By screening a human fetal liver cDNA library with a PTP-gamma (PTPRG; 176886) probe, Krueger et al. (1990) cloned a partial cDNA for PTPRE, which they called PTP-epsilon. The deduced protein has a transmembrane segment and a cytoplasmic region containing duplicated PTPase domains.
Elson et al. (1996) noted that 2 isoforms of PTP-epsilon, a transmembrane, receptor-type isoform and a shorter, cytoplasmic isoform, appear to arise through the use of alternative promoters and 5-prime exons.
High levels of PTPase-epsilon transcription were noted in mouse brain and testis by Yi et al. (1991).
Van den Maagdenberg et al. (1995) isolated cosmids containing sequences for PTPRE and used these to map the gene to chromosome 10q26 by fluorescence in situ hybridization. Melhado et al. (1996) likewise showed that the PTPRE gene is located on 10q26 by isotopic in situ hybridization. Elson et al. (1996) also mapped the PTPRE gene to chromosome 10q26 by FISH.
Watanabe et al. (1995) mapped the mouse Ptpre gene to within the vicinity of the imprinted region in the distal part of chromosome 7. Elson et al. (1996) also mapped the mouse Ptpre gene to distal chromosome 7.
