... presence of alternative splicing around the 5¢-end of exon 6 of Meis2 and Meis3 was tested by RT-PCR. The positions of molecular mass markers are shown to the left, and the size in base pairs of the ... However, the activity of the full-length Meis1a was not tested, and on the basis of our work we expect that its activity would be inhibited by the conserved Hth...
