Structure and Function of a Mycobacterial NHEJ DNA Repair Polymerase [PDF]

open access: yes, 2006
Non homologous end-joining (NHEJ)-mediated repair of DNA double-strand breaks in prokaryotes requires Ku and a specific multidomain DNA ligase (LigD).

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

open access: yesFEBS Open Bio, EarlyView.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

New Aspects of HECT-E3 Ligases in Cell Senescence and Cell Death of Plants

open access: yesPlants, 2019
Plant cells undergo massive orderly changes in structure, biochemistry, and gene expression during cell senescence. These changes cannot be distinguished from the hydrolysis/degradation function controlled by the ubiquitination pathway, autophagy, and ...

Role of the ubiquitin-selective CDC-48/UFD-1/NPL-4 chaperone in DNA replication [PDF]

open access: yes, 2012
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.

Making ends meet: repairing breaks in bacterial DNA by non-homologous end-joining. [PDF]

open access: yes, 2006
DNA double-strand breaks (DSBs) are one of the most dangerous forms of DNA lesion that can result in genomic instability and cell death. Therefore cells have developed elaborate DSB-repair pathways to maintain the integrity of genomic DNA.

RRP9 Promotes Esophageal Squamous Cell Carcinoma Progression through E2F1 Transcriptional Regulation of CDK1

open access: yesAdvanced Biology, EarlyView.
The study reveals that RRP9 is abnormally highly expressed in ESCC tissues and is closely associated with poor prognosis in patients. Furthermore, it is found that RRP9 promotes ESCC progression through enhancing the E2F1‐mediated transcriptional regulation of CDK1.

The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery

open access: yesNature Communications, 2017
SUMO and ubiquitin are key signal transducers in several cellular processes including the DNA-damage response. Here the authors describe a method for selective enrichment of ubiquitin substrates for E3 ligases from complex cellular proteomes and identify

Subcellular organization of UBE3A in human cerebral cortex. [PDF]

open access: yes, 2018
BackgroundLoss of UBE3A causes Angelman syndrome, whereas excess UBE3A activity appears to increase the risk for autism. Despite this powerful association with neurodevelopmental disorders, there is still much to be learned about UBE3A, including its ...
