Ca2+ Dependence of Volume-Regulated VRAC/LRRC8 and TMEM16A Cl– Channels

Frontiers in Cell and Developmental Biology, 2020
All vertebrate cells activate Cl– currents (ICl,swell) when swollen by hypotonic bath solution. The volume-regulated anion channel VRAC has now been identified as LRRC8/SWELL1.

TMEM16A Ca2+‐activated Cl− channel: Functional interactions with cytoskeletal and membrane‐associated proteins

The Journal of Physiology, EarlyView.
Abstract figure legend The calcium‐activated chloride (ClCa) channel TMEM16A (also known as ANO1) plays critical roles in ion transport, neurotransmission and smooth muscle contraction. Dysregulation of TMEM16A channel activity contributes to the development and progression of various diseases.

Extracellular Chloride Regulates TMEM16A Gating [PDF]

Biophysical Journal, 2015
The gating mechanism of TMEM16A, an essential subunit of the Ca2+-activated Cl- channel, remains incompletely understood. Gating of TMEM16A channels is complex because elevation of intracellular calcium concentration ([Ca2+]i), strong depolarizations (Vm), and high extracellular Cl or highly permeant anions seem to contribute.

Update on cellular expression and function of ANO1 channels in urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.

Secreted CLCA1 modulates TMEM16A to activate Ca2+-dependent chloride currents in human cells

eLife, 2015
Calcium-activated chloride channel regulator 1 (CLCA1) activates calcium-dependent chloride currents; neither the target, nor mechanism, is known. We demonstrate that secreted CLCA1 activates calcium-dependent chloride currents in HEK293T cells in a ...

Molecular Mechanisms of Electric Signals Generated at Corneal Wounds

The FASEB Journal, Volume 40, Issue 16, 31 August 2026.
Corneal injury triggers cell signaling (including calcium waves) leading to ion channel up‐regulation, increased ion pumping, and enhanced wound electric signals which stimulate wound healing. ABSTRACT Over 150 years ago, it was demonstrated that wounds produce electric fields and currents.

Structural and Biophysical Analysis of the CLCA1 VWA Domain Suggests Mode of TMEM16A Engagement

Cell Reports, 2020
Summary: The secreted protein calcium-activated chloride channel regulator 1 (CLCA1) utilizes a von Willebrand factor type A (VWA) domain to bind to and potentiate the calcium-activated chloride channel TMEM16A.

Smooth muscle cell polycystin 1 (PKD1) is dispensable for physiological regulation of arterial contractility

The Journal of Physiology, Volume 604, Issue 15, Page 6348-6368, 1 August 2026.
Abstract figure legend Physiological functions of PKD1, a large transmembrane polycystin protein, are unclear. Previous results obtained using germline non‐specific knockout mice suggested that PKD1 regulates arterial smooth muscle cell contractility.
