Exon 3 of this locus encodes the N terminus, including a portion of the extracellular ligand binding domain. A floxed neo-cassette was placed upstream of exon 3 and a single loxP site was placed downstream of exon 3. Mice carrying the targeted mutation in the germline were crossed with cre-transgenic mice to remove exon 3 and the neo-cassette, leaving in its place a single loxP site. Ligand crosslinking with 125I-TGFbeta to embryonic fibroblasts isolated from homozygotes confirms loss of protein expression. (J:141344)
