Germline Transmission:  Earliest citation of germline transmission: J:69408
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129/Sv
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsThe gene was disrupted by insertion of a PGK-neo cassette into exon 3 via homologous recombination. Absence of gene expression in homozygous mutant animals was verified by Northern and Western blot of liver RNA and proteins. (J:69408)
