The coding region was replaced with one containing a A to C substitution in exon 4 resulting in the substitution of alanine for aspartic acid at position 266 (D266A). This mutation prevents SMAD2 and SMAD3 activation but does not affect interacts with Acvrl1. RT-PCR analysis on spleen and liver was used to confirm the expression of the modified transcript.
