Allele

Symbol: Il2rg^tm1Wjl
Name: targeted mutation 1, Warren J Leonard
MGI accession ID: MGI:1857455
Generation method: Targeted
Attributes: Null/Knockout
Synonyms: [KO]gammac; CD132^-; gammac^-; gc^-; Il2rg^tm1Wjll; IL2Rgamma^null
Marker symbol: Il2rg
Marker name: interleukin 2 receptor, gamma chain
Marker synonyms: [g]c; Ab2-183; Cd132; CIDX; common cytokine receptor gamma chain; common gamma chain; gamma C receptor; gamma(c); gammaC; gc; IL-2RG; IMD4; P64; SCIDX; SCIDX1

Molecular note: A neomycin resistance cassette replaced part of exon 3 and all of exons 4 - 8 of the gene, resulting in the loss of most of the extracellular domain and all of the transmembrane and cytoplasmic domains of the protein.

Allele

Symbol: Gt(ROSA)26Sor^{em28(KRT18-ACE2)Mvw}
Name: endonuclease-mediated mutation 27, Micheal V Wiles
MGI accession ID: MGI:7432933
Generation method: Endonuclease-mediated
Attributes: Inserted expressed sequence; Humanized sequence; Epitope tag
Synonyms: RMCE[K18-HuACE2]
Marker symbol: Gt(ROSA)26Sor
Marker name: gene trap ROSA 26, Philippe Soriano
Marker synonyms: beta geo; Gtrgeo26; Gtrosa26; R26; ROSA26; SETD5-AS1; Thumpd3as1
Chromosome: 6
Strain of origin: NOD.Cg-Prkdc^scid Il2rg^tm1Wjl/SzJ
Molecular note: CRISPR/cas9 genome editing and RMCE (recombinase-mediated cassette exchange) are utilized to insert a human keratin 18 promoter directing expression of the full length human ACE2with a C-terminal FLAG epitope tag into a modified Gt(ROSA)26Sor (NSG.RosaBxb-GT/GA) locus. The NOD.Cg-Prkdc Il2rg/SzJ (NSG)-derived zygotes carrying the Gt(ROSA)26Sor (RosaBxb-GT/GA) allele were previously targeted to insert a dual Bxb1 attP-site "safe harbor landing pad" in the first intron of Gt(ROSA)26Sor. The landing pad contains a 48 bp Bxb1 attP-GT sequence and a 48 bp Bxb1 attP-GA sequence separated by a 240 bp spacer of native Gt(ROSA)26Sor sequence. The DNA donor plasmid, carrying two heterologous attB sites and donor transgene, was then microinjected with Bxb1 integrase into the RMCE-ready zygotes (attP-GT/GA). This allele is similar to the em27 allele described in Low BE, et al Sci Rep 2022.
