Symbol: Ctla4tm1Shr
Name: cytotoxic T-lymphocyte-associated protein 4; targeted mutation 1, Arlene H Sharpe
MGI ID: MGI:2180668
Synonyms: Ctla4-, CTLA-4-
Gene: Ctla4  Location: Chr1:60948184-60954991 bp, + strand  Genetic Position: Chr1, 30.58 cM, cytoband C
Germline Transmission:  Earliest citation of germline transmission: J:30393
Parent Cell Line:  J1 (ES Cell)
Strain of Origin:  129S4/SvJae
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe insertion of a PGK-neo cassette replaced a 1.3 kb region containing exon 2 and a portion of exon 3. The deleted region encoded a IgV and part of a transmembrane domain. Fluorescence-activated cell sorting (FACS) analysis showed an absence of protein in splenocytes isolated from homozygous mutant mice. (J:30393)
