经典Wnt信号通路

Wnt pathways are involved in the control of gene expression, cell behavior, cell adhesion, and cell polarity. The Canonical (β-Catenin-Dependent) Wnt Signaling pathway is the best studied of the Wnt pathways and is highly conserved through evolution.

Sino Biological offers a comprehensive set of tools for research on canonical Wnt signaling pathway, including proteins, antibodies (mouse & rabbit MAbs, rabbit PAbs), ELISA kits, and ORF cDNA clone.

经典Wnt信号通路 Background

Wnt pathways are involved in the control of gene expression, cell behavior, cell adhesion, and cell polarity. The Canonical (β-Catenin-Dependent) Wnt Signaling pathway is the best studied of the Wnt pathways and is highly conserved through evolution. In this pathway, Wnt signaling inhibits the degradation of β-catenin, which can regulate transcription of a number of genes. Wnt signaling is activated via ligation of Wnt proteins to their respective dimeric cell surface receptors composed of the seven transmembrane frizzled proteins and the LRP5/6. Upon ligation to their receptors, the cytoplasmic protein disheveled (Dvl) is recruited, phosphorylated and activated. Activation of Dvl induces the dissociation of GSK-3β from Axin and leads to the inhibition of GSK-3β. Next, the phosphorylation and degradation of β-catenin is inhibited as a result of the inactivation of the "destruction complex". Subsequently, stabilized β-catenin translocates into the nucleus leading to changes in different target gene expressions.
