Comparison of in vivo and in vitro Ipl1 phosphorylation sites in Sli15.

aSee Table 3 for phosphorylation site mapping data.bThis study.cNakajima et al. [26]; these sites represent all occurrences of the motif [KR]-X-[ST]-[ILVST] in Sli15.dAll verified in vivo phosphorylation sites present in the PhosphoGrid [50], [51] and Phosphopep databases [52] that have either K or R in the −2 position as required for potential Aurora B/Ipl1 phosphorylation, but without restricting the identity +1 residue.ePhosphorylated residue is shown in bold.fPossible in vivo target of a proline-directed protein kinase such as Slt2 or Cdc28 rather than Ipl1.
