ProNodal acts via FGFR3 to govern duration of Shh expression in the prechordal mesoderm.
Lausanne, Switzerland. In Development, Dec 2015
Exposure of prechordal mesoderm microcultures to Nodal-conditioned medium, the Nodal inhibitor CerS, or to an ALK4/5/7 inhibitor reveals that Nodal is required to maintain both Shh and Gsc expression, but whereas Gsc is largely maintained through canonical signalling, Nodal signals through a non-canonical route to maintain Shh.
Activin receptor signaling: a potential therapeutic target for osteoporosis.
Boston, United States. In Curr Mol Pharmacol, 2012
The binding of activins to activin type IIA (ActRIIA) or type IIB (ActRIIB) receptors induces the recruitment and phosphorylation of an activin type I receptor (ALK4 and/or ALK7), which then phosphorylates the Smad2 and Smad3 intracellular signaling proteins.
Activin receptor-like kinase and the insulin gene.
Kyoto, Japan. In Vitam Horm, 2010
Activins signaling, which is mediated by ALK4 and 7 together with ActRIIA and IIB, plays a critical role in glucose-stimulated insulin secretion, development/neogenesis, and glucose homeostatic control of pancreatic endocrine cells; the insulin gene is regulated by these signaling pathways via ALK7, which is a receptor for Activins AB and B and Nodal.
Modulation of activin and BMP signaling.
Los Angeles, United States. In Mol Cell Endocrinol, 2004
Here, we summarize recent advances in understanding the mode of action of activins and BMPs, focusing on our elucidation of the crystal structure of BMP-7 in complex with the extracellular domain (ECD) of the activin type II receptor and our identification of a binding site for activin on the type I receptor ALK4.
