Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Calcium-binding protein critical for proper photoreceptor cell maintenance and function. Plays a role in intracellular calcium homeostasis by decreasing ATP-induced calcium release (PubMed:23023331, PubMed:26173970, PubMed:26426422). May be involved in the mechanotransduction process (By similarity).By similarity3 Publications

Miscellaneous

The binding of either calcium or magnesium significantly increases the structural stability of the protein in comparison to apo-CIB (calcium- and magnesium-free form) (PubMed:22779914).1 Publication

Deafness, autosomal recessive, 48 (DFNB48)3 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. DFNB48 patients have prelingual onset of severe to profound sensorineural hearing loss affecting all frequencies.

The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionUSH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH1 is characterized by profound congenital sensorineural deafness, absent vestibular function and prepubertal onset of progressive retinitis pigmentosa leading to blindness.
