Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

ChemBioChem, EarlyView.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

Gαq signalling from endosomes: A new conundrum

British Journal of Pharmacology, EarlyView., 2023
Abstract G‐protein‐coupled receptors (GPCRs) constitute the largest family of membrane receptors, and are involved in the transmission of a variety of extracellular stimuli such as hormones, neurotransmitters, light and odorants into intracellular responses.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]

, 2016
RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

Stochastic single-gene auto-regulation [PDF]

, 2011
A detailed stochastic model of single-gene auto-regulation is established and its solutions are explored when mRNA dynamics is fast compared with protein dynamics and in the opposite regime. The model includes all the sources of randomness that are intrinsic to the auto-regulation process and it considers both transcriptional and post transcriptional ...

Regulation of phospholipase C-delta by GTP-binding proteins-rhoA as an inhibitory modulator

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1998
The regulation of Phospholipase C (PLC)delta activity remains obscure. These studies show that PLCdelta1 activity is significantly enhanced by both guanosine thiotriphosphate (GTPgammaS) and Clostridium botulinum exoenzyme C3 (C3) but not by aluminium fluoride.

Methods for Controlling Small GTPase Activity

ChemBioChem, Accepted Article.
Small GTPases comprise a diverse class of signaling proteins in mammalian cells and regulate a variety of cellular processes such as cell growth, cell movement, vesicle formation, and nuclear transport. Due to their involvement in critical cellular pathways, changes in the activation state of small GTPases due to genetic mutations or alterations in ...

Microtubule-severing enzymes: From cellular functions to molecular mechanism. [PDF]

, 2018
Microtubule-severing enzymes generate internal breaks in microtubules. They are conserved in eukaryotes from ciliates to mammals, and their function is important in diverse cellular processes ranging from cilia biogenesis to cell division, phototropism ...

Curvature-sensing and generation by membrane proteins: a review [PDF]

Soft Matter 21, 3922-3940 (2025)
Membrane proteins are crucial in regulating biomembrane shapes and controlling the dynamic changes in membrane morphology during essential cellular processes. These proteins can localize to regions with their preferred curvatures (curvature sensing) and induce localized membrane curvature.

Small GTP-binding protein PdRanBP regulates vascular tissue development in poplar

BMC Genetics, 2016
Previous research has demonstrated that ectopic expression of Ran-binding protein (RanBP) in Arabidopsis results in more axillary buds and reduced apical dominance compared to WT plants. However, the function of RanBP in poplar, which has very typical secondary growth, remains unclear.

Chromenone derivatives as CRM1 Inhibitors for Targeting Glioblastoma

ChemBioChem, Accepted Article.
Glioblastoma (GBM) is one of the most aggressive and deadly cancers. Due to the complexity and redundancy within signaling networks in GBM, targeted inhibitors of specific pathways have shown only limited success. The nuclear export receptor Chromosome Region Maintenance 1 (CRM1) has recently emerged as a promising therapeutic target, as its inhibition
