A schematic drawing of the tree exon rat histamine H4 receptor gene and the partial sequence of the two isolated H4 isoforms. (A) The E1, E2 and E3 exons are indicated and the deleted region in the shorter isoform is marked in green. (B) A part of the cloned sequences are aligned and identical accept for the 164 bp deletion in the shorter cDNA (gap marked in green). The potential new stop codon for the frame shifted shorter message is marked in red.
