SOXB1 genetic regulation in the developing testes

Absence of Sox3 in mice only results in subtle phenotype, presumably due to the rescue effects from the family members, SOXB1, which consist of Sox1, Sox2 and Sox3. Obvious defect in Sox3-KO mice is seen only in the testes where Sox1 and Sox2 are not co-expressed. The genetic dysregulation underlying this testis defects is unknown. We also hypothesize that this genetic dysregulation can be rescued by the other SOXB1 members.
