LDHA
GeneName
LDHA
Summary
LDHA, also known as D lactate dehydrogenase or LDH A, is a 37 kDa enzyme that catalyses the conversion of pyruvate to lactate in the glycolytic pathway, facilitating anaerobic metabolism. It is primarily expressed in tissues with high glycolytic activity, such as muscle and brain, and is localised in the cytosol and mitochondria, among other cellular compartments. LDHA plays a crucial role in the lactate metabolic process and is involved in various biological processes including glucose catabolism and the development of the substantia nigra. Its activity is essential for maintaining energy production under hypoxic conditions and is linked to the regulation of cellular metabolism.
Importance
LDHA is relevant to: - Cancer metabolism, as it supports the Warburg effect where cancer cells preferentially convert glucose to lactate even in the presence of oxygen - Metabolic disorders, including lactic acidosis, due to its role in lactate production and clearance - Neurodegenerative diseases, particularly in the context of neuronal energy metabolism and the development of the substantia nigra - Exercise physiology, since it is involved in muscle fatigue and recovery processes during intense physical activity
Top Products
For researchers investigating LDHA, we highly recommend the top-selling recombinant antibody, Anti-Lactate Dehydrogenase antibody [EPR1564] (ab101562). This well-cited antibody has garnered 86 citations, reflecting its reliability and trust within the scientific community. It has been validated for use in Western blotting (WB) and immunohistochemistry (IHC), making it a versatile choice for various experimental needs. The recombinant nature of this antibody ensures batch-to-batch consistency, providing researchers with confidence in their results. The Anti-Lactate Dehydrogenase antibody [98A-1F9BB1] ELISA Kit (ab135396), supported by 5 citations, is an excellent option for researchers looking to accurately measure LDHA levels in their samples.
