CD22 is a B cell membrane glycoprotein that, upon Ag receptor engagement, becomes rapidly tyrosyl phosphorylated and associates with several signaling molecules including Lyn, Syk, PLCgamma1, and the protein-tyrosine phosphatase, SHP-1. Two allelic f

Interferons (IFNs) induce early-response genes by stimulating Janus family (Jak) tyrosine kinases, leading to tyrosine phosphorylation of Stat transcription factors. Previous studies implicated protein-tyrosine phosphatase (PTP) activity in the contr

The cytoplasmic insulin receptor substrate-1 (IRS-1), which is multiply phosphorylated in vivo on tyrosine residues, is a known binding protein for the tandem src homology 2 (SH2) domain-containing protein tyrosine phosphatase, SH-PTP2. Eleven phosph

Signaling by tyrosine kinases involves direct associations between proteins with Src homology 2 (SH2) domains and sites of tyrosine phosphorylation. Specificity in signaling pathways results in part from inherent selectivity in interactions between p

PTP-1B is a major nontransmembrane phosphotyrosine phosphatase in human cell lines and tissues, but its physiological function(s) and mechanism(s) of regulation are largely unknown. We have found that in human diploid fibroblasts a novel PTP-1B mRNA

A human protein tyrosine phosphatase containing two src homology 2 (SH2) domains (SH-PTP2) was expressed in Escherichia coli under T7 promoter control and purified to near homogeneity. The purified protein, with molecular mass of 68 kDa on SDS-polyac

Much progress has been made in elucidating early events in signal transduction by growth factor receptors with intrinsic tyrosine kinase activity. Upon ligand addition, these receptors dimerize and activate, becoming phosphorylated at a number of tyr

The pivotal role of tyrosine kinases in signal transduction is well established, but the role of tyrosine phosphatases remains obscure. The discovery of src homology 2 domain-containing protein tyrosine phosphatases suggested roles for these molecule

One of the three human retinoic acid receptors, RAR-beta, maps to a region on the short arm of chromosome 3 frequently deleted in lung cancer. Because retinoic acid is required for normal epithelial cell growth and regulation, and loss of a retinoic
