Strain: W;WIAR-Izumo1em1Osb

Symbol: W;WIAR-Izumo1em1Osb
Strain: W;WIAR-Izumo1em1
Substrain: Osb
RGD ID: 329845586
Citation ID: RRID:RGD_329845586
Ontology ID: RS:0005267
Alleles: Izumo1em1Osb
Also Known As: NBRP Rat No: 0862; W;WIAR-Izumo1^[em1Osb]
Type: mutant
Available Source: National BioResource Project for the Rat in Japan
Origination: Osaka University
Description: Izumo1 KO strain was established by CRISPR/Cas9 system using inbred WIAR (RGD:2304222) (SLC, Inc.). sgRNA:GGTGGCTGCAATAAAGACTT, PAM sequence:TGG. A 7-bp deletion(CTTTGGA)after start codon (Met) in exon2 of Izumo1 gene was detected. After establishment of WIAR background KO rats, this strain was mated with Slc:Wistar (RGD:2314928), hence this mutant is in mix background.Izumo1-deficient male rats are infertile. In female rats, no specific phenotype is observed.
Coat Color: albino
Last Known Status: Cryopreserved Sperm (as of 2023-12-28)
