Involvement in diseasei

Myopathy, myofibrillar, 2 (MFM2)3 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disc 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.

Cataract 16, multiple types (CTRCT16)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn 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.

Myopathy, myofibrillar, fatal infantile hypertonic, alpha-B crystallin-related (MFMFIH-CRYAB)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disc 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.

Cardiomyopathy, dilated 1II (CMD1II)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.

Interactioni

Subunit structurei

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).5 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
