Lipidated Stapled Peptides Targeting the Acyl Binding Protein UNC119

The acyl‐binding UNC119 proteins mediate the activation and transport of various N‐myristoylated proteins. In particular, UNC119a plays a crucial role in the completion of cytokinesis. Herein, we report the use of a lipidated peptide originating from the UNC119 binding partner Gnat1 as the basis for...

Sumario:The acyl‐binding UNC119 proteins mediate the activation and transport of various N‐myristoylated proteins. In particular, UNC119a plays a crucial role in the completion of cytokinesis. Herein, we report the use of a lipidated peptide originating from the UNC119 binding partner Gnat1 as the basis for the design of lipidated, stabilized α‐helical peptides that target UNC119a. By using the hydrocarbon peptide‐stapling approach, cell‐permeable binders of UNC119a were generated that induced the accumulation of cytokinetic and binucleated cells; this suggests UNC119a as a potential target for the inhibition of cytokinesis.
