About CACNA1I

Cytogenetic location: 22q13.1 Genomic coordinates (GRCh38): 22:39,570,753-39,689,735 (from NCBI)

This gene has 5 transcripts (splice variants), 265 orthologues, 26 paralogues and is associated with 1 phenotype. Biased expression in brain (RPKM 1.3), adrenal (RPKM 0.7) and 10 other tissues.

Summary

This gene encodes the pore-forming alpha subunit of a voltage gated Calcium Channel. The encoded protein is a member of a subfamily of calcium channels referred to as is a low voltage-activated, T-type, Calcium Channel. The channel encoded by this protein is characterized by a slower activation and inactivation compared to Other T-type calcium channels. This protein may be involved in calcium signaling in neurons. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2011]
