Ligand binding to the ectodomain of the insulin-like growth factor receptor destabilises an autoinhibitory inter-subunit interaction, which allows the transmembrane domains to associate and the intracellular regions to autophosphorylate.
Inducible degradation of the insulin/insulin-like growth factor-1 receptor shows that a doubling in lifespan is possible even at extremely old ages in an organism.
Zinc metalloproteinase Papp-aa-mediated Igfbp5 proteolysis functions as a [Ca2+]-regulated molecular switch linking IGF signaling to epithelial cell proliferation and bone calcification.
A powerful sequencing approach is used to elucidate the genetic basis of a complex organismal trait, and members of the irld gene family that affect starvation resistance are identified.
The IGF2 mRNA binding protein-2/IMP2, overexpressed in many common cancers, drives cancer cell proliferation by increasing the abundance of IGF2 and the oncogene HMGA1, which controls a network of effectors that enhance IGF2 action.
Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.
