ANO1 Antibodies

Target Information

Calcium-activated chloride channel (CaCC). Plays a role in transepithelial anion transport and smooth muscle contraction. Required for the normal functioning of the interstitial cells of Cajal (ICCs) which generate electrical pacemaker activity in gastrointestinal smooth muscles. Acts as a major contributor to basal and stimulated chloride conductance in airway epithelial cells and plays an important role in tracheal cartilage development. Required for CFTR activation by enhancing endoplasmic reticulum Ca2+ store release and is also required for CFTR membrane expression. Required for basal and ATP-dependent mucus secretion in airways and intestine, probably by controlling exocytosis of mucus-filled granules by providing Ca2+ to an apical signaling compartment. Contributes to airway mucus expression induced by interleukins IL3 and IL8 and by the asthma-associated protein CLCA1 and is required for expression of mucin MUC5AC. However, was shown in another study not to be required for MUC5AC expression. Plays a role in the propagation of Ca2+ waves in Kolliker's organ in the cochlea and contributes to the refinement of auditory brainstem circuitries prior to hearing onset. In vomeronasal sensory neurons, modulates spontaneous firing patterns in the absence of stimuli as well as the firing pattern of pheromone-evoked activity. Responsible for calcium-activated chloride channel activity in type I taste cells of the vallate papillae. Acts as a heat sensor in nociceptive neurons. In dorsal root ganglion neurons, plays a role in mediating non-histaminergic Mas-related G-protein coupled receptor (MRGPR)-dependent itching, acting as a downstream effector of MRGPRs. In the developing brain, required for the Ca2+-dependent process extension of radial glial cells. Isoform 4: Calcium-activated chloride channel (CaCC). Contributes to calcium-activated chloride secretion in human sweat gland epithelial cells. Shows increased basal chloride permeability and decreased Ca2+-induced chloride permeability. Isoform 5: Calcium-activated chloride channel (CaCC). Shows increased sensitivity to intracellular Ca2+. Homodimer. Interacts with CFTR. Interacts with TRPV4. Belongs to the anoctamin family. Broadly expressed with higher levels in liver, skeletal muscle and gastrointestinal muscles. 5 alternatively spliced human isoforms have been reported.
