Regional localization of rat and mouse protein-tyrosine phosphatase PTPα/LRP gene (Ptpra) by fluorescence in situ hybridization

抄録

Protein tyrosine phosphatases (PTPases) negatively regulae the effect(s) of protein tyrosine kinases and are implicated in the regulation of a variety of biological events including cell activation, differentiation, and neoplastic transformation. To gain insight into the role(s) of the PTPases, we mapped the gene encoding for the widely expressed receptor-like protein tyrosine phosphatase PTPα/LRP (locus symbol Ptpra) to rat chromosome 3q36 and mouse chromosome 2G by fluorescence in situ hybridization method. These results indicate that there is a conserved syntenic group between human 20p13, rat 3q36, and mouse 2G.
