Schematic alignment of the two major SMAD4 transcripts and primers position. Human SMAD4 transcripts that encode full protein were aligned to distinguish between identical sequences in the coding part of the transcripts and 5’UTRs which discriminate them, in order to design appropriate primer pairs. Scheme refers to the mouse Smad4 transcripts, as human SMAD4 and mouse Smad4 transcripts are homologues and similar in length
