WebFeb 8, 2024 · Abstract. HSPB5 or alpha B-crystallin (CRYAB), originally identified as lens protein, is one of the most widespread and represented of the human small heat shock proteins (sHSPs). It is greatly expressed in tissue with high rates of oxidative metabolism, such as skeletal and cardiac muscles, where HSPB5 dysfunction is associated with a … WebCrystallins are present in high concentrations in the lens fiber cells [8] and are divided into two major families, α and βγ crystallins [9]. α-Crystallin forms supramolecular complexes and acts as a molecular chaperone for partially unfolded proteins [[10], [11], [12]].The β- and γ-crystallins are structurally similar they have two domains (bilobed conformation) …
