Tyrosine phosphatase
From Proteopedia
Tyrosine phosphatase (PTP) is an enzyme which removes phosphate from phosphorylated tyrosine residues. It is a key regulatory component of signal transduction pathways. PTPs are divided to 4 subfamilies. PTP class I contains receptor PTPs (RPTP) and dual-specificity PTP which removes phosphate from Ser/Thr and tyrosine. PTP class III contains CDC25 which removes phosphate from Thr and tyrosine. PTP containing SH2 domains are called PTP SHP.
