Mammalian lens crystallins are divided into alpha, beta, and gamma families. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (HSP20) family. They act as molecular chaperones although they do not renature proteins and releas...

Entrez Gene Summary for CRYAB Gene

  • Mammalian lens crystallins are divided into alpha, beta, and gamma families. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (HSP20) family. They act as molecular chaperones although they do not renature proteins and release them in the fashion of a true chaperone; instead they hold them in large soluble aggregates. These heterogeneous aggregates consist of 30-40 subunits; the alpha-A and alpha-B subunits have a 3:1 ratio, respectively. Two additional functions of alpha crystallins are an autokinase activity and participation in the intracellular architecture. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. Alpha-A and alpha-B gene products are differentially expressed; alpha-A is preferentially restricted to the lens and alpha-B is expressed widely in many tissues and organs. Elevated expression of alpha-B crystallin occurs in many neurological diseases; a missense mutation cosegregated in a family with a desmin-related myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2019]

    Molecular mass:
    20159 Da
    Quaternary structure:
    • Heteropolymer composed of three CRYAA and one CRYAB subunits (PubMed:20836128). Aggregates with homologous proteins, including the small heat shock protein HSPB1, to form large heteromeric complexes (PubMed:10751411). Inter-subunit bridging via zinc ions enhances stability, which is crucial as there is no protein turn over in the lens (PubMed:22890888). Interacts with HSPBAP1 and TTN/titin (PubMed:14676215). Interacts with TMEM109 (PubMed:23542032). Interacts with DES; binds rapidly during early stages of DES filament assembly and a reduced binding seen in the later stages (PubMed:28470624). Interacts with TMED10; the interaction mediates the translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and thereby secretion (PubMed:32272059).

Localization for CRYAB Gene

Subcellular locations from UniProtKB/Swiss-Prot for CRYAB Gene

Cytoplasm. Nucleus. Secreted. Note=Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles (PubMed:19464326). Localizes at the Z-bands and the intercalated disk in cardiomyocytes (PubMed:28493373). Can be secreted; the secretion is dependent on protein unfolding and facilitated by the cargo receptor TMED10; it results in protein translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) followed by vesicle entry and secretion (PubMed:32272059). {ECO:0000269 PubMed:19464326, ECO:0000269 PubMed:28493373, ECO:0000269 PubMed:32272059}.

CRYAB_HUMAN
  • Myopathy, myofibrillar, 2 (MFM2) [MIM:608810]: A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM2 is characterized by weakness of the proximal and distal limb muscles, weakness of the neck, velopharynx and trunk muscles, hypertrophic cardiomyopathy, and cataract in a subset of patients. {ECO:0000269 PubMed:12601044, ECO:0000269 PubMed:14681890, ECO:0000269 PubMed:21920752, ECO:0000269 PubMed:9731540}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Cataract 16, multiple types (CTRCT16) [MIM:613763]: An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. CTRCT16 includes posterior polar cataract, among others. Posterior polar cataract is a subcapsular opacity, usually disk-shaped, located at the back of the lens. {ECO:0000269 PubMed:11577372}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Note=CRYAB mutations may be involved in restrictive cardiomyopathy (RCM), a rare non-ischemic myocardial disease. RCM is characterized by restrictive ventricular-filling physiology in the presence of normal or reduced diastolic and/or systolic volumes (of 1 or both ventricles), biatrial enlargement, and normal ventricular wall thickness. {ECO:0000269 PubMed:28493373}.
  • Myopathy, myofibrillar, fatal infantile hypertonic, alpha-B crystallin-related (MFMFIH-CRYAB) [MIM:613869]: A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFMFIH-CRYAB has 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. {ECO:0000269 PubMed:21337604}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Cardiomyopathy, dilated 1II (CMD1II) [MIM:615184]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269 PubMed:16483541, ECO:0000269 PubMed:16793013}. Note=The disease is caused by variants affecting the gene represented in this entry.
