Targeted Allele Detail
Symbol: Kcnmb4tm1Rwa
Name: potassium large conductance calcium-activated channel, subfamily M, beta member 4; targeted mutation 1, Richard W Aldrich
MGI ID: MGI:3611890
Synonyms: Beta4-, BK-Beta4 null
Gene: Kcnmb4  Location: Chr10:116417861-116473878 bp, - strand  Genetic Position: Chr10, 64.73 cM, cytoband D2
Germline Transmission:  Earliest citation of germline transmission: J:103931
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 1 was replaced with an eGFP-SV40-neo cassette. Elimination of the exon results in the loss of approximately half of the protein-coding region, including the first transmembrane domain. Northern blot did not detect transcript of the wild-type, but did detect transcript using an eGFP probe. (J:103931)
