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 ...

Ubiquitination is a post-translational modification of proteins involved in a variety of cellular processes. Ubiquitination requires the sequential action of three enzymes: E1 (ubiquitin-activating enzymes), E2 (ubiquitin-conjugating enzymes), and E3 (ubiquitin ligases).

Adaptors as the regulators of HECT ubiquitin ligases [PDF]
The HECT (homologous to E6AP C-terminus) ubiquitin ligases (E3s) are a small family of highly conserved enzymes involved in diverse cellular functions and pathological conditions. Characterised by a C-terminal HECT domain that accepts ubiquitin from E2 ubiquitin conjugating enzymes, these E3s regulate key signalling pathways.

E3 ubiquitin ligases are important components of the ubiquitin protease system. This family includes many proteins, which can catalyze the ubiquitination of a variety of protein substrates and promote the degradation of them by the proteasome system ...

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

Self‐regulating ubiquitin ligases [PDF]
Occasional auto‐modification of ubiquitin ligases typically leads to their proteasomal destruction, but new findings published in The EMBO Journal now show that in the case of Rsp5/Nedd4, auto‐ubiquitylation instead triggers oligomerization and concomitant reduction of ligase activity. This novel mechanism therefore creates silenced ligases that remain

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 ...
