mRNA splice variants of mouse ICAM-4gene.

Depiction of the 2 mRNA species of ICAM-4. Vertical bars represent the 3 exons with the size of each exon shown above the bar. Sizes of the first and third exons indicate the number of bases in coding sequence only. Intron 1, containing 113 bases, is spliced out in both isoforms, while intron 2 is excluded in ICAM-4 and included in ICAM-4S mRNA.
