Anti-Integrin, beta 4 antibodies are protein reagents that detect specific antigens. The Integrin, beta 4 antigen is another term for the human protein integrin subunit beta 4, encoded by the ITGB4 gene. The protein is known to function in autophagy pathways and cell adhesion, among other biological roles. Canonically, it has an amino acid length of 1822 residues and a mass of 202.2 kilodaltons. Its subcellular localization is in the cell membrane and it is expressed in many tissues, such as the cervix, urinary bladder, and cerebral cortex. The Integrin, beta 4 protein is a member of the Integrin beta chain protein family. Other alias names for Integrin, beta 4 include CD104, GP150, and JEB5A.
