Protein attributes

Sequence length	314 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Plays an essential role in the mitochondrial beta-oxidation of short chain fatty acids. Exerts it highest activity toward 3-hydroxybutyryl-CoA.
Catalytic activity	(S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH.
Pathway	Lipid metabolism; fatty acid beta-oxidation.
Subunit structure	Homodimer.
Subcellular location	Mitochondrion matrix.
Tissue specificity	Expressed in liver, kidney, pancreas, heart and skeletal muscle.
Involvement in disease	3-alpha-hydroxyacyl-CoA dehydrogenase deficiency (HADH deficiency) [MIM:231530]: A metabolic disorder with various clinical presentations including hypoglycemia, hepatoencephalopathy, myopathy or cardiomyopathy, and in some cases sudden death. Note: The disease is caused by mutations affecting the gene represented in this entry. Familial hyperinsulinemic hypoglycemia 4 (HHF4) [MIM:609975]: Most common cause of persistent hypoglycemia in infancy. Unless early and aggressive intervention is undertaken, brain damage from recurrent episodes of hypoglycemia may occur. HHF4 should be easily recognizable by analysis of acylcarnitine species and that this disorder responds well to treatment with diazoxide. It provides the first 'experiment of nature' that links impaired fatty acid oxidation to hyperinsulinism and that provides support for the concept that a lipid signaling pathway is implicated in the control of insulin secretion. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.12
Sequence similarities	Belongs to the 3-hydroxyacyl-CoA dehydrogenase family.
