Opis

Opis ogólny

Research area: Cell Signaling
The gene LDHA (L-lactate dehydrogenase A chain) is mapped to human chromosome 11p15.[1] It is a subunit of lactate dehydrogenase.[2]In particular, lactic dehydrogenase A (LDHA) is mainly found in skeletal muscle, and for that reason is known as the M subunit. This recombinant form of LDHA has a C-terminal histidine-tag.

Zastosowanie

L-Lactate Dehydrogenase (LDHA) has been used in in vitro phosphoglycerate mutase 1 (PGAM1) inhibitors screening assay.[3] It has also been used in a colorimetric assay for determining lactate concentration in conditioned media.[4]

Działania biochem./fizjol.

L-lactic dehydrogenase catalyzes the conversion of L-lactate into L-pyruvate while reducing NAD⁺ to NADH and H⁺.[5]  L-lactate dehydrogenase A chain (LDHA), an enzyme involved in pyruvate metabolism,[6] LDH is responsible for the conversion of pyruvate to lactate, the final step of glycolysis. It is overexpressed in various cancers.[6][7] LDHA regulates the microenvironment of developing tumors by the hypoxia-inducible factor (HIF)-signaling pathway.[7] LDHA aids in the NAD⁺ regeneration during the β-oxidation of fatty acid.[8] LDHA (L-lactate dehydrogenase A chain) is responsible for the conversion of pyruvate to lactate, the final step of glycolysis. It is overexpressed in various cancers. In cancer cells, HIF-1a (hypoxia-inducible factor) induces the expression of LDHA, which helps in maintaining glycolysis in cells.[2]

L-lactic dehydrogenase catalyzes the conversion of L-lactate into L-pyruvate while reducing NAD⁺ to NADH and H⁺.
