About IQCB1

Cytogenetic location: 3q13.33 Genomic coordinates (GRCh38): 3:121,769,761-121,835,060 (from NCBI)

This gene has 7 transcripts (splice variants), 200 orthologues and is associated with 4 phenotypes. Ubiquitous expression in testis (RPKM 16.8), lymph node (RPKM 10.7) and 25 other tissues.

Summary

This gene encodes a nephrocystin protein that interacts with Calmodulin and the retinitis pigmentosa GTPase regulator protein. The encoded protein has a central coiled-coil region and two calmodulin-binding IQ domains. It is localized to the primary cilia of renal epithelial cells and connecting cilia of photoreceptor cells. The protein is thought to play a role in ciliary function. Defects in this gene result in Senior-Loken syndrome type 5. Alternative splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Jan 2016]
