Salvage enzymes in nucleotide biosynthesis [PDF]

, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Transient disappearance of RAS mutant clones in plasma: A counterintuitive clinical use of EGFR inhibitors in RAS mutant metastatic colorectal cancer [PDF]

, 2019
Genomic studies performed through liquid biopsies widely elucidated the evolutionary trajectory of RAS mutant clones under the selective pressure of EGFR inhibitors in patients with wild type RAS primary colorectal tumors. Similarly, the disappearance of

Methods for Controlling Small GTPase Activity

ChemBioChem, EarlyView.
This concept highlights recent and emerging methods for controlling small GTPase activity, encompassing both small‐molecule‐based approaches and protein engineering strategies. The use of these approaches to advance the understanding of small GTPase function, current limitations, and future outlook is discussed.

ARC Expands the DAAM1 Microexon‐Mediated Actin–RHOA/ROCK Interplay

Cytoskeleton, EarlyView.
ABSTRACT Actin cytoskeleton and its dynamics play a crucial role in synaptic function, influencing dendritic spines' structural and functional plasticity. Recent findings unveiled the significance of alternative splicing of a neural‐specific microexon in DAAM1 in modulating actin's role in synaptic processes.

3.6.5.2 Small monomeric GTPases (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database [PDF]

, 2019
Small G-proteins, are a family of hydrolase enzymes that can bind and hydrolyze guanosine triphosphate (GTP). They are a type of G-protein found in the cytosol that are homologous to the alpha subunit of heterotrimeric G-proteins, but unlike the alpha ...

Gαs slow conformational transition upon GTP binding and a novel Gαs regulator

iScience, 2023
Summary: G proteins are major signaling partners for G protein-coupled receptors (GPCRs). Although stepwise structural changes during GPCR–G protein complex formation and guanosine diphosphate (GDP) release have been reported, no information is available

Mutant mitochondrial elongation factor G1 and combined oxidative phosphorylation deficiency [PDF]

, 2004
Although most components of the mitochondrial translation apparatus are encoded by nuclear genes, all known molecular defects associated with impaired mitochondrial translation are due to mutations in mitochondrial DNA.

Mechanical unloading is accompanied by reverse metabolic remodelling in the failing heart: Identification of a novel citraconate‐mediated pathway

European Journal of Heart Failure, EarlyView.
Aims Although functional recovery of the failing heart with left ventricular assist device (LVAD) unloading can occur, the underpinning mechanism is unclear. We aimed to characterize the effect of myocardial biochemical effect of LVAD support in vivo and in vitro.

Characterisation of ERK distribution and activity in rat pheochromocytoma cells : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Molecular Biology at Massey University [PDF]

, 1998
Nerve growth factor (NGF) binds to the NGF receptor, TrkA, at the tips of nerve cell axons, sending a signal that prevents programmed cell death and causes survival, growth, and differentiation of the nerve cell.
