Cell autonomous regulation of multiple Dishevelled-dependent pathways by mammalian Nkd
Genetic studies have identified Drosophila Naked Cuticle (Nkd) as an antagonist of the canonical Wnt/β-catenin signaling pathway, but its mechanism of action remains obscure [Zeng, W., Wharton, K.Expand
Casein kinase iepsilon in the wnt pathway: regulation of beta-catenin function.
Wnt and its intracellular effector beta-catenin regulate developmental and oncogenic processes. Using expression cloning to identify novel components of the Wnt pathway, we isolated casein kinaseExpand
Bridging of β-catenin and glycogen synthase kinase-3β by Axin and inhibition of β-catenin-mediated transcription
Axin antagonizes the developmental effects of Wnt in vertebrates. We show here that Axin simultaneously binds two components of the Wnt pathway, β-catenin and its negative regulator glycogen synthaseExpand
Repressor roles for TCF-4 and Sfrp1 in Wnt signaling in breast cancer
Mutations in Wnt pathway genes are rare in human breast cancer, yet activation of the pathway is evident from the misolocalization of β-catenin. We searched for relationships in the expression of WntExpand
Identification of Two Isoforms of Mouse Neuropeptide Y-Y1 Receptor Generated by Alternative Splicing
Two cDNA clones homologous with human neuropeptide (NP) Y-Y1 receptor have been isolated from a mouse bone marrow cDNA library. One was thought to be the cognate of the human NPY-Y1 receptor, termedExpand
On the mechanism of cytosolic phospholipase A2 activation in CHO cells carrying somatostatin receptor: wortmannin-sensitive pathway to activate mitogen-activated protein kinase.
We examined the mechanism of arachidonate release induced by somatostatin-14 (SS14) in CHO-K1 cells overexpressing rat hippocampal somatostatin receptor SSTR4. SSTR4 couples to pertussis toxinExpand
Bridging of beta-catenin and glycogen synthase kinase-3beta by axin and inhibition of beta-catenin-mediated transcription.
Axin antagonizes the developmental effects of Wnt in vertebrates. We show here that Axin simultaneously binds two components of the Wnt pathway, beta-catenin and its negative regulator glycogenExpand
Casein kinase I « in the Wnt pathway : Regulation of b-catenin function
Wnt and its intracellular effector b-catenin regulate developmental and oncogenic processes. Using expression cloning to identify novel components of the Wnt pathway, we isolated casein kinase I«Expand
Functional coupling of SSTR4, a major hippocampal somatostatin receptor, to adenylate cyclase inhibition, arachidonate release and activation of the mitogen-activated protein kinase cascade.
Somatostatin has a modulatory role in regulating the membrane conductance in hippocampal neurons. To examine the signal transducing molecules involved in this process, we isolated the cDNA encodingExpand
Functional Domains of Axin
To understand the mechanism of how Axin acts as an inhibitory molecule in the Wnt pathway, we generated a series of mutated forms of Axin. From the binding experiments, we defined the domains of AxinExpand
