we showed that a truncated rat mlc1f/3f gene lacking exon 1 and the first 6.3 kilobases of the intron separating exons 1 and 2 produced rat mlc3f mrna in a developmentally regulated manner after introduction into myogenic mouse cells , thus demonstrating in vivo the presence of a functional promoter associated with exon 2 .
