Germline Transmission:  Earliest citation of germline transmission: J:58367
Parent Cell Line:  RW-4 (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted (Conditional ready, No functional change)
Mutation:    Insertion
Mutation detailsInsertion of a PGK-neomycin resistance cassette introduced two loxP sites flanking exon 3 and the inserted cassette. Exon 3 contains phosphorylation target serine/threonine residues. Future deletion of exon 3 with cre recombinase would result in mRNA whose exons 2 and 4 are connected in frame. (J:58367)
