Anti-MLDP antibodies enable researchers to detect and measure the MLDP antigen in biological samples. This target is a reported synonym of the PLIN5 gene, which encodes perilipin 5. This protein is known to function in the metabolism of lipids, among other biological roles. The human version of MLDP has a canonical amino acid length of 463 residues and a protein mass of 50.8 kilodaltons. It is reported to be localized in the mitochondria and cytoplasm of cells. MLDP is a member of the Perilipin protein family.
