Rabbit anti Human Calcium Channel

Rabbit anti Human Calcium Channel, Polyclonal, IgG

Background: Voltage-dependent calcium channels (VDCCs) are large (>400 kDa) heteromers which contain, minimally, three core subunits 1, 2/ , in a 1:1:1 stoichiometry1. Expression of VDCC gene products in Xenopus oocytes, or transfected cells shows that the 1 subunits contain the ion channel pore while the auxiliary 2/ and subunits confer optimal cell surface expression and channel kinetics1. Until recently, the only exception to the above paradigm was the skeletal muscle VDCC, which, in addition to the 1, 2/ , core motif, also has an additional tightly associated integral membrane glycoprotein subunit termed 1. Upon co-expression with the 1.1, 2/ 1, 1a subunits of the skeletal muscle VDCC, subunits alter the peak currents, and the kinetics of channel activation and inactivation with the overall effect being a normalisation of currents to those resembling the endogenous channel2. Together, these results suggest that subunits modulate skeletal muscle VDCCs by stabilising their conformation.
The 2 subunits, or stargazin, the product of a gene mutated in the stargazer mouse, is a homolog of the 1 channel and is selectively expressed in the brain. It is considered to be a putative neuronal Ca2+ channel subtype mainly based on its homology to the 1.
