Scientific Data Images for Human/Mouse/Rat PKM1/2 Antibody

Detection of Human, Mouse, and Rat PKM2 antibody by Western Blot.

Detection of Human, Mouse, and Rat PKM2 by Western Blot.

Western blot shows lysates of A549 human lung carcinoma cell line, BaF3 mouse pro-B 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 PKM1/2 Monoclonal Antibody (Catalog # MAB72442) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for PKM2 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human PKM2 by Western Blot.

Western blot shows lysates of U-87 MG human glioblastoma/astrocytoma cell line, A549 human lung carcinoma cell line, HeLa human cervical epithelial carcinoma cell line, human skeletal muscle. PVDF membrane was probed with 0.25 µg/mL of Mouse Anti-Human/Mouse/Rat PKM2 Monoclonal Antibody (Catalog # MAB72442) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for PKM2 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: PKM2

PKM2 (Pyruvate Kinase isoenzyme M2; also p58, OIP3, THBP1 and CTHBP) is a 58-60 kDa member of the PK family of enzymes. It is widely expressed, being found both intracellularly and in blood, and represents the more common splice variant of the PKM gene. PKM2 generates ATP and pyruvate by catalyzing the transfer of a phosphoryl group from PEP to ADP. Thus, when active, PKM2 promotes energy production and glycolysis. PKM2 exists as a marginally active monomer, with full activity achieved through homotetramerization. Notably, in tumor cells, select oncogenes appear to induce PKM2 homodimerization which limits PKM2 activity. PKM2 is known to be regulated by the binding of T3 and Fru-1,6-bisP. Human PKM2 is 531 amino acids (aa) in length. It contains a catalytic region (aa 43‑527) plus four utilized Ser/Thr and Tyr phosphorylation sites, respectively. PKM1 is another PKM gene splice variant that shows a 45 aa substitution for aa 389‑433 of PKM2. This variant shows limited expression (striated muscle) and hyperbolic Michaelis-Menten kinetics. There are additional isoform variants of PKM2 that show either a deletion of aa 59‑132, or a 67 aa substitution for aa 1‑82. Over aa 434‑531, human PKM2 shares 95% aa sequence identity with mouse PKM2.
