Α2Δ 1 Calcium Channel Subunit is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
α2δ-1 (CACNA2D1) is an auxiliary subunit of voltage-gated calcium channels that plays crucial roles in channel trafficking, localization, and modulation. It is the primary target of gabapentinoid analgesics. [1]
