Anti-BICD cargo adaptor 1 antibodies are used in the immunodetection of the protein encoded by the BICD1 gene. In humans, the canonical protein has a reported length of 975 amino acid residues and a mass of 110.8 kDa. Its subcellular localization is in the golgi. Alternative splicing is reported to yield 4 different isoforms for this protein. It is reported to be expressed in the brain, heart and skeletal muscle. A member of the BicD protein family, it is reported to regulate coat complex coatomer protein I (COPI)-independent Golgi-endoplasmic reticulum transport by recruiting the dynein-dynactin motor complex. Other names for this target antigen include protein bicaudal D homolog 1, bicaudal D homolog 1, cytoskeleton-like bicaudal D protein homolog 1, and BICD.
