Fatty acylation of wnt proteins
WebFatty acid desaturation is crucial for the labeling of multiple WNT proteins, as A939572, an inhibitor of stearoyl-CoA desaturase (SCD), which converts palmitate to palmitoleate, blocked WNT lipidation ( Fig. 1 G and Fig. S2 ). IWP2, a PORCN inhibitor structurally distinct from WNT974 (, ), also inhibited WNT palmitoleation. Webthat the trans fat did not alter general protein secretion (Fig. 3C).Thisresultalsosuggeststhat,indeed,atransFA,andnota cis FA produced from an unknown cis-trans isomerase, was affixed onto the WNT protein. We also note that WNT974 inhibited trans fatty acylation of WNT protein, confirming the role of PORCN in this biochemical …
Fatty acylation of wnt proteins
Did you know?
WebStudies of Wnt fatty acylation in cell-based labeling assays revealed that lipid modification of Wnt proteins occurs in two steps. Stearoyl-CoA desaturase first converts palmitoyl-CoA into palmitoleoyl-CoA, which is then utilized as a substrate by the Wnt acyltransferase Porcupine (PORCN) 2 ( 7. ). WebWnt proteins carry several stretches of highly charged amino acids and have a predicted isoelectric point of nearly 9, which, in combination with multiple glycosylation events, …
WebAug 20, 2024 · Protein fatty acylation is an important cotranslational or posttranslational modification of proteins, in which various fatty acids are covalently attached to … WebMay 24, 2016 · Although the vast majority of fatty acylated proteins are intracellular or transmembrane proteins, fatty acids can also be attached to secreted proteins. The MBOAT (membrane bound O-acyl transferase) family catalyzes attachment of palmitate to hedgehog proteins, palmitoleoylate to Wnt proteins, and octanoate to ghrelin.
