Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Resistin and adenylyl cyclase-associated protein 1 (CAP1) regulate the expression of genes related to insulin resistance in BNL CL.2 mouse liver cells

Data in Brief, 2019
Resistin is an adipokine produced in white adipose tissue that is thought to modulate insulin sensitivity in peripheral tissues (such as liver, skeletal muscle or adipose tissue). Human and murine resistin molecules share only about 60% sequence homology.

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

pH sensing via bicarbonate-regulated ‘soluble’ adenylyl cyclase (sAC)

Frontiers in Physiology, 2013
Soluble adenylyl cyclase (sAC) is a source of the second messenger cyclic adenosine 3',5' monophosphate (cAMP). sAC is directly regulated by bicarbonate (HCO3-) ions. In living cells, HCO3- ions are in nearly instantaneous equilibrium with carbon

The importin‐alpha superfamily engages in ethylene signaling by shuttling ETHYLENE INSENSITIVE 2 from the endoplasmic reticulum to the nucleus

The FEBS Journal, EarlyView.
The plant hormone ethylene regulates plant growth, ripening, senescence, and stress responses. The hormonal signal transmission, from receptors at the ER membrane to the transcriptional regulators in the nucleus, is still not completely understood.

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

The FEBS Journal, EarlyView.
The urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as

Evidence for functional pre-coupled complexes of receptor heteromers and adenylyl cyclase

Nature Communications, 2018
It is unclear whether GPCRs, G proteins and adenylyl cyclase (AC) associate through random collisions or defined pre-coupling mechanisms. Using a peptide-based approach, the authors show that heteromers of adenosine A2A and dopamine D2 receptors form pre-

Sphingosylphosphorylcholine Antagonizes Proton-Sensing Ovarian Cancer G-Protein-Coupled Receptor 1 (OGR1)-Mediated Inositol Phosphate Production and cAMP Accumulation

Journal of Pharmacological Sciences, 2005
Ovarian cancer G-protein-coupled receptor 1 (OGR1), previously proposed as a receptor for sphingosylphosphorylcholine (SPC), has recently been identified as a proton-sensing or extracellular pH-responsive G-protein-coupled receptor stimulating inositol ...

Control of glutamate release by complexes of adenosine and cannabinoid receptors

BMC Biology, 2020
Background It has been hypothesized that heteromers of adenosine A2A receptors (A2AR) and cannabinoid CB1 receptors (CB1R) localized in glutamatergic nerve terminals mediate the integration of adenosine and endocannabinoid signaling involved in the ...
