Entrez gene summary

This gene encodes an alpha-1 subunit of a voltage-dependent calcium channel. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization. The alpha-1 subunit consists of 24 transmembrane segments and forms the pore through which ions pass into the cell. The calcium channel consists of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. There are multiple isoforms of each of these proteins, either encoded by different genes or the result of alternative splicing of transcripts. The protein encoded by this gene binds to and is inhibited by dihydropyridine. Alternative splicing results in many transcript variants encoding different proteins. Some of the predicted proteins may not produce functional ion channel subunits. [provided by RefSeq, Oct 2012]

Staining summary

Endothelial cells, Leydig cells, peripheral nerves, myoepithelial cells and megakaryocytes showed strong cytoplasmic positivity. Strong cytoplasmic and membranous staining was observed in thyroid and alveolar cells. Respiratory, transitional and squamous epithelia, renal tubules, glandular cells in male genital tract, smooth and heart muscle displayed moderate staining. Endothelial cells were distinctly stained. Other normal tissues were weakly stained or negative.
