Alignment and conserved motifs of Tektin proteins. Amino acid alignment of conserved regions of the Tektin protein complements from D. melanogaster (Dm), H. sapiens (Hs) and P. dumerilii (Pd) are shown grouped by the four Tektin classes: Tektin-1 or C, Tektin-2, Tektin 3/5, and Tektin-4 or A. The Tektin-3/5 class includes two human (3 and 5) and two Platynereis (3/5A and 3/5B) Tektins. Two pairs of alpha helices (Helix 1 and 2) are highlighted by pink boxes (compare to Fig. 1a). Conserved residues are color-coded using Aliview. The highly conserved nonapeptide motif between Helix 2A and Helix 2B [20] is highlighted above the alignment. Motifs identified in this study are highlighted below the alignment, and include a highly conserved motif (L . . R . . R . . . D/E L . . D) within the short regions between Helix 1A and 1B and Helix 2A and 2B, and a second conserved motif (L E . D . . . K . . . . . I D . . (.) C) within the C-terminus of Helix 1B and Helix 2B
