May contribute to the transparency and refractive index of the lens.
Specificity
Natural and recombinant Pig Alpha-crystallin B chain
Subcellular Location
Cytoplasm Nucleus Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles.
Homodimer. Aggregates with homologous proteins, including alpha-A-crystallin and the small heat shock protein HSPB1, to form large heteromeric complexes. Interacts with HSPBAP1 and TTN/titin.
