Western blot analysis of HADHA using anti-HADHA antibody. Lane 1: human Jurkat whole cell lysates, Lane 2: human 293T whole cell lysates, Lane 3: human Hela whole cell lysates, Lane 4: rat liver tissue lysates, Lane 5: rat kidney tissue lysates, Lane 6: mouse liver tissue lysates, Lane 7: mouse kidney tissue lysates, Lane 8: mouse NIH/3T3 whole cell lysates. After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-HADHA antibody at 0.5 ug/ml overnight at 4oC, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal was developed using enhanced chemiluminescent. A predominant band is detected at ~79 kDa, consistent with the reported migration of the full-length alpha subunit. An additional ~26 kDa band is present, consistent with a stable proteolytic fragment of HADHA commonly observed in mitochondrial or tissue lysates.

Description

HADHA antibody detects Hydroxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit alpha, a mitochondrial enzyme essential for fatty acid beta-oxidation. The UniProt recommended name is Trifunctional enzyme subunit alpha, mitochondrial (HADHA), which functions as part of the mitochondrial trifunctional protein (MTP) complex. This alpha subunit possesses both long-chain enoyl-CoA hydratase and long-chain 3-hydroxyacyl-CoA dehydrogenase activities, while its partner, HADHB, provides 3-ketoacyl-CoA thiolase activity.

Functionally, HADHA antibody recognizes a 79 kDa protein localized to the inner mitochondrial membrane, where it catalyzes key reactions in the beta-oxidation pathway of long-chain fatty acids. HADHA converts long-chain enoyl-CoA substrates to hydroxyacyl-CoA and subsequently to 3-ketoacyl-CoA intermediates, producing NADH and acetyl-CoA for energy generation. This process is vital for sustaining ATP production in tissues with high oxidative energy requirements, including heart, skeletal muscle, and liver. Disruption of HADHA function impairs mitochondrial fatty acid oxidation, leading to metabolic imbalance and accumulation of toxic lipid intermediates.

The HADHA gene is located on chromosome 2p23.3 and encodes one of the two subunits forming the hetero-octameric mitochondrial trifunctional protein complex. HADHA and HADHB assemble into four alpha-beta dimers that operate cooperatively in fatty acid oxidation. The enzyme's activity is critical during fasting and prolonged exercise when fatty acids serve as the major energy source. Mutations in HADHA result in long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency (LCHAD deficiency), a metabolic disorder characterized by hypoglycemia, hepatic dysfunction, and cardiomyopathy.

HADHA antibody is used to investigate mitochondrial metabolism, lipid oxidation, and energy regulation. It is particularly valuable in studies of metabolic disorders, mitochondrial dysfunction, and lipid-associated diseases. In cellular research, HADHA serves as a mitochondrial marker and is often co-stained with oxidative phosphorylation proteins to assess organelle function. Reduced HADHA expression is associated with defective energy metabolism in diabetes, fatty liver disease, and heart failure. Conversely, upregulation may indicate compensatory enhancement of fatty acid catabolism under stress.

Structurally, HADHA contains an N-terminal enoyl-CoA hydratase domain and a C-terminal 3-hydroxyacyl-CoA dehydrogenase domain, both dependent on NAD+ for catalytic turnover. Post-translational regulation of HADHA involves acetylation, phosphorylation, and interactions with acyl-CoA binding proteins that modulate substrate specificity. Its proper function is essential for maintaining mitochondrial redox balance and preventing lipid-induced oxidative stress.

NSJ Bioreagents provides HADHA antibody reagents validated for research use in mitochondrial biology, energy metabolism, and metabolic disease models. These antibodies enable high-specificity detection in western blotting, immunohistochemistry, and confocal imaging applications.
