Allosteric auto-inhibition and activation of the Nedd4 family E3 ligase Itch.
The Nedd4 family E3 ligases are key regulators of cell growth and proliferation and are often misregulated in human cancers and other diseases. The ligase activities of Nedd4 E3s are tightly controlled via auto-inhibition. However, the molecular mechanism underlying Nedd4 E3 auto-inhibition and activation is poorly understood. Here, we show that the WW domains proceeding the catalytic HECT doma...
متن کاملDifferential Domain Architecture Directs Nedd4 Family E3 Ligase Function
Nedd4-family E3 ubiquitin ligases regulate signaling in intracellular pathways that control cancer, blood pressure, iron metabolism, and inflammation. These E3 ligases are catalytically active, and share a highly conserved, modular architecture. How Nedd4 family members are differentially regulated, despite their high degree of homology, is unclear. A regulatory mechanism that maintains an inac...
متن کاملITCH E3 ligase in ATM network
Ataxia Telangiectasia Mutated (ATM) kinase is a central regulator of the DNA damage response and its loss of function leads to the development of Ataxia Telangiectasia, a rare genetic disorder characterized by several features among which cerebellar neuron degeneration which causes ataxia, telangiectasia, immune system abnormalities, higher predisposition to lymphoma and leukaemia development a...
متن کاملE3 Ligase Nedd4 Promotes Axon Branching by Downregulating PTEN
Regulated protein degradation via the ubiquitin-proteasome system (UPS) plays a central role in building synaptic connections, yet little is known about either which specific UPS components are involved or UPS targets in neurons. We report that inhibiting the UPS in developing Xenopus retinal ganglion cells (RGCs) with a dominant-negative ubiquitin mutant decreases terminal branching in the tec...
متن کاملTranslational regulation of the expression of the ubiquitin E3 ligase Nedd4–1 by mTORC1-dependent signaling
We found recently that mTORC1 regulates the biosynthesis of the ubiquitin E3 ligase Nedd4-1, but not the close homolog Nedd4-2. This regulatory process plays a key role in promoting neurite growth in neurons of the mammalian central nervous system. The molecular mechanism underlying this rather specific regulation likely involves a pyrimidine-rich sequence stretch near the putative transcriptio...
