The antibody was affinity-purified from rabbit serum by affinity-chromatography using specific immunogen.
Background
Voltage-gated Ca(2+) and Na+ channels have 4 homologous domains, each containing 6 transmembrane segments, S1 to S6. TPCN1 is similar to these channels, but it has only 2 domains containing S1 to S6 (Ishibashi et al., 2000 [PubMed 10753632]).[supplied by OMIM, Mar 2008],
Function
domain:Each of the two internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.,function:May function as one of the major voltage-gated Ca(2+) channel (VDCC) across the plasma membrane.,similarity:Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family.,subunit:Dimer .,tissue specificity:Highest expression found in the heart and kidney, and lowest expression found in the spleen.,
