A Key Role for the Ubiquitin Ligase UBR4 in Myofiber Hypertrophy in Drosophila and Mice
Cell Reports, 2019 Summary: Skeletal muscle cell (myofiber) atrophy is a detrimental component of aging and cancer that primarily results from muscle protein degradation via the proteasome and ubiquitin ligases.

TRIM32 is an E3 ubiquitin ligase for dysbindin [PDF]
Human Molecular Genetics, 2009 Mutations in the gene encoding tripartite motif protein 32 (TRIM32) cause two seemingly diverse diseases: limb-girdle muscular dystrophy type 2H (LGMD2H) or sarcotubular myopathy (STM) and Bardet-Biedl syndrome type 11(BBS11). Although TRIM32 is involved in protein ubiquitination, its substrates and the molecular consequences of disease-causing ...

TRIM56 coiled-coil domain structure provides insights into its E3 ligase functions
Computational and Structural Biotechnology Journal, 2023 Protein ubiquitination is a post-translation modification mediated by E3 ubiquitin ligases. The RING domain E3 ligases are the largest family of E3 ubiquitin ligases, they act as a scaffold, bringing the E2-ubiquitin complex and its substrate together to

PEX2 is the E3 ubiquitin ligase required for pexophagy during starvation
Journal of Cell Biology, 2016 Sargent et al. identify the E3 ubiquitin ligase PEX2 as the causative agent of mammalian pexophagy. During amino acid starvation, PEX2 expression increases to ubiquitinate peroxisomal membrane proteins and signal peroxisome degradation by autophagy.

PINK1 phosphorylates ubiquitin to activate Parkin E3 ubiquitin ligase activity
Journal of Cell Biology, 2014 PINK1 phosphorylates ubiquitin, which then binds to Parkin and activates its E3 ligase activity, leading to induction of selective autophagy of damaged mitochondria.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
