The F-box and U-box E3 ubiquitin ligase decoy library is a powerful tool for the functional characterization of redundant E3 ubiquitin ligases, like MAC3A and MAC3B, novel circadian clock regulators.

CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

Arrestin-related trafficking adaptors (ARTs) undergo a K63 linked di-ubiquitin modification to promote Rsp5 E3 ligase recruitment and enhance cargo protein ubiquitination.

RNF213 is a giant E3 ligase with a dynein-like core and a unique ubiquitination mechanism that proceeds in a RING-independent manner and is linked with the Moyamoya disease.

Structural studies reveal the mechanism by which a HECT E3 ubiquitin ligase carries out E2-to-E3-to-substrate ubiquitin transfer and prioritizes target lysines for ubiquitination.

Engineered E3 ubiquitin ligases are utilized to elucidate mechanisms underlying ubiquitin regulation of membrane proteins, and to achieve robust post-translational functional knockdown of ion channels.

E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.

Human cullin-RING ligases are buffered to a much greater extent than had been previously appreciated, and the roles of ubiquitin chain extension enzymes are far more nuanced at physiological concentrations.

DDB1, a component of the ubiquitin proteasome system, plays a role in both hematopoietic and embryonic stem cell self-renewal and differentiation.

Control of lipoprotein receptor protein levels at synapses by the E3 ubiquitin ligase IDOL is shown to be important for the plasticity of neuronal dendrites in vitro and learning and memory in mice.
