Biological Activity

Description

PKM2 Protein, Human (530a.a, His) is a recombinant PKM2 protein with a His-Flag. PKM2 Protein is one of the rate-limiting enzymes in glycolysis[3].

Background

PKM2 is specifically expressed in proliferating cells, such as embryonic stem cells, embryonic carcinoma cells, and various cancer cells.
PKM2 functions as a glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP. PKM2 is one of the rate-limiting enzymes in glycolysis, interacts with mitofusin 2 (MFN2), a key regulator of mitochondrial fusion, to promote mitochondrial fusion and OXPHOS, and attenuate glycolysis[1][2][3].

Verified Bioactivity

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
