Bex1, a novel interactor of the p75 neurotrophin receptor, links neurotrophin signaling to the cell cycle.
A screening for intracellular interactors of the p75 neurotrophin receptor (p75NTR) identified brain-expressed X-linked 1 (Bex1), a small adaptor-like protein of unknown function. Bex1 levels oscillated during the cell cycle, and preventing the normal cycling and downregulation of Bex1 in PC12 cells sustained cell proliferation under conditions of growth arrest, and inhibited neuronal different...
متن کاملRetrograde apoptotic signaling by the p75 neurotrophin receptor
Neurotrophins are target-derived factors necessary for mammalian nervous system development and maintenance. They are typically produced by neuronal target tissues and interact with their receptors at axonal endings. Therefore, locally generated neurotrophin signals must be conveyed from the axon back to the cell soma. Retrograde survival signaling by neurotrophin binding to Trk receptors has b...
متن کاملCD 271 (P75 neurotrophin receptor).
P75NTR (or CD271) is a member of the Tumor Necrosis Factor receptor (TNFR) super family of transmembrane proteins that share significant homology in their extracellular domains. Subsets of TNF receptors, including CD271, have a cytoplasmic death domain, although CD271 has unique intracellular structure and downstream signaling partners. CD271 is also differentiated from other members of the TNF...
متن کاملControl of the cell cycle by neurotrophins: lessons from the p75 neurotrophin receptor.
Although traditionally little attention has been paid to the interplay between neurotrophins and the cell cycle, a number of recent findings suggest an important role for these growth factors in the regulation of this aspect of the cellular physiology. In this article, we review the evidence from a number of studies that neurotrophins can influence cell cycle progression or mitotic cycle arrest...
متن کاملNuclear translocation of the p75 neurotrophin receptor cytoplasmic domain in response to neurotrophin binding.
The intracellular domain of the p75 neurotrophin receptor (p75ICD) can be released by gamma-secretase in response to the previous activation of alpha-secretase by phorbol esters. However, ligand-dependent release of p75ICD has yet to be described. We show here that nerve growth factor can induce the release of p75ICD and facilitate its translocation to the nucleus in a gamma-secretase-dependent...
