{"doi":"10.1093/genetics/140.4.1339","title":"A screen for modifiers of Deformed function in Drosophila.","abstract":"<jats:title>Abstract</jats:title>\n               <jats:p>Proteins produced by the homeotic genes of the Hox family assign different identifies to cells on the anterior/posterior axis. Relatively little is known about the signalling pathways that modulate their activities or the factors with which they interact to assign specific segmental identifies. To identify genes that might encode such functions, we performed a screen for second site mutations that reduce the viability of animals carrying hypomorphic mutant alleles of the Drosophila homeotic locus, Deformed. Genes mapping to six complementation groups on the third chromosome were isolated as modifiers of Deformed function. Products of two of these genes, sallimus and moira, have been previously proposed as homeotic activators since they suppress the dominant adult phenotype of Polycomb mutants. Mutations in hedgehog, which encodes secreted signalling proteins, were also isolated as Deformed loss-of-function enhancers. Hedgehog mutant alleles also suppress the Polycomb phenotype. Mutations were also isolated in a few genes that interact with Deformed but not with Polycomb, indicating that the screen identified genes that are not general homeotic activators. Two of these genes, cap 'n' collar and defaced, have defects in embryonic head development that are similar to defects seen in loss of function Deformed mutants.</jats:p>","journal":"Genetics","year":1995,"id":44512,"datarank":1.47616026413403,"base_score":3.4965075614664802,"endowment":3.4965075614664802,"self_citation_contribution":0.5244761342199721,"citation_network_contribution":0.9516841299140578,"self_endowment_contribution":0.5244761342199721,"citer_contribution":0.9516841299140578,"corpus_percentile":null,"corpus_rank":null,"citation_count":32,"citer_count":24,"citers_with_citation_signal":22,"citers_with_endowment":22,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":209436,"name":"G Gellon","orcid":null,"position":1,"is_corresponding":false},{"id":209437,"name":"N McGinnis","orcid":null,"position":2,"is_corresponding":false},{"id":209438,"name":"W McGinnis","orcid":null,"position":3,"is_corresponding":false},{"id":209435,"name":"K W Harding","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":3.4965075614664802,"endowment":3.4965075614664802,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"7498774","pmcid":"PMC1206698","openalex_id":"https://openalex.org/W1901767187","authors":[],"funders":[{"funder_name":"NICHD NIH HHS","grant_id":"HD-30368","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"GM-07499","title":null}],"total_grants":2,"fwci":1.3552,"citation_percentile":0.80272902,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":1},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2017,"count":1},{"year":2024,"count":1}],"oa_status":"bronze","license":"https://academic.oup.com/journals/pages/open_access/funder_policies/chorus/standard_publication_model","oa_locations":[{"url":"https://academic.oup.com/genetics/article-pdf/140/4/1339/34606403/genetics1339.pdf","host_type":"journal"},{"url":"https://academic.oup.com/genetics/article-pdf/140/4/1339/34606403/genetics1339.pdf","host_type":"publisher"},{"url":"http://academic.oup.com/genetics/article-pdf/140/4/1339/34606403/genetics1339.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1093/genetics/140.4.1339","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/7498774","host_type":"repository"}],"fields_of_study":["Developmental Biology and Gene Regulation","Chromosomal and Genetic Variations","Epigenetics and DNA Methylation","Animals","Chromosome Mapping","Crosses, Genetic","DNA-Binding Proteins","Drosophila Proteins","Drosophila melanogaster","Female","Gene Expression Regulation, Developmental","Genes, Dominant","Genes, Lethal","Genetic Complementation Test","Head","Hedgehog Proteins","Homeodomain Proteins","Male","Morphogenesis","Phenotype","Polycomb Repressive Complex 1","Proteins","Suppression, Genetic","Transcription Factors"],"mesh_terms":["Animals","Chromosome Mapping","Crosses, Genetic","DNA-Binding Proteins","Drosophila melanogaster","Female","Genes, Dominant","Genes, Lethal","Genetic Complementation Test","Head","Male","Morphogenesis","Phenotype","Proteins","Suppression, Genetic","Transcription Factors","Homeodomain Proteins","Gene Expression Regulation, Developmental","Drosophila Proteins","Hedgehog Proteins","Polycomb Repressive Complex 1"],"keywords":["Homeotic gene","Biology","Genetics","Hox gene","Phenotype","Mutant","Gene","Complementation","Ultrabithorax","Haploinsufficiency","Homeobox","Locus (genetics)","Loss function","Enhancer","Genetic screen","Allele","Transcription factor"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-01T06:53:14.105034Z","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":[]}
