α-Kap alignment. Complete ORFs from the various α-Kaps were aligned by using the clustalv package of programs (27) and high gap penalties. ∗ and • below the alignment indicate identities and similarities, respectively among all α-Kaps. The boxes indicate the most recent definition of the Arm repeats (12, 13), and the horizontal arrows indicate the HEAT motifs. The PID (protein identification) numbers of each sequence are indicated at the beginning of the alignment. Note that the Caenorhabditis elegans α-Kap, a composite of several expressed sequence tags, has a considerably longer N terminus, which may be an artifact.
