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

Mitochondrial control of ciliary gene expression and structure in striatal neurons
The Journal of Physiology, EarlyView.Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.

Psychostimulant Drugs and Neuroplasticity
Pharmaceuticals, 2011 Drugs of abuse induce plastic changes in the brain that seem to underlie addictive phenomena. These plastic changes can be structural (morphological) or synaptic (biochemical), and most of them take place in the mesolimbic and mesostriatal circuits ...

The tyrosine kinase FER is responsible for the capacitation-associated increase in tyrosine phosphorylation in murine sperm [PDF]
, 2016 Sperm capacitation is required for fertilization. At the molecular level, this process is associated with fast activation of protein kinase A. Downstream of this event, capacitating conditions lead to an increase in tyrosine phosphorylation. The identity

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes
The Journal of Physiology, EarlyView.Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Astrocytes: Orchestrators of brain gas exchange and oxygen homeostasis
The Journal of Physiology, EarlyView.Abstract figure legend Oxygen and carbon dioxide enter the body via breathing; in the brain astrocytes play a key role balancing oxygen delivery with carbon dioxide removal. Abstract If we consider neurons like muscles during exercise, the demand for oxygen (O2) and carbon dioxide (CO2) elimination is constantly changing.

Glucose is a pH-dependent motor for sperm beat frequency during early activation.
PLoS ONE, 2012 To reach the egg in the ampulla, sperm have to travel along the female genital tract, thereby being dependent on external energy sources and substances to maintain and raise the flagellar beat. The vaginal fluid is rich in lactate, whereas in the uterine

Calmodulin in Complex with Proteins and Small Molecule Ligands: Operating with the Element of Surprise. Implications for Structure-Based Drug Design [PDF]
, 2009 Calmodulin plays a role in several life processes, its flexibility allows binding of a number of different ligands from small molecules to amphiphilic peptide helices and proteins. Through the diversity of its functions, it is quite difficult to find new

The Journal of Physiology, EarlyView.Abstract figure legend Modelling β‐adrenergic stimulation in sympathetically remodelled ventricular substrates. Myocardial infarction could result in sympathetic remodelling in ventricular tissues, which affects arrhythmia dynamics. However sympathetic remodelling is challenging to control experimentally; therefore we created an ionic model that ...
