Specifications

Clone Host Grade Applications
Polyclonal Goat Affinity Purified B
AlphaB Crystallin (CRYAB, also known as Crystallin alpha-B chain and HspB5) is a 22-23kD 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-alphaA to generate a transparent 350-1000kD alpha-Crystallin protein complex. Human CRYAB is 175aa in length. There is a alpha-Crystallin Hsp domain over aa66-149. 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 47aa substitution for aa109-175. Full-length human CRYAB is 54% aa identical to CRY-AlphaA, and 98% aa identical to mouse CRYAB.
