Figure 4. PLK4 phosphorylates serine and threonine residues in a proline consensus.

Figure 4.

(A) Centrinone-down-regulated phosphorylation site sequence conservation using IceLogo [66] reveals extensive Pro enrichment around the site of phosphorylation. (B) Frequency of novel Pro-directed motifs (blue), the known consensus sequence for Aurora A (RR[pS/pT]), or the acidic residue-rich motifs of PLK1 ([D/E]x[pS/pT]Φ, where Φ represents hydrophobic Y/F/I/L/V residues and x is any amino acid), PLK2 ([D/E]xx[pS/pT], PLK3 ([pS/pT]x[D/E]) or the classic hydrophobic PLK4 consensus ([pS/pT]ΦΦ) across all centrinone-down-regulated phosphorylation sites.
