Germline Transmission:  Earliest citation of germline transmission: J:78223
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129S/SvEv
Allele Type:    Targeted (Inserted expressed sequence)
Mutation:    Nucleotide substitutions
Mutation detailsAn amino acid substitution was introduced into the saposin A domain of the gene utilizing a Cre/loxP system. Specifically, the mutation was introduced into exon 4 of the gene, changing the fourth cysteine in the saposin A domain to phenylalanine (C106F). This resulted in the loss of one of three conserved disulfide bonds within the protein. Animals carrying this allele produced stable mRNA of normal length. (J:78223)
