Palmitoylation motif
Web1 day ago · S-Palmitoylation is catalyzed by DHHC palmitoyltransferases, which are transmembrane proteins and exhibit a catalytic domain with a core motif DHHC (Asp-His-His-Cys) in the cytosolic region; DHHC enzymes target both cytosolic proteins and the cytosolic domain of transmembrane proteins [9]. WebDec 30, 2015 · Mutations at both palmitoylation site and the KIKK motif abolish the ability of oncogenic KRAS4A to induce leukemia in mice. Conclusions: Our studies suggest that therapies targeting RAS palmitoylation may also be effective in treating KRAS4A associated malignancies and that interfering the KIKK membrane-targeting motif would …
