Evolutionary site versus motif conservation. Representative sequence alignments of one ModSite for the chromosome-associated kinesin KIF4A [O95239_(T799, S801, T803)] with indicated site (purple) and motif conservation (yellow and green). This ModSite is a predicted substrate of Aurora B. The combination of site and motif conservation of T799 indicates this as the site most likely phosphorylated by Aurora B relative to the other ambiguous sites in this identifier. Abbreviations for the amino acids are as follows: A, Ala; C, Cys; D, Asp; E, Glu; F, Phe; I, Ile; K, Lys; L, Leu; N, Asn; P, Pro; R, Arg; S, Ser; T, Thr; and Y, Tyr.
