Protein Structure

UniProt Annotation

Function

May contribute to the transparency and refractive index of the lens. Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions.

Subcellular Localization

Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. Note=Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles. {ECO:0000250}.

Disease Associations

Tissue Specificity

Lens as well as other tissues.
