The Nonreceptor Protein Tyrosine Phosphatase PTP1B Binds to the Cytoplasmic Domain of N-Cadherin and Regulates the Cadherin–Actin Linkage
Cadherin-mediated adhesion depends on the association of its cytoplasmic domain with the actin-containing cytoskeleton. This interaction is mediated by a group of cytoplasmic proteins: alpha-and beta- or gamma- catenin. Phosphorylation of beta-catenin on tyrosine residues plays a role in controlling this association and, therefore, cadherin function. Previous work from our laboratory suggested ...
متن کاملThe Protein Tyrosine Phosphatase PTP1B Is Required for Efficient Delivery of N-Cadherin to the Cell Surface
PTP1B bound to mature N-cadherin promotes the association of beta-catenin into the complex, the stable expression of the complex at cell surface, and cadherin-mediated adhesion. Here we show that PTP1B is also required for N-cadherin precursor trafficking through early stages of the secretory pathway. This function does not require association of PTP1B with the precursor. In PTP1B null cells, t...

TC-PTP is a ubiquitous non-receptor type protein tyrosine phosphatase that shows highest expression in hematopoietic tissues. It regulates many signal transduction pathways in hematopoietic as well as non-hematopoietic cells. TCPTP has two splice variants, an endoplasmic reticulum-localized TC48, and predominantly nuclear TC45. Upon various stress conditions and insulin stimuli, TC45 comes out ...
