Anoctamin 1 (ANO1)

Target
ANO1
Molecular classification
Ion channel, Transmembrane protein, Calcium-activated chloride channel
01

Overview

Anoctamin 1 (ANO1), also known as TMEM16A, is a voltage-gated, calcium-activated anion channel primarily conducting chloride ions. It plays critical roles in transepithelial anion transport, smooth muscle contraction, pacemaker activity, cell proliferation and migration, secretion, and neuronal excitation. Overexpression or dysregulation is linked to cancer progression and other diseases.
