The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Role of the ubiquitin-selective CDC-48/UFD-1/NPL-4 chaperone in DNA replication [PDF]
Faithful transmission of genomic information requires tight spatiotemporal regulation of DNA replication factors. Posttranslational modifications, such as ubiquitylation, constitute a fast and effective mechanism to control such complex protein function.

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...

The role of HECT-type E3 ubiquitin ligases in inflammation
Homologous to the E6-AP Carboxyl Terminus (HECT)-type E3 ubiquitin ligases are key components of the ubiquitin-proteasome system (UPS) and play an important role in the regulation of inflammatory responses. Inflammation serves as a core defense mechanism

A conserved ubiquitin ligase of the nuclear envelope/endoplasmic reticulum that functions in both ER-associated and Mat a2 repressor degradation [PDF]
Substrate discrimination in the ubiquitin–proteasome system is believed to be dictated by specific combinations of ubiquitin–protein ligases (E3s) and ubiquitin-conjugating enzymes (E2s).

Casitas B-lineage lymphoma linker helix mutations found in myeloproliferative neoplasms affect conformation [PDF]
Background: Casitas B-lineage lymphoma (Cbl or c-Cbl) is a RING ubiquitin ligase that negatively regulates protein tyrosine kinase (PTK) signalling. Phosphorylation of a conserved residue (Tyr371) on the linker helix region (LHR) between the substrate ...

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.
