  2. Porcupine


Porcupine (Porc) protein may be involved in secretion or ER transport, as Wingless is retained in the ER in porcupine mutant Drosophila embryos. In C. elegans, the porcupine homolog mom-1 has a similar function in promoting secretion of the Wnt protein Mom-2. Porcupine has some homology to a family of o-acyl transferases and may be involved in lipid modification of Wnt proteins. A special form of monounsaturated palmitoylation has been detected on a serine residue in the Wnt protein and could be mediated by porc as well. The human Porcupine gene is implicated in a genetic disease, Focal dermal hypoplasia. Porcupine, encodes a multipass transmembrane ER protein, which is required for normal distribution of Wg in embryos. Porc stimulates the processing of Wg when expressed in Drosophila cells in vitro and is also necessary for the localization of Drosophila Wnt-3 on the axon tracts of the embryonic central nervous system.

    IWP-2 Inhibitor 99.51%
    IWP-2 is an inhibitor of Wnt processing and secretion with an IC50 of 27 nM. IWP-2 targets the membrane-bound O-acyltransferase porcupine (Porcn) and thus preventing a crucial Wnt ligand palmitoylation. IWP-2 is also an ATP-competitive CK1δ inhibitor with an IC50 of 40 nM for the gatekeeper mutant M82FCK1δ[1][2].
