Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

Tankyrase‐2 regulates adipocyte differentiation through AMPK/mTOR signaling
Tankyrase 2 (TNKS2), a PARP family member, underpins adipocyte differentiation. TNKS2 controls LKB1 protein level, and consequently, the activity of the mTOR/AMPK system and adipocyte differentiation through a layered process. Pharmacological inhibition of TNKS2 leaves other PARPs and DNA repair active and therefore represents a novel target in ...

A guide to transcriptional cyclin‐dependent kinases in cancer
Transcriptional cyclin‐dependent‐kinases (tCDKs) facilitate gene expression by promoting RNA polymerase II (RNAPII) progression through discrete phases of the transcription cycle. Aberrant tCDK activity is detectable in different human cancers, thereby contributing to de‐regulated gene expression programs that drive oncogenic phenotypes.

As we age, cells gradually accumulate damage, which can contribute to disease and neurodegeneration. This review explores how two cellular recycling processes, mitophagy and nucleophagy, remove damaged mitochondria and nuclear material, respectively, to maintain cell health and long‐term neuronal homeostasis.

Dimerization of human PARP15 is required for NAD+ binding and automodification
This study provides an integrated structural model of human PARP15. Biophysical, enzymatic, and cell‐based analyses identify the dimer as the active oligomeric state capable of binding the substrate NAD+. A co‐crystal structure with a non‐hydrolyzable substrate analog BAD reveals the molecular basis for the dimerization requirement.
