A Ubiquitin-like Protein Unleashes Ubiquitin Ligases [PDF]
Cell, 2008 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 ...

Role of Nse1 Subunit of SMC5/6 Complex as a Ubiquitin Ligase
Cells, 2022 Structural Maintenance of Chromosomes (SMC) complexes are important for many aspects of the chromosomal organization. Unlike cohesin and condensin, the SMC5/6 complex contains a variant RING domain carried by its Nse1 subunit.

G3BP1 modulates SPOP to promote prostate tumorigenesis
Molecular & Cellular Oncology, 2022 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,

Tau affects P53 function and cell fate during the DNA damage response [PDF]
Communications Biology 3, 245 (2020), 2020 Cells are constantly exposed to DNA damaging insults. To protect the organism, cells developed a complex molecular response coordinated by P53, the master regulator of DNA repair, cell division and cell fate. DNA damage accumulation and abnormal cell fate decision may represent a pathomechanism shared by aging-associated disorders such as cancer and ...

The SCF Ubiquitin Ligase [PDF]
Molecular Cell, 2002 The SCF E3 ubiquitin ligases select specific proteins for ubiquitination (and typically destruction) by coupling variable adaptor (F box) proteins that bind protein substrates to a conserved catalytic engine containing a cullin, Cul1, and the Rbx1/Roc1 RING finger protein.

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]
PLoS ONE, 2012 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).

The HIV1 protein Vpr acts to enhance constitutive DCAF1-dependent UNG2 turnover. [PDF]
PLoS ONE, 2012 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 ...

SUMO chain-induced dimerization activates RNF4 [PDF]
, 2014 Dimeric RING E3 ligases interact with protein substrates and conformationally restrain the ubiquitin-E2-conjugating enzyme thioester complex such that it is primed for catalysis.
