Cardiac - Interactions involving cardiac related proteins A beta-galactosidase complementation assay was used, where the two proteins of interest were each fused to the α (alpha) and ω (omega: from greek) complementary parts of beta-galactosidase. The α is a short N-terminal fragment and the ω is a long C-terminal fragment. To quentify the levels of protein expression, ω fusion proteins were fused to renilla luciferase (RL). The triple fusions allowed simultaneous measurements of beta-gal complementation versus expression levels, as measured by RL activity. rtmoon@u.washington.edu Nat. Cell Biol.

Most of frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. May be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues. Activation by Wnt5A stimulates PKC activity via a G-protein-dependent mechanism fzd4_human Frizzled-4 FZD4 FzE4 protein protein human Homo sapiens Human
