Protein attributes

Sequence length	175 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

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.
Subunit structure	Heteropolymer composed of three CRYAA and one CRYAB subunits. Aggregates with homologous proteins, including the small heat shock protein HSPB1, to form large heteromeric complexes. Inter-subunit bridging via zinc ions enhances stability, which is crucial as there is no protein turn over in the lens. Interacts with HSPBAP1 and TTN/titin. Ref.14 Ref.18 Ref.23 Ref.25 Ref.28 Ref.31
Subcellular location	Cytoplasm. Nucleus. Note: Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles. Ref.24
Tissue specificity	Lens as well as other tissues.
Involvement in disease	Myopathy, myofibrillar, 2 (MFM2) [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. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.22 Ref.29 Ref.30 Cataract, posterior polar, 2 (CTPP2) [MIM:613763]: A subcapsular opacity, usually disk-shaped, located at the back of the lens. It can have a marked effect on visual acuity. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.19 Myopathy, myofibrillar, fatal infantile hypertonic, alpha-B crystallin-related (MFMFIH-CRYAB) [MIM:613869]: A muscular dystrophy with onset in the first weeks of life after a normal neonatal period. Affected infants show rapidly progressive muscular rigidity of the trunk and limbs associated with increasing respiratory difficulty resulting in death before age 3 years. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.26
Sequence similarities	Belongs to the small heat shock protein (HSP20) family.
Mass spectrometry	Molecular mass is 20201 Da from positions 1 - 175. Determined by ESI. Ref.15 Molecular mass is 20281 Da from positions 1 - 175. Determined by ESI. With 1 phosphate group. Ref.15 Molecular mass is 20360 Da from positions 1 - 175. Determined by ESI. With 2 phosphate groups. Ref.15 Molecular mass is 20199 Da from positions 1 - 175. Determined by ESI. Ref.17 Molecular mass is 20278 Da from positions 1 - 175. Determined by ESI. With 1 phosphate group. Ref.17
