A Ubiquitin-like Protein Unleashes Ubiquitin Ligases [PDF]
Modification of cullin-RING ubiquitin ligases by the ubiquitin-like molecule Nedd8 promotes substrate ubiquitination. A crystal structure of a cullin modified by Nedd8 recently reported in Cell (Duda et al., 2008) and a biochemical study in Molecular Cell (Saha and Deshaies, 2008) reveal the dramatic impact on the ligase machinery by conjugation of ...

G3BP1 modulates SPOP to promote prostate tumorigenesis
Speckle-type POZ protein (SPOP), a Cullin 3-based ubiquitin ligase (CUL3SPOP), acts as a prostate-specific tumor suppressor. Loss-of-function mutations in SPOP occur in 10% of primary prostate cancer with a high Gleason grade and poor prognosis. However,

Cbl-c ubiquitin ligase activity is increased via the interaction of its RING finger domain with a LIM domain of the paxillin homolog, Hic 5. [PDF]
Cbl proteins (Cbl, Cbl-b and Cbl-c) are ubiquitin ligases that are critical regulators of tyrosine kinase signaling. In this study we identify a new Cbl-c interacting protein, Hydrogen peroxide Induced Construct 5 (Hic-5).

Stealing the spotlight: CUL4-DDB1 ubiquitin ligase docks WD40-repeat proteins to destroy
Recent investigation of Cullin 4 (CUL4) has ushered this class of multiprotein ubiquitin E3 ligases to center stage as critical regulators of diverse processes including cell cycle regulation, developmental patterning, DNA replication, DNA damage and ...

The HIV1 protein Vpr acts to enhance constitutive DCAF1-dependent UNG2 turnover. [PDF]
The HIV1 protein Vpr assembles with and acts through an ubiquitin ligase complex that includes DDB1 and cullin 4 (CRL4) to cause G2 cell cycle arrest and to promote degradation of both uracil DNA glycosylase 2 (UNG2) and single-strand selective mono ...

The AAA+ ATPase/ubiquitin ligase mysterin stabilizes cytoplasmic lipid droplets
Mysterin, also known as RNF213, is an intracellular protein that forms large toroidal oligomers. Mysterin was originally identified in genetic studies of moyamoya disease (MMD), a rare cerebrovascular disorder of unknown etiology. While mysterin is known
