Directed evolution approaches for optogenetic tool development.

Biochemical Society transactions

Jang J, Woolley GA.
PMID: 34783342
Biochem Soc Trans. 2021 Nov 16; doi: 10.1042/BST20210700. Epub 2021 Nov 16.

Photoswitchable proteins enable specific molecular events occurring in complex biological settings to be probed in a rapid and reversible fashion. Recent progress in the development of photoswitchable proteins as components of optogenetic tools has been greatly facilitated by directed...

To export, or not to export: how nuclear export factor variants resolve Piwi's dilemma.

Biochemical Society transactions

Wang S, Lu X, Qiu D, Yu Y.
PMID: 34643228
Biochem Soc Trans. 2021 Nov 01;49(5):2073-2079. doi: 10.1042/BST20201171.

Piwi-interacting RNAs (piRNAs) defend animal gonads by guiding PIWI-clade Argonaute proteins to silence transposons. The nuclear Piwi/piRNA complexes confer transcriptional repression of transposons, which is accompanied with heterochromatin formation at target loci. On the other hand, piRNA clusters, genomic...

Targeting small GTPases and their downstream pathways with intracellular macromolecule binders to define alternative therapeutic strategies in cancer.

Biochemical Society transactions

Sorbara M, Bery N.
PMID: 34623375
Biochem Soc Trans. 2021 Nov 01;49(5):2021-2035. doi: 10.1042/BST20201059.

The RAS superfamily of small GTPases regulates major physiological cellular processes. Mutation or deregulation of these small GTPases, their regulators and/or their effectors are associated with many diseases including cancer. Hence, targeting these classes of proteins is an important...

Combinatorial biosynthesis for the generation of new-to-nature peptide antimicrobials.

Biochemical Society transactions

Ruijne F, Kuipers OP.
PMID: 33439248
Biochem Soc Trans. 2021 Feb 26;49(1):203-215. doi: 10.1042/BST20200425.

Natural peptide products are a valuable source of important therapeutic agents, including antibiotics, antivirals and crop protection agents. Aided by an increased understanding of structure-activity relationships of these complex molecules and the biosynthetic machineries that produce them, it has...

Towards structure-focused glycoproteomics.

Biochemical Society transactions

Chernykh A, Kawahara R, Thaysen-Andersen M.
PMID: 33439247
Biochem Soc Trans. 2021 Feb 26;49(1):161-186. doi: 10.1042/BST20200222.

Facilitated by advances in the separation sciences, mass spectrometry and informatics, glycoproteomics, the analysis of intact glycopeptides at scale, has recently matured enabling new insights into the complex glycoproteome. While diverse quantitative glycoproteomics strategies capable of mapping monosaccharide compositions...

TOP2B's contributions to transcription.

Biochemical Society transactions

Austin CA, Cowell IG, Khazeem MM, Lok D, Ng HT.
PMID: 34747992
Biochem Soc Trans. 2021 Nov 08; doi: 10.1042/BST20200454. Epub 2021 Nov 08.

Transcription is regulated and mediated by multiprotein complexes in a chromatin context. Transcription causes changes in DNA topology which is modulated by DNA topoisomerases, enzymes that catalyse changes in DNA topology via transient breaking and re-joining of one or...

Live-cell visualization of cytochrome c: a tool to explore apoptosis.

Biochemical Society transactions

Pessoa J.
PMID: 34747968
Biochem Soc Trans. 2021 Nov 08; doi: 10.1042/BST20211028. Epub 2021 Nov 08.

Apoptosis dysfunction is associated with several malignancies, including cancer and autoimmune diseases. Apoptosis restoration could be an attractive therapeutic approach to those diseases. Mitochondrial outer membrane permeabilization is regarded as the point of no return in the 'classical' apoptosis...

YbeY, éminence grise of ribosome biogenesis.

Biochemical Society transactions

Liao Z, Schelcher C, Smirnov A.
PMID: 33929506
Biochem Soc Trans. 2021 Apr 30;49(2):727-745. doi: 10.1042/BST20200669.

YbeY is an ultraconserved small protein belonging to the unique heritage shared by most existing bacteria and eukaryotic organelles of bacterial origin, mitochondria and chloroplasts. Studied in more than a dozen of evolutionarily distant species, YbeY is invariably critical...

What's in a mass?.

Biochemical Society transactions

Calvete JJ, Sanz L, Mora-Obando D, Lomonte B, Tanaka-Azevedo AM, de Morais-Zani K, Sant'Anna SS, Caldeira CAS.
PMID: 33929513
Biochem Soc Trans. 2021 Apr 30;49(2):1027-1037. doi: 10.1042/BST20210288.

This short essay pretends to make the reader reflect on the concept of biological mass and on the added value that the determination of this molecular property of a protein brings to the interpretation of evolutionary and translational snake...

Heterochromatin and Polycomb as regulators of haematopoiesis.

Biochemical Society transactions

Keenan CR.
PMID: 33929498
Biochem Soc Trans. 2021 Apr 30;49(2):805-814. doi: 10.1042/BST20200737.

Haematopoiesis is the process by which multipotent haematopoietic stem cells are transformed into each and every type of terminally differentiated blood cell. Epigenetic silencing is critical for this process by regulating the transcription of cell-cycle genes critical for self-renewal...

Structural insights into glucocorticoid receptor function.

Biochemical Society transactions

Frank F, Ortlund EA, Liu X.
PMID: 34709368
Biochem Soc Trans. 2021 Nov 01;49(5):2333-2343. doi: 10.1042/BST20210419.

The glucocorticoid receptor (GR) is a steroid hormone-activated transcription factor that binds to various glucocorticoid response elements to up- or down- regulate the transcription of thousands of genes involved in metabolism, development, stress and inflammatory responses. GR consists of...
