A calcium-inhibited Drosophila adenylyl cyclase

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2000
Mammals possess a family of transmembrane, G-protein-responsive adenylyl cyclase isoforms (tmACs) encoded by distinct genes differing in their patterns of expression and modes of biochemical regulation. Our previous work confirmed that Drosophila melanogaster also possesses a family of tmAC isoforms defining the fly as a suitable genetic model for ...

Nucleotidyl cyclase activity of particulate guanylyl cyclase A: comparison with particulate guanylyl cyclases E and F, soluble guanylyl cyclase and bacterial adenylyl cyclases CyaA and edema factor. [PDF]

PLoS ONE, 2013
Guanylyl cyclases (GCs) regulate many physiological processes by catalyzing the synthesis of the second messenger cGMP. The GC family consists of seven particulate GCs (pGCs) and a nitric oxide-activated soluble GC (sGC).

Regulation and organization of adenylyl cyclases and cAMP.

Biochemical Journal, 2003
Adenylyl cyclases are a critically important family of multiply regulated signalling molecules. Their susceptibility to many modes of regulation allows them to integrate the activities of a variety of signalling pathways.

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains

The FEBS Journal, EarlyView.
Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.

Role of soluble adenylyl cyclase in mitochondria

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2014
The soluble adenylyl cyclase (sAC) catalyzes the conversion of ATP into cyclic AMP (cAMP). Recent studies have shed new light on the role of sAC localized in mitochondria and its product cAMP, which drives mitochondrial protein phosphorylation and regulation of the oxidative phosphorylation system and other metabolic enzymes, presumably through the ...

Allosteric modulation of protein kinase A in individuals affected by NLPD‐PKA, a neurodegenerative disease in which the PRKAR1B L50R variant is expressed

The FEBS Journal, EarlyView.
In healthy neurons, Protein kinase A (PKA) forms a tetrameric holoenzyme enabling precise allosteric regulation. We characterized a novel neurodegenerative disease, neuronal loss, and parkinsonism driven by PRKAR1B mutation (NLPD‐PKA), demonstrating disrupted holoenzyme assembly, reduced cooperativity, and increased catalytic subunit nuclear ...

Critical cysteines in the functional interaction of adenylyl cyclase isoform 6 with Gαs

FASEB BioAdvances, 2022
Activation of adenylyl cyclases (ACs) by G‐protein Gαs catalyzes the production of cyclic adenosine monophosphate (cAMP), a key second messenger that regulates diverse physiological responses.

Lipid regulation of adenylyl cyclase Rv1625c from Mycobacterium tuberculosis by its membrane‐domain receptor

The FEBS Journal, EarlyView.
The adenylyl cyclase (AC) Rv1625c from M. tuberculosis is a monomeric progenitor of the nine pseudoheterodimeric mammalian AC isoforms. The hexahelical membrane anchor of Rv1625c serves as an inhibitory receptor for fatty acids, particularly oleic acid. One ligand binds into each monomer of the active Rv1625c dimer.

Cyclic nucleotide signalling in malaria parasites. [PDF]

, 2017
The cyclic nucleotides 3', 5'-cyclic adenosine monophosphate (cAMP) and 3', 5'-cyclic guanosine monophosphate (cGMP) are intracellular messengers found in most animal cell types.
