Anti-DC44 antibodies enable researchers to detect and measure the DC44 antigen in biological samples. This target is a reported synonym of the FUNDC2 gene, which encodes FUN14 domain containing 2. This protein is known to function in autophagy pathways, among other biological roles. The human version of DC44 has a canonical amino acid length of 189 residues and a protein mass of 20.7 kilodaltons. It is reported to be localized in the nucleus and mitochondria of cells and notably expressed in many tissues, such as the adrenal gland and cerebral cortex. DC44 is a member of the FUN14 protein family.
