protein tyrosine phosphatase-like domain of tensin-3
Tensin-3 (TNS3) is also called tensin-like SH2 domain-containing protein 1 (TENS1) or tumor endothelial marker (TEM6). It is part of the tensin family of intracellular proteins (tensin-1, -2, -3 and -4), which act as links between the extracellular matrix and the cytoskeleton, and thereby mediate signaling for cell shape and motility. Tensin-3 contributes to cell migration, anchorage-independent growth, tumorigenesis, and metastasis of cancer cells. It cooperates with Dock5, an exchange factor for the small GTPase Rac, for osteoclast activity to ensure the correct organization of podosomes. Tensin-3 contains an N-terminal region with a protein tyrosine phosphatase (PTP)-like domain followed by a protein kinase 2 (C2) domain, and a C-terminal region with SH2 and pTyr binding (PTB) domains.
Feature 1: catalytic site [active site], 2 residue positions
Conserved feature residue pattern:C R
Evidence:
Comment:the catalytic cysteine initiates a nucleophilic attack on the phosphate group of the substrate, forming a transient phosphoenzyme intermediate and releasing the substrate dephosphorylated; the transition state is stabilized by the arginine present in the catalytic pocket
