Monoclonal Anti-Dihydropyridine Receptor (α₂ Subunit) antibody produced in mouse，100UL，D219-100UL，Sigma

General description

Dihydropyridine Receptor (DHPR) is a heteropentamer calcium ion channel and comprises of α1,α2/δ,β and γ subunits. It is localized in the skeletal muscle in the t-tubule membrane. The α2subunit of DHPR is a glycosylated subunit and is anchored on the membrane.

Immunogen

Biochem/physiol Actions

Dihydropyridine Receptor (DHFR) α1 subunit is the voltage-sensor. DHPR interacts with ryanodine receptor (RyR) and also mediates excitation-contraction (EC) coupling in cardiac and skeletal muscles. Mutation in the DHPR (E1014K) affects its affinity and selectivity towards calcium permeation. Additionally, it also plays a key role in the synaptic transmission.
Reacts specifically with the α₂ subunit of the DHP receptor. Strong reactivity is observed with the α₂ subunit in rat, mouse, guinea pig, rabbit skeletal and cardiac muscle, and rat brain and lung tissue. Weaker reactivity is observed with rat kidney, liver and spleen tissues. By immunohistochemistry, double rows of discrete punctate staining represent pairs of triads on the opposing sides of the Z-lines.

Physical form
