Strain Information

BRC No.RBRC00462
TypeTargeted Mutation CongenicCartagena
SpeciesMus musculus
Strain nameB6.Cg-Mak<tm1Yshk>/YshkRbrc
Former Common nameMAK Knockout mice B6
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strainC57BL/6NJcl
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Dr. Shinkai at Kyoto University. A neo cassette was transferred into TT2 ES cells to replace exons 5-8 in the Mak gene. The mutant mice were backcrossed to C57BL/6NJcl for 9 times.
Strain descriptionB6.Cg-Mak<tm1Yshk>. Mak, male germ cell-associated kinase gene expresses specifically in testicular germ cells. Mak deficient mice show no gross abnormalities, and most of the mice were fertile. However, the litter size derived homozygous mutant males and their sperm motility in vitro were mildly reduced compared to those of normal mice. This strain is useful for elucidation of the function of Mak gene in spermatogenesis.
Colony maintenanceSibling mating.Homozygous male are fertile, but exhibit slight reduction in litter size and sperm motility in vitro.
