Anti-crystallin beta A1 antibodies are used in the immunodetection of the protein encoded by the CRYBA1 gene. In humans, the canonical protein has a reported length of 215 amino acid residues and a mass of 25.2 kDa. A member of the Beta/gamma-crystallin protein family, it is known to be involved with eye development and cytokine-mediated signaling pathways. Post-translational modifications have been described, including protein cleavage. Other names for this target antigen include CTRCT10, beta-crystallin A3, beta crystallin A3 chain transcript CN, beta crystallin A3 chain transcript LAM, and CRYB1.
