Detection of Human, Mouse, and Rat NM23‑H1/H2 by Western Blot. Western blot shows lysates of A431 human epithelial carcinoma cell line, HepG2 human hepatocellular carcinoma cell line, HT-2 mouse T cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF Membrane was probed with 0.5 µg/mL of Mouse Anti-Human/Mouse/Rat NM23-H1/H2 Monoclonal Antibody (Catalog # MAB6019) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human NM23-H1 and recombinant human NM23-H2 (10 ng/lane) were included. Specific bands were detected for NM23-H1/H2 at approximately 17-20 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: NM23-H1/H2

NM23-H1 (Non-metastatic protein 23 homolog 1; also NDKA and NME1) is a 19‑20 kDa member of the NDK family of enzymes. NM23-H1 is ubiquitous in expression, and performs multiple functions. It forms disulfide-linked homohexamers, and heterohexamers with NM23-H2, generating a nucleoside diphosphate kinase that catalyzes a phosphoryl transfer from ATP to a nucleoside diphosphate. It also shows His and Ser/Thr protein kinase activity, and forms covalent linkages with molecules diverse as p53 and STRAP. It is found both intracellularly, and in blood at ng/mL concentrations. Human NM23-H1 is 152 amino acids (aa) in length, contains one NDP kinase domain (aa 5‑134) and shows acetylation at Ala2 and Lys56, plus phosphorylation at Tyr52, Thr94, Ser122 and Ser125. Human NM23-H1 shares 89% aa identity with human 17‑18 kDa NM23-H2, and 94% aa identity with mouse NM23-H1. A second H1 isoform named NM23-H1B with 25 additional aa at the N‑terminus has also been described.
