Targeted Allele Detail
Symbol: Cd22tm3Tft
Name: CD22 antigen; targeted mutation 3, Thomas F Tedder
MGI ID: MGI:3054888
Synonyms: Cd22delta1-2
Gene: Cd22  Location: Chr7:30865404-30880342 bp, - strand  Genetic Position: Chr7, 19.26 cM
Germline Transmission:  Earliest citation of germline transmission: J:92736
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsExons 3 and 4 were deleted following Cre-mediated excision of a floxed neo. A 3' mRNA splice junction of exon 3 was retained. Immunoblot and flow cytometry confirmed protein expression by B cells. Protein migrated as a 120 kDa fragment, the predicted size of the protein lacking two immunoglobulin-like domains. (J:92736)
