RECEPTOR PROTEIN TYROSINE PHOSPHATASE ALPHA, DOMAIN 1 FROM MOUSE
Overview
Receptor-like protein-tyrosine phosphatases (RPTPs), like their, non-receptor counterparts, regulate the level of, phosphotyrosine-containing proteins derived from the action of, protein-tyrosine kinases. RPTPs are type-I integral membrane proteins, which contain one or two catalytic domains in their cytoplasmic region. It, is not known whether extracellular ligands regulate the activity of RPTPs., Here we describe the crystal structure of the membrane-proximal catalytic, domain (D1) of a typical RPTP, murine RPTP alpha. Significant structural, deviations from the PTP1B fold reside within the amino-terminal, helix-turn-helix segment of RPTPalphaD1 (residues 214 to 242) and a, distinctive two-stranded beta-sheet formed between residues 211-213 and, 458-461. The turn of the N-terminal ... [(full description)]
