Chromosomal localization of an SH2-containing tyrosine phosphatase (PTPN6)

Genomics. 1992 Jul;13(3):869-72. doi: 10.1016/0888-7543(92)90172-o.


We have used panels of somatic cell hybrids and fluorescent in situ hybridization to determine the chromosomal localization of the novel nontransmembrane tyrosine phosphatase PTPN6 (protein tyrosine phosphatase, nonreceptor type 6), which contains two SH2 domains. PTPN6 maps to 12p13, a region commonly involved in leukemia-associated chromosomal abnormalities. Since PTPN6 is expressed at high levels in hematopoietic cells of all lineages and its expression is induced early in hematopoietic differentiation, altered expression and/or structure of PTPN6 may play a role in leukemogenesis.
