    CIB2 Summary & Protein Information

    CIB2 Background

    Gene Summary: The amino acid sequence the protein encoded by this gene is similar to that of KIP/CIB, calcineurin B, and calmodulin. This suggests that the encoded protein may be a Ca2+-binding regulatory protein that interacts with DNA-dependent protein kinase catalytic subunit (DNA-PKcs).
    General information above from NCBI
    Subcellular location: Photoreceptor inner segment (By similarity). Note=Expressed in inner and outer segments of photoreceptor cells, as well as in the pigmented epithelium. Also observed in the inner and outer plexiform layers and in the ganglion cell layer (By similarity).
    Tissue specificity: Ubiquitous.
    Involvement in disease: Deafness, autosomal recessive, 48 (DFNB48) [MIM:609439]: A 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. Note=The disease is caused by mutations affecting the gene represented in this entry.
    Usher syndrome 1J (USH1J) [MIM:614869]: USH 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. Note=The disease is caused by mutations affecting the gene represented in this entry.
    Sequence similarity: Contains 3 EF-hand domains.C
