Background: AlphaB Crystallin/CRYAB

CRY-alpha B (crystalline alpha -B chain/CRYAB; also HspB5) is a 22-23 kDa member of the HSP20 family of proteins.  It has widespread expression, and is found in lens epithelium where it noncovalently oligomerizes with CRYAA to generate a transparent 350-1000 kDa alpha -crystalline protein complex.  Human CRYAB is 175 amino acids (aa) in length. It contains an alpha -crystalline Hsp domain over aa 66-149.  Multiple post-translational modifications may exist. The N-terminal Met and MetAspIleAlaIleHis sequence is occasionally cleaved.  It may also be phosphorylated at Ser45 and 59, be potentially O-GlcNAc modified at Thr158, 162 or 170, and acetylated at Lys92.  An alternate start site at Met68 may be accompanied by a 47 aa substitution for aa 109-175.  Full-length human CRYAB shares 54% aa sequence identity with CRYAA, and 98% aa identity with mouse CRYAB.
