Gene: Smarca4  Location: Chr9:21527465-21615526 bp, + strand  Genetic Position: Chr9, 7.84 cM
Germline Transmission:  Earliest citation of germline transmission: J:66861
Parent Cell Line:  CT129 (ES Cell)
Strain of Origin:  129S/Sv
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA neomycin selection cassette replaced sequence encoding part of the DNA-dependent ATPase domain. The deleted region encoded helicase motif 1, which contains the ATP binding site, and helicase motif 1a. The allele was expected to encode a chimeric protein, though while Northern blot analysis identified transcripts containing both endogenous and neo transgene elements, protein was undetected by Western blot analysis.
