Description générale

Axin1 contains two conserved domains, an N-terminal regulator of G-protein signaling (RGS) domain, and a C-terminal DIX domain. The C-terminal region of axin1 is important for homodimerization, whereas the central region binds β-catenin and GSK-3b.

Immunogène

synthetic peptide corresponding to amino acids 815-833 located near the C-terminal region of human axin1, conjugated to KLH. This sequence is identical in rat and mouse axin1 and highly conserved (83% identity) in human, rat, and mouse axin2.

Application

Immunohistochemistry was performed using rabbit anti-axin antibody to visualize Axin in the mouse developing cortex. Mouse brains had been previously harvested and fixed in 4% paraformaldhyde and cryoprotected in 20% sucrose. Axin was seen in the soma and axons of neurons.
Rabbit anti-axin1 (C-terminal region) antibody can be used at a concentration of 0.5-1μg/ml in western blot assays using HEK-293 cells expressing mouse axin1.

Actions biochimiques/physiologiques

Axin1 (axis inhibitor-1 or axin) functions as a negative regulator of Wnt signaling. Axin1 is known to associate with several members of the Wnt pathway such as β-catenin, glycogen synthase kinase-3b (GSK-3b), dishevelled (Dsh) and adenomatous polyposis coli (APC).
Axin1 (axis inhibitor-1, axin) enhances the phosphorylation of β-catenin by Glycogen synthase kinase 3 β (GSK-3b). Axin1 is involved in the degradation of β-catenin by acting as a scaffold to form a complex between β-catenin, adenomatous polyposis coli (APC) and GSK-3b thus, facilitating β-catenin phosphorylation by GSK-3b. Axin1 itself is phosphorylated and its activity regulated by GSK-3b. Axin1 phosphorylation is reduced by Wnt signaling, leading to decreased affinity of interaction of axin1 and β-catenin. This results in the release of β-catenin from the degradation complex and increased stability of β-catenin in the cell. Axin1 is destabilized by Wnt signaling and its levels in the cell are reduced. Axin isoform axin2 (conductin, axil) is 44% identical to Axin1 and appears to play a similar role to Axin1 in the Wnt signaling pathway.
