Arrangement of IFITM gene clusters in the tammar, opossum, human and mouse. Arrows indicate the direction of transcription. The paler bar for IFITMA in the opossum indicates that there is not enough information available to determine whether the contig containing IFITMA is continuous with the cluster containing IFITMB1, -B2 and −5.
