Targeted Allele Detail
Symbol: Cd44tm1Mak
Name: CD44 antigen; targeted mutation 1, Tak W Mak
MGI ID: MGI:2181292
Synonyms: CD44-
Gene: Cd44  Location: Chr2:102811141-102901665 bp, - strand  Genetic Position: Chr2, 54.13 cM
Germline Transmission:  Earliest citation of germline transmission: J:72658
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe 3' portion of exon 2 and all of exon 3 were replaced by the insertion of a neomycin resistance cassette. The deleted region encodes part of the invariant amino terminus, common to all isoforms. A lack of protein surface expression was observed in spleen, lymph node, and thymus cells via flow cytometry.
