The transmembrane adhesion receptor, E-cadherin, not only facilitates cell-cell adhesion but modulates cytokinesis by impeding cortical F-actin flow and inhibiting actomyosin contractility. In the C. elegans zygote, newly established cell-cell interfaces following cytokinesis lack E-cadherin/HMR-1 (Padmanabhan et al., 2017b). The mechanisms responsible for the spatial exclusion of HMR-1, however remain elusive. Here, we show that HMR-1 is actively prevented from entering the cytokinetic furrow zone during early embryonic divisions in C. elegans . The compact alignment of unbranched F-actin filaments polymerized by the formin/CYK-1 restricts HMR-1 from entering the ingressing furrow. This corralling phenomenon depends on the physical association between HMR-1 and F-actin mediated via the β- and α- catenins, HMP-2 and HMP-1, respectively. Our findings reveal a previously unknown reciprocal regulatory relationship between cell adhesion and cell division machineries, ensuring the precise orchestration of the cytokinesis during embryonic development.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2023,"id":414871,"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":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9575,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1196786,"name":"Megha Rai","orcid":"0000-0002-0613-5227","position":1,"is_corresponding":false},{"id":1196787,"name":"Anup Padmanabhan","orcid":"0000-0001-6007-6929","position":2,"is_corresponding":false},{"id":1197106,"name":"Debodyuti Mondal","orcid":null,"position":0,"is_corresponding":true}],"reference_count":58,"raw_metadata":null,"created_at":"2026-07-19T01:22:08.814145Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
