Strain development Developed by Drs. Ryoji Yao, Tadashi Yamamoto, and Tetsuo Noda, Japanese Foundation for Cancer Research Cancer Institute in 1999. An exon of Cnot7 subcloned the 18-kb genomic DNA fragment, was replaced by the insertion of a LacZ and a floxed neo cassette. The floxed neo cassette was excised in this strain. This strain originated on a B6;129 background.  
Strain description B6;129S4-Cnot7<tm1Tno>. Cnot7 gene (CCR4-NOT transcription complex. subunit 7) is essential for spermatogenesis. Cnot7 deficient male mice are sterile owing to oligo-astheno-teratozoospermia, impaired sperm motility, unsynchronized spermatid maturation, and Sertoli cell abnormalities. This knockout mouse strain is a powerful tool for understanding the mechanisms underlying spermatogenesis.  
Colony maintenance Heterozygote x Wild-type
Homozygous mutant males are sterile.
