TMEM16E/ANO5 protein is rapidly degraded via the proteasome pathway; degradation is rescued by PI3K pathway inhibition and the chemical chaperone sodium butyrate. The GDD-causing mutant TMEM16E(gdd) exhibits lower stability than wild-type. TMEM16E does not exhibit cell-surface Ca2+-activated Cl- channel (CaCC) activity due to its intracellular vesicle distribution. A putative pore-forming domain of TMEM16E disrupts CaCC activity of TMEM16A via domain swapping. |

TMEM16E carries a 35-amino-acid segment homologous to the scrambling domain in TMEM16F. When this segment replaced the corresponding region of TMEM16A, the chimeric molecule localized to the plasma membrane and supported Ca2+-dependent phospholipid scrambling, demonstrating that TMEM16E harbors a functional scrambling domain. |

TMEM16E is expressed in germ cells during spermatogenesis and localizes to the sperm tail. TMEM16E-deficient male mice show reduced sperm motility and inefficient fertilization of zona-intact eggs in vitro, while morphology, beating, mitochondrial function, capacitation, and zona pellucida binding are unaffected. |

Human TMEM16E/ANO5 displays Ca2+-dependent phospholipid scrambling (PLS) and non-selective ionic currents when overexpressed in mammalian cells, with partial plasma membrane localization. The GDD-causing T513I mutation confers gain-of-function PLS and large ion currents even at low cytosolic Ca2+, whereas the equivalent mutation in TMEM16B paralog had little effect. |

ANO5 protein is expressed as a single 107 kDa polypeptide in human skeletal muscle. Truncating mutations (c.191dupA, c.1261C>T) abolish ANO5 expression entirely; non-truncating pathogenic point mutations reduce ANO5 expression in the membrane fraction, consistent with protein destabilization and degradation. |

ANO5 overexpression confers Ca2+-dependent phospholipid scrambling and a nonselective ionic current to HEK-293 cells. Ano5-/- mouse muscle precursor cells (MPCs) exhibit defective cell fusion in culture (fewer nuclei per myotube), decreased Ca2+-dependent phosphatidylserine exposure, and reduced Ca2+-dependent outwardly rectifying ionic currents. Viral re-introduction of ANO5 rescues fusion, scrambling, and ionic currents. |

A LGMD2L patient with the c.191dupA homozygous mutation showed no ANO5 signal. A truncated ANO5 peptide (first 121 aa) resulting from a novel splice variant forms aggregates when expressed in C2C12 cells. |

ANO5-deficient patient myoblasts (carrying c.2272C>T mutation causing protein degradation) show normal myogenesis but defective plasma membrane repair (PMR). The repair deficit is linked to impaired ER-mediated cytosolic Ca2+ clearance after focal injury. Wild-type ANO5 expression or pharmacological prevention of cytosolic Ca2+ overload rescues PMR in patient cells. |

ANO5 knockdown in C2C12 myotubes causes clustered/aggregated nuclei (nuclear positioning defect) associated with reduced Kif5b protein expression. ANO5 knockdown also impairs depolarization-induced Ca2+ transients and reduces SR Ca2+ storage, associated with reduced DHPR and SERCA1 protein expression and disrupted DHPR–RyR1 co-localization. |

BVES is a novel interacting protein of ANO5 identified by proximity labeling (BioID2) and confirmed by co-immunoprecipitation. The N-terminus of ANO5 mediates interaction with the C-terminus of BVES. ANO5 and BVES co-localize at the endoplasmic reticulum membrane in muscle cells. Genome-editing disruption of either ANO5 or BVES significantly suppresses C2C12 myoblast differentiation. |

Ablation of Ano5 in mice reduces intracellular calcium transients in osteoblasts and osteoclasts, leading to defective osteoblast and osteoclast differentiation. Ano5 KO mice exhibit low bone volume, abnormal calcium deposits, and reduced WNT/β-Catenin signaling in osteoblasts and RANKL-NFATc1 signaling in osteoclasts. Parathyroid hormone treatment enhances bone strength in KO mice. |

TMEM16E (ANO5) is required for endothelial cell procoagulant activity via phosphatidylserine externalization. In an intravital laser-injury thrombosis model, PS externalization is concentrated at the vessel wall. TMEM16E-null mice show reduced vessel-wall-dependent fibrin formation. The TMEM16 inhibitor benzbromarone prevents PS externalization, EC procoagulant activity, and protects mice from thrombosis. |

Ano5 deficiency impairs osteoclastogenesis: Ano5-/- mice exhibit inhibited formation of multinucleated osteoclasts, reduced TRAP activity, decreased expression of Nfatc1, c-Fos, and osteoclast genes, disrupted actin ring formation, and less mineral resorption. RANKL-induced NF-κB signaling is suppressed in Ano5-/- osteoclasts, and this can be partially rescued by NF-κB activator. |

TMEM16E activation promotes macropinocytosis essential for plasma membrane integrity. TMEM16E externalizes phosphatidylserine associated with resting growth factor receptors, interacts with and signals through EGFR in a ligand-independent manner, stimulates PI3K, and facilitates macropinocytosis and internalization of membrane-bound annexin V. TMEM16E is internalized during this process but returns to the plasma membrane. |
