Anti-dnd antibodies are protein reagents that detect specific antigens. The dnd antigen is another term for the human protein lysosomal associated membrane protein 2, encoded by the LAMP2 gene. The protein is known to play an important role in chaperone-mediated autophagy, a process that mediates lysosomal degradation of proteins in response to various stresses and as part of the normal turnover of proteins with a long biological half-live. Canonically, it has an amino acid length of 410 residues and a mass of 45 kilodaltons. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and cell membrane and it is widely expressed in many tissue types. The dnd protein is a member of the LAMP protein family. Other alias names for dnd include CD107b and LAMPB.
