Purine Nucleotide Availability Regulates mTORC1 Activity through the Rheb GTPase

Cell Reports, 2017
Pharmacologic agents that interfere with nucleotide metabolism constitute an important class of anticancer agents. Recent studies have demonstrated that mTOR complex 1 (mTORC1) inhibitors suppress de novo biosynthesis of pyrimidine and purine nucleotides.

Protein Farnesylation Takes Part in Arabidopsis Seed Development

Frontiers in Plant Science, 2021
Protein farnesylation is a post-translational modification regulated by the ERA1 (Enhanced Response to ABA 1) gene encoding the β-subunit of the protein farnesyltransferase in Arabidopsis.

Investigation of LKB1 Ser⁴³¹ phosphorylation and Cys⁴³³ farnesylation using mouse knockin analysis reveals an unexpected role of prenylation in regulating AMPK activity [PDF]

, 2014
The LKB1 tumour suppressor protein kinase functions to activate two isoforms of AMPK (AMP-activated protein kinase) and 12 members of the AMPK-related family of protein kinases. The highly conserved C-terminal residues of LKB1 are phosphorylated (Ser(431)

Purification of the CaaX-modified, dynamin-related large GTPase hGBP1 by coexpression with farnesyltransferase[S]

Journal of Lipid Research, 2010
Over a hundred proteins in eukaryotic cells carry a C-terminal CaaX box sequence, which targets them for posttranslational isoprenylation of the cysteine residue.

Protein farnesylation is upregulated in Alzheimer’s human brains and neuron-specific suppression of farnesyltransferase mitigates pathogenic processes in Alzheimer’s model mice

Acta Neuropathologica Communications, 2021
The pathogenic mechanisms underlying the development of Alzheimer’s disease (AD) remain elusive and to date there are no effective prevention or treatment for AD.

Mechanisms of A-Type Lamin Targeting to Nuclear Ruptures Are Disrupted in LMNA- and BANF1-Associated Progerias

Cells, 2022
Mutations in the genes LMNA and BANF1 can lead to accelerated aging syndromes called progeria. The protein products of these genes, A-type lamins and BAF, respectively, are nuclear envelope (NE) proteins that interact and participate in various cellular ...

Farnesylation of the Transducin G Protein Gamma Subunit Is a Prerequisite for Its Ciliary Targeting in Rod Photoreceptors

Frontiers in Molecular Neuroscience, 2018
Primary cilia are microtubule-based organelles, which protrude from the plasma membrane and receive a wide range of extracellular signals. Various cilia use G protein-coupled receptors (GPCRs) for the detection of these signals.

Zoledronic acid treatment impairs protein geranyl-geranylation for biological effects in prostatic cells [PDF]

, 2006
BACKGROUND: Nitrogen-containing bisphosphonates (N-BPs) have been designed to inhibit osteoclast-mediated bone resorption. However, it is now accepted that part of their anti-tumor activities is related to interference with the mevalonate pathway ...

Assessing the efficacy of protein farnesyltransferase inhibitors in mouse models of progeria

Journal of Lipid Research, 2010
Hutchinson-Gilford progeria syndrome (HGPS) is caused by the accumulation of a farnesylated form of prelamin A (progerin). Previously, we showed that blocking protein farnesylation with a farnesyltransferase inhibitor (FTI) ameliorates the disease ...

Farnesyltransferase inhibitors and human malignant pleural mesothelioma: a first-step comparative translational study. [PDF]

, 2005
It is known that the potential clinical use of farnesyltransferase inhibitors (FTI) could be expanded to include cancers harboring activated receptor tyrosine kinases.
