Cloning of a T-type Ca2+ channel isoform in insulin-secreting cells.
1 Jan 2000
Abstract excerpt
The T-type Ca2+ channel is an important determinant of electrical activity and of Ca2+ influx in rat and human pancreatic beta-cells. We have identified and sequenced a cDNA encoding a T-type Ca2+ channel alpha1-subunit derived from INS-1, the rat insulin-secreting cell line. The sequence of the cDNA indicates a protein composed of 2,288 amino acids that shares 96.3% identity to alpha1G, the neuronal T-type Ca2+...
