Adenylyl cyclase Rv1625c of Mycobacterium tuberculosis: a progenitor of mammalian adenylyl cyclases [PDF]

The EMBO Journal, 2001
The gene Rv1625c from Mycobacterium tuberculosis encodes a membrane-anchored adenylyl cyclase corresponding to exactly one-half of a mammalian adenylyl cyclase. An engineered, soluble form of Rv1625c was expressed in Escherichia coli. It formed a homodimeric cyclase with two catalytic centers. Amino acid mutations predicted to affect catalysis resulted

Innate and learned odor-guided behaviors utilize distinct molecular signaling pathways in a shared dopaminergic circuit

Cell Reports, 2023
Summary: Odor-based learning and innate odor-driven behavior have been hypothesized to require separate neuronal circuitry. Contrary to this notion, innate behavior and olfactory learning were recently shown to share circuitry that includes the ...

l-DOPA-induced dyskinesia in hemiparkinsonian rats is associated with up-regulation of adenylyl cyclase type V/VI and increased GABA release in the substantia nigra reticulata

Neurobiology of Disease, 2011
l-DOPA treatment induces abnormal involuntary movements (AIMs) in Parkinson's patients and experimental animals. We examined the relationship between the development of AIMs (dyskinesia) and changes in [3H]-GABA release and cAMP signaling in ...

Inhibitors of membranous adenylyl cyclases [PDF]

Trends in Pharmacological Sciences, 2012
Membranous adenylyl cyclases (mACs) constitute a family of nine isoforms with different expression patterns. Studies with mAC gene knockout mice provide evidence for the notion that AC isoforms play distinct (patho)physiological roles. Consequently, there is substantial interest in the development of isoform-selective mAC inhibitors.

GTPγS Regulation of a 12-Transmembrane Guanylyl Cyclase Is Retained after Mutation to an Adenylyl Cyclase [PDF]

, 2001
DdGCA is a Dictyostelium guanylyl cyclase with a topology typical for mammalian adenylyl cyclases containing 12 transmembrane-spanning regions and two cyclase domain.

Assessing potency and binding kinetics of soluble adenylyl cyclase (sAC) inhibitors to maximize therapeutic potential

Frontiers in Physiology, 2022
In mammalian cells, 10 different adenylyl cyclases produce the ubiquitous second messenger, cyclic adenosine monophosphate (cAMP). Amongst these cAMP-generating enzymes, bicarbonate (HCO3−)-regulated soluble adenylyl cyclase (sAC; ADCY10) is uniquely ...

Adenylyl cyclases in the digestive system [PDF]

Cellular Signalling, 2014
Adenylyl cyclases (ACs) are a group of widely distributed enzymes whose functions are very diverse. There are nine known transmembrane AC isoforms activated by Gαs. Each has its own pattern of expression in the digestive system and differential regulation of function by Ca(2+) and other intracellular signals.

Rhodopsin-cyclases for photocontrol of cGMP/cAMP and 2.3 Å structure of the adenylyl cyclase domain

Nature Communications, 2018
Cyclic AMP and cGMP orchestrate a variety of cellular responses. Here, authors characterize the cGMP producing rhodopsin-guanylyl cyclase from C. anguillulae and derived adenylyl cyclase by a biochemical and structural approach which demonstrates the ...

Identification of essential residues for binding and activation in the human 5-HT7(a) receptor by molecular modeling and site-directed mutagenesis

Frontiers in Behavioral Neuroscience, 2015
The human 5-HT7 receptor is expressed in both the central nervous system and peripheral tissues and is a potential drug target in behavioral and psychiatric disorders.We examined molecular determinants of ligand binding and G protein activation by the ...

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

Advanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet
