Sh3yl1^tm1Syb

The targeting vector used to create the Sh3yl1tm1a(KOMP)Wtsi allele was used to create this knockout allele. The L1L2_Bact_P cassette was inserted at position 30939123 of Chromosome 12 upstream of exon 5 (Build GRCm38). The cassette is composed of an FRT site followed by lacZ sequence and a loxP site. This first loxP site is followed by a neomycin resistance gene under the control of the human beta-actin promoter, SV40 polyA, a second FRT site and a second loxP site. A third loxP site is inserted downstream of exon 5 at position 30939920. Exon 5 is thus flanked by loxP sites. A "conditional ready" (floxed) allele can be created by flp recombinase expression in mice carrying this allele. Subsequent cre expression results in a knockout mouse. If cre expression occurs without flp expression, a reporter knockout mouse will be created.
