Generation of Taf7l^D144G knockin mice. (A) Schematic of mouse Taf7l gene structure, targeting vector, and various alleles. Taf7l consists of 13 exons. Only the first nine exons are shown in rectangles. Exons 10 to 13 are not shown. The asterisk in Exon 4 denotes the point mutation. PGK-Neo encodes a neomycin selection marker. HyTK enables positive selection with hygromycin (not used) and negative selection with ganciclovir. pOG231 expresses Cre recombinase. (B) Genotyping of Taf7l alleles. (C) Sequencing of the wild type and Taf7l^D144G alleles. (D) qRT-PCR analysis of the Taf7l transcript in wild type and Taf7l^D144G/Y testes from 3-month-old mice. n.s.: nonsignificant, by Student’s t-test. (E) Western blot analysis of TAF7L in 3-month-old wild type and Taf7l^D144G/Y testes. GAPDH serves as a loading control.
