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

open access: yesFrontiers 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

PACAP induces FSHβ gene expression via EPAC. [PDF]

open access: yes, 2019
Gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are heterodimers of a common α subunit and unique β subunits. Regulation of their levels, primarily by GnRH, is critical for reproductive function.

Use of a cAMP BRET Sensor to Characterize a Novel Regulation of cAMP by the Sphingosine 1-Phosphate/G13 Pathway [PDF]

open access: yes, 2007
Regulation of intracellular cyclic adenosine 3',5'-monophosphate (cAMP) is integral in mediating cell growth, cell differentiation, and immune responses in hematopoietic cells. To facilitate studies of cAMP regulation we developed a BRET (bioluminescence

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

open access: yesNature 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-

A Study on the Origin of Peroxisomes: Possibility of Actinobacteria Symbiosis [PDF]

open access: yes, 2008
The origin of peroxisomes as having developed from the endoplasmic reticulum (ER) was proposed on the basis of the similarity between some peroxisomal proteins and ER proteins, and the localization of some peroxisomal proteins on the ER.

Functional Non‐Nucleoside Adenylyl Cyclase Inhibitors

open access: yesChemical Biology & Drug Design, 2014
In this study, we describe the synthesis of novel functional non‐nucleoside adenylyl cyclase inhibitors, which can be easily modified with thiol containing biomolecules such as tumour targeting structures. The linkage between inhibitor and biomolecule contains cleavable bonds to enable efficient intracellular delivery in the reductive milieu of the ...

Krisanaklan Reduces Intestinal Anion and Fluid Secretion Through Inhibition of Na+/K+‐ATPase and K+ Channel Activity

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
Krisanaklan reduces CFTR‐dependent intestinal chloride and fluid secretion by inhibiting the Na+,K+‐ATPase and K+ channels in epithelial cells. Consequently, this natural, plant‐derived product may limit secretory diarrhea caused by a diverse array of microbial pathogens. However, by dissipating the transmembrane Na+ gradient, Krisanaklan also inhibits

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

open access: yesJournal 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 ...

Mutational mapping of RAS-responsive domains of the Saccharomyces cerevisiae adenylyl cyclase [PDF]

open access: yes, 1990
Large deletion and small insertion mutations in the adenylyl cyclase gene of Saccharomyces cerevisiae were used to map regions required for activation by RAS protein in vitro.
