Product DescriptionRecombinant HEK293 cell line expressing Shuman TMEM16A (transmembrane protein16A, also called as anoctamin 1, calcium-activated chloride channel (ANO1), accessionnumber NM_018043).

FormatEach vial contains 1 X 10^6 cells in 1 ml of 10% DMSO.

Mycoplasma TestingThe cell line has been screened using the PCR-based VenorGeM Mycoplasma Detectionkit (Sigma-Aldrich) to confirm the absence of Mycoplasma species.

IntroductionCalcium-activated chloride channels (CaCCs) are major regulators in numerousphysiological processes including sensory transduction, epithelial secrection, cardiac andneutonal excitation, and smooth muscle contraction.

TMEM16A (ANO1), a member of a family of putative plasma membrane proteins, isidentified as a CaCC that is activated by intracellular Ca2+ and Ca2+-mobilizing stimuli. Ithas eight putative transmembrane segments without domains evidently involved incalcium regulation. The relative permeability of TMEM16A to monovalent anions isNO₃^- > I^- > Br^- > Cl^- > F^-.
