MBOAT family

Wnt proteins are also acylated. The Wnt3a protein is modified by thioester-linked palmitate at a conserved cysteine residue and also by an unsaturated fatty acid, palmitole-ic acid, which is oxyester-linked to a conserved serine residue (R. Takada, 2006). Porcupine (pore), a member of the MBOAT family, is required for the O-acylation of Wnt3a. It is not clear whether pore or another acyltransferase carries out the 5-acyl modification.
