Abstract

It is now widely accepted that protein tyrosine phosphatases (PTPases) play important or even critical roles in cell growth, differentiation, and development. Our recent experiments suggested that specific PTPases, PTPβ2 and PTPε, are involved in the early molecular events forin vitrodifferentiation of mouse erythroleukemia (MEL) as well as embryonic carcinoma (F9) cells. Using mouse cDNA for PTPβ2 and PTPε, which we have cloned recently, we attempted to locate the genes to mouse chromosomes. Interspecific backcross analysis indicated that the gene for PTPβ2, Ptprj, is located in the middle region of chromosome 2, and the gene for PTPε, Ptpre, was mapped in the vicinity of the imprinted regions in the distal part of chromosome 7. Possible biological roles of these PTPases are discussed.
