NME2 Antibody / NM23-H2

NME2 (NME/NM23 nucleoside diphosphate kinase 2) also called non-metastatic cells 2, protein (NM23B) expressed in, NM23-H2, NM23B or NDPKB, is identical to the beta subunit of human erythrocyte NDP kinase. Using Northern blot analysis, Masse et al. (2002) detected high expression of mouse NME2, which they called nm23-M2, in heart, liver, and kidney, with intermediate expression in skeletal muscle. In situ hybridization of 15-day postcoitum mouse embryos showed ubiquitous expression. The mouse and human genes contain 5 exons and span about 6.0 kb. The NME2 gene is mapped on 17q21.33. Srivastava et al. (2006) concluded that histidine phosphorylation regulates KCa3.1 channel activity and that NME2 is critical to the channel activity and the activation of CD4 T cells.
