A Micropeptide Component of the OGDH Complex Modulates ATP Production in the TCA Cycle
This study identified a mitochondrial micropeptide encoded by a non‐canonical open reading frame (alt‐ORF) within the CTSB gene. This micropeptide named APPM (ATP production‐promoting micropeptide) is a novel component of the OGDHc complex in the TCA cycle. APPM localizes to the inner mitochondrial membrane and directly binds to OGDH, the E1 subunit of

Fzd7 Restrains Pink1‐Dependent Mitophagy in Suture Stem Cells to Maintain Cranial Suture Patency
How suture stem cells fail to preserve cranial suture patency remains incompletely understood. Integrated single‐cell and high‐resolution spatial transcriptomic analyses identify reduced Fzd7 expression in Prrx1+ suture stem cells as an early feature of craniosynostosis.

Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

Selective Modulation of OTUB1 Noncanonical Function via a bioPhosTAC Strategy
This work positions the versatile performance of the peptide‐based bioPhosTAC platform for dissecting phosphorylation‐dependent biology and expanding the scope of induced‐proximity technologies. We demonstrated that selective manipulation of a tyrosine phosphorylation site is sufficient to propagate coordinated cellular consequences.

RSF1‐Dependent PAR Turnover Promotes 53BP1 Liquid Condensate Formation at DNA Damage Sites
At sites of DNA damage, RSF1 recruits PARG to accelerate PAR turnover, triggering a switch from PAR‐driven condensates to 53BP1 condensates. This condensate transition enables p53‐dependent gene transcription and coordinates the DNA damage response.

SLC8A1 deficiency in colorectal cancer cells increases intracellular calcium signaling, promoting the secretion of ANXA2‐enriched small extracellular vesicles. These vesicles reprogram tumor‐associated macrophages towards an M2 phenotype, which in turn fosters a tumor microenvironment conducive to radioresistance and is associated with poor patient ...
