Alpha‐2‐adrenoreceptor agonists as analgesic drugs in equine medicine

open access: yesEquine Veterinary Education, EarlyView.
Summary Managing pain in horses is challenging despite the availability of nonsteroidal anti‐inflammatory drugs, local anaesthetics, opioids and α2‐adrenoreceptor agonists. While α2‐agonists are widely used for sedation and restraint, their analgesic properties remain underutilised.

Allosteric activation of the nitric oxide receptor soluble guanylate cyclase mapped by cryo-electron microscopy. [PDF]

open access: yes, 2019
Soluble guanylate cyclase (sGC) is the primary receptor for nitric oxide (NO) in mammalian nitric oxide signaling. We determined structures of full-length Manduca sexta sGC in both inactive and active states using cryo-electron microscopy. NO and the sGC-

Smoothened adopts multiple active and inactive conformations capable of trafficking to the primary cilium. [PDF]

open access: yes, 2009
Activation of Hedgehog (Hh) signaling requires the transmembrane protein Smoothened (Smo), a member of the G-protein coupled receptor superfamily. In mammals, Smo translocates to the primary cilium upon binding of Hh ligands to their receptor, Patched ...

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

open access: yesThe 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

The complex of TRIP-Br1 and XIAP ubiquitinates and degrades multiple adenylyl cyclase isoforms

open access: yeseLife, 2017
Adenylyl cyclases (ACs) generate cAMP, a second messenger of utmost importance that regulates a vast array of biological processes in all kingdoms of life.

Funktionelle Charakterisierung von Adenylatzyklasen der Honigbiene Apis mellifera [PDF]

open access: yes, 2005
Adenylyl cyclases (ACs) are enzymes that synthesize the intracellular messenger adenosine 3',5'-cyclic monophosphate (cAMP). The physiological impact of ACs has been intensively investigated in the mammalian brain and in the fruitfly Drosophila ...

Co-Localization of p-CREB and p-NR1 in Spinothalamic Neurons in a Chronic Muscle Pain Model [PDF]

open access: yes, 2007
Activation of the cAMP pathway is an important mediator of chronic muscle pain. This study examined phosphorylation of the transcription factor cAMP-response-element-binding protein (p-CREB) and the NR1 subunit of the NMDA receptor (p-NR1) in the spinal ...

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

open access: yesThe 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 ...

Role of canonical and non-canonical cAMP sources in CRHR2α-dependent signaling.

open access: yesPLoS ONE
Hippocampal neurons exhibit activation of both the conventional transmembrane adenylyl cyclases (tmACs) and the non-canonical soluble adenylyl cyclase (sAC) as sources of cyclic AMP (cAMP). These two cAMP sources play crucial roles in mediating signaling

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

open access: yesThe 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.
