Targeted Allele Detail
Symbol: Mtnr1atm1Rep
Name: melatonin receptor 1A; targeted mutation 1, Steven M Reppert
MGI ID: MGI:2450160
Synonyms: MT1-, MT1 KO
Gene: Mtnr1a  Location: Chr8:45069137-45088506 bp, + strand  Genetic Position: Chr8, 24.95 cM
Germline Transmission:  Earliest citation of germline transmission: J:41859
Parent Cell Line:  J1 (ES Cell)
Strain of Origin:  129S4/SvJae
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 1 was replaced with a neomycin selection cassette inserted by homologous recombination. The deleted region encoded the 5' untranslated region and the first cytoplasmic loop. Autoradiography showed an absence of melatonin binding in sections of homozygous mutant brains, indicating complete functional ablation. (J:41859)
