products description :
Defects in HADHB are a cause of trifunctional protein deficiency (TFP deficiency) [MIM:609015]. The clinical manifestations are very variable and include hypoglycemia, cardiomyopathy and sudden death. Phenotypes with mainly hepatic and neuromyopathic involvement can also be distinguished. Biochemically, TFP deficiency is defined by the loss of all three enzyme activities of the TFP complex.

ncbi summary :
This gene encodes the beta subunit of the mitochondrial trifunctional protein, which catalyzes the last three steps of mitochondrial beta-oxidation of long chain fatty acids. The mitochondrial membrane-bound heterocomplex is composed of four alpha and four beta subunits, with the beta subunit catalyzing the 3-ketoacyl-CoA thiolase activity. Mutations in this gene result in trifunctional protein deficiency. The encoded protein can also bind RNA and decreases the stability of some mRNAs. The genes of the alpha and beta subunits of the mitochondrial trifunctional protein are located adjacent to each other in the human genome in a head-to-head orientation. Alternatively spliced transcript variants have been found; however, their full-length nature is not known. [provided by RefSeq, Jul 2008]
uniprot summary :
Catalytic activity: Acyl-CoA + acetyl-CoA = CoA + 3-oxoacyl-CoA. Ref.8. Pathway: Lipid metabolism; fatty acid beta-oxidation. Subunit structure: Octamer of 4 alpha (HADHA) and 4 beta (HADHB) subunits. Ref.10. Subcellular location: Mitochondrion. Involvement in disease: Defects in HADHB are a cause of trifunctional protein deficiency (TFP deficiency) [. MIM:609015]. The clinical manifestations are very variable and include hypoglycemia, cardiomyopathy and sudden death. Phenotypes with mainly hepatic and neuromyopathic involvement can also be distinguished. Biochemically, TFP deficiency is defined by the loss of all three enzyme activities of the TFP complex. Sequence similarities: Belongs to the thiolase family. Sequence caution: The sequence BAA22061.1 differs from that shown. Reason: Erroneous gene model prediction.
