Background

AlphaB Crystallin (CRYAB, also known as Crystallin alpha -B chain and HspB5) is a 22‑23 kDa member of the HSP20 family of proteins. It has widespread expression in many tissues in addition to lens epithelium, where it noncovalently oligomerizes with CRY-alpha A to generate a transparent 350‑1000 kDa alpha -Crystallin protein complex. Human CRYAB is 175 amino acids (aa) in length. There is a alpha -Crystallin Hsp domain over aa 66‑149. Multiple posttranslational modifications may exist. The
N‑terminal Met and MetAspIleAlaIleHis sequence is occasionally cleaved. There is also phosphorylation at Ser45 and 59, potential O-GlcNAc modification at Thr158, 162 or 170, and acetylation at Lys92. There is an alternate start site at Met68 that may be accompanied by a 47 aa substitution for aa 109‑175. Full-length human CRYAB is 54% aa identical to CRY-AlphaA, and 98% aa identical to mouse CRYAB.
