Structural basis of K11/K48-branched ubiquitin chain recognition by the human 26S proteasome [PDF]
Beyond the canonical K48-linked homotypic polyubiquitination for proteasome-targeted proteolysis, K11/K48-branched ubiquitin (Ub) chains are involved in fast-tracking protein turnover during cell cycle progression and proteotoxic stress.

The deubiquitinating enzyme Cezanne stabilizes BRCA1 by counteracting APC/C and Ube2S-dependent Lys11-linked ubiquitination. [PDF]
The breast and ovarian tumor suppressor BRCA1 is a cell cycle-regulated protein and tumors with reduced BRCA1 protein level may share molecular features of BRCA1-mutant tumor and respond to PARPi therapy. Here, we identify that BRCA1 protein stability is

RNF114 and RNF166 exemplify reader-writer E3 ligases that extend K11 polyubiquitin onto sites of MARUbylation [PDF]
Ubiquitin (Ub) cooperates with other post-translational modifications to provide a tiered opportunity for protein regulation. Deltex E3 ligases were previously implicated in ubiquitylation of ADP-ribose (ADPr)-containing macromolecules in vitro ...

The Design and Construction of K11: A Novel α-Helical Antimicrobial Peptide [PDF]
Amphipathic α-helical antimicrobial peptides comprise a class of broad-spectrum agents that are used against pathogens. We designed a series of antimicrobial peptides, CP-P (KWKSFIKKLTSKFLHLAKKF) and its derivatives, and determined their minimum ...

RNF167 mediates atypical ubiquitylation and degradation of RLRs via two distinct proteolytic pathways [PDF]
The precise regulation of the RIG-I-like receptors (RLRs)-mediated type I interferon (IFN-I) activation is crucial in antiviral immunity and maintaining host immune homeostasis in the meantime.

TRIM21‐Mediated K11‐Linked Ubiquitination of ID1 Suppresses Tumorigenesis and Promotes Cuproptosis in Esophageal Squamous Cell Carcinoma [PDF]
Inhibitor of DNA binding 1 (ID1) is a key transcriptional regulator involved in the development of various cancers, including esophageal squamous cell carcinoma (ESCC). However, the mechanisms regulating ID1 ubiquitination in ESCC are not well understood.

Objectives Gastrointestinal stromal tumors (GISTs) carrying different KIT exon 11 (KIT-11) mutations exhibit varying prognoses and responses to Imatinib. Herein, we aimed to determine whether computed tomography (CT) radiomics can accurately stratify KIT-

Identification of Bacteriophage K11 Genomic Promoters for K11 RNA Polymerase [PDF]
Only one natural promoter that interacts with bacteriophage K11 RNA polymerase has so far been identified. To identify more, in the present study restriction fragments of the phage genome were individually assayed for transcription activity in vitro. The K11 genome was digested with two 4-bp-recognizing restriction enzymes, and the fragments cloned in ...
