activates the JNK signaling pathway. Inhibits T-cell receptor signaling and T-cell mediated immune responses, acting, at least in part, by inducing degradation of E3 ubiquitin ligase UBR2. Dephosphorylates and thereby induces 'Lys-48'-linked ubiquitination of UBR2, leading to proteasomal degradation of UBR2. Dephosphorylates and thereby inactivates tyrosine kinase LCK. Inhibits UBR2-mediated 'Lys-63'-linked ubiquitination of LCK. May play a role in B-cell receptor (BCR) signaling and B-cell function (By similarity)..
