Anti-Protein tyrosine Phosphatase-Like A Domain Containing 2 antibodies enable researchers to detect and measure the Protein tyrosine Phosphatase-Like A Domain Containing 2 antigen in biological samples. This target is a reported synonym of the HACD4 gene, which encodes 3-hydroxyacyl-CoA dehydratase 4. This protein is known to function in the metabolism of lipids, among other biological roles. The human version of Protein tyrosine Phosphatase-Like A Domain Containing 2 has a canonical amino acid length of 232 residues and a protein mass of 27.5 kilodaltons. It is reported to be localized in the ER of cells. Other names for this target antigen include very-long-chain (3R)-3-hydroxyacyl-CoA dehydratase 4 and protein tyrosine phosphatase-like A domain containing 2.
