Gene: Defb23em2MlitDefb26em2Mlit (defensin beta 23, defensin beta 26; CRISPR/Cas9 induced mutant2, Mlit) Rattus norvegicus
Symbol: Defb23em2MlitDefb26em2Mlit
Name: defensin beta 23, defensin beta 26; CRISPR/Cas9 induced mutant2, Mlit
RGD ID: 38599014
Description: CRISPR/Cas9 system was used to generate this double-gene knockout. The Slc:SD zygotes were injected with sgRNAs that containing 4 sgRNAs (5 ng/ml each) targeting 2 adjacent sites (target sites 1 and 2) of each of the 2 genes. The resulting mutations are 317 bp (Defb23) and 380 bp (Defb26) fragments which were deleted in the Defb23/Defb26 double-mutant strain.
ASSOCIATED WITH decreased litter size; decreased sperm progressive motility; impaired sperm capacitation
