  • Application notesIs unsuitable for Flow Cyt.
  • Target

    • FunctionMay contribute to the transparency and refractive index of the lens.
    • Tissue specificityLens as well as other tissues.
    • Involvement in diseaseDefects in CRYAB are the cause of myofibrillar alpha-B crystallin-related (MFM-CRYAB) [MIM:608810]. A neuromuscular disorder that results in weakness of the proximal and distal limb muscles, weakness of the neck, velopharynx and trunk muscles, hypetrophic cardiomyopathy, and cataract in a subset of patients.
    • Sequence similaritiesBelongs to the small heat shock protein (HSP20) family.
    • Cellular localizationCytoplasm. Nucleus. Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles.
