MGI Phenotype

FUNCTION: This gene encodes an integral membrane protein that belongs to the calcium channel alpha-1 subunits family. Voltage-sensitive calcium channels mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes. Voltage-dependent calcium channels are multi-subunit complexes, comprised of alpha-1, alpha-2, beta and delta subunits in a 1:1:1:1 ratio. The isoform alpha-1E gives rise to R-type calcium currents and belongs to the high-voltage activated group. Calcium channels containing the alpha-1E subunit may be involved in the modulation of neuronal firing patterns, an important component of information processing. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for targeted null mutations exhibit altered R-type Ca2+ channels, increased timidity and body weight, impaired glucose tolerance, reduced locomotor activity, and lack of the cocaine stimulation of locomotor response. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a T to A transversion at position 3684 of the Cacna1e transcript in exon 25 of 47 total exons. The mutated nucleotide causes a leucine to glutamine substitution at amino acid 1228 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Cacna1e gene encodes a 2273 amino acid voltage-gated calcium (Ca²⁺) channel subunit that contains 24 transmembrane domains. The isoform alpha-1E gives rise to R-type Ca²⁺currents. R-type Ca²⁺channels belong to the 'high-voltage activated' (HVA) group and are blocked by nickel, and partially by omega-agatoxin-IIIA (omega-Aga-IIIA). They are insensitive to dihydropyridines (DHP), omega-conotoxin-GVIA (omega-CTx-GVIA), and omega-agatoxin-IVA (omega-Aga-IVA) (Uniprot Q61290). Mice homozygous for targeted null mutations exhibit altered R-type Ca²⁺ channels, increased timidity and body weight, impaired glucose tolerance, reduced locomotor activity, and lack of the cocaine stimulation of locomotor response.

The L1228Q change occurs in the fifteenth transmembrane domain, and is predicted to be possibly damaging by the PolyPhen program.
