{"doi":"10.1126/sciadv.adq3374","title":"A genetically encoded actuator boosts L-type calcium channel function in diverse physiological settings","abstract":"L-type Ca 2+ channels (Ca V 1.2/1.3) convey influx of calcium ions that orchestrate a bevy of biological responses including muscle contraction, neuronal function, and gene transcription. Deficits in Ca V 1 function play a vital role in cardiac and neurodevelopmental disorders. Here, we develop a genetically encoded enhancer of Ca V 1.2/1.3 channels (GeeC L ) to manipulate Ca 2+ entry in distinct physiological settings. We functionalized a nanobody that targets the Ca V complex by attaching a minimal effector domain from an endogenous Ca V modulator—leucine-rich repeat containing protein 10 (Lrrc10). In cardiomyocytes, GeeC L selectively increased L-type current amplitude. In neurons in vitro and in vivo, GeeC L augmented excitation-transcription (E-T) coupling. In all, GeeC L represents a powerful strategy to boost Ca V 1.2/1.3 function and lays the groundwork to illuminate insights on neuronal and cardiac physiology and disease.","journal":"Science Advances","year":2024,"id":443570,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":8,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9502,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1177992,"name":"Diego Scala Chavez","orcid":null,"position":1,"is_corresponding":false},{"id":929303,"name":"Srinidhi Jayaraman","orcid":null,"position":2,"is_corresponding":false},{"id":484272,"name":"Lin Yang","orcid":"0009-0005-6756-1683","position":3,"is_corresponding":false},{"id":1258187,"name":"Stefanie M.
