Ionic selectivity and thermal adaptations within the voltage-gated sodium channel family of alkaliphilic Bacillus [PDF]

open access: yes, 2014
Entry and extrusion of cations are essential processes in living cells. In alkaliphilic prokaryotes, high external pH activates voltage-gated sodium channels (Nav), which allows Na+ to enter and be used as substrate for cation/proton antiporters ...

The Fungal Sexual Pheromone Sirenin Activates the Human CatSper Channel Complex

open access: yesACS Chemical Biology, 2015
The basal fungus Allomyces macrogynus (A. macrogynus) produces motile male gametes displaying well-studied chemotaxis toward their female counterparts. This chemotaxis is driven by sirenin, a sexual pheromone released by the female gametes. The pheromone evokes a large calcium influx in the motile gametes, which could proceed through the cation channel

Identification of human and mouse CatSper3 and CatSper4 genes: Characterisation of a common interaction domain and evidence for expression in testis

open access: yesReproductive Biology and Endocrinology, 2003
Background CatSper1 and CatSper2 are two recently identified channel-like proteins, which show sperm specific expression patterns. Through targeted mutagenesis in the mouse, CatSper1 has been shown to be required for fertility, sperm motility and for ...

Niflumic acid disrupts marine spermatozoan chemotaxis without impairing the spatiotemporal detection of chemoattractant gradients [PDF]

open access: yes, 2013
In many broadcast-spawning marine organisms, oocytes release chemicals that guide conspecific spermatozoa towards them through chemotaxis. In the sea urchin Lytechinus pictus, the chemoattractant peptide speract triggers a train of fluctuations of ...

Genomic diversity and population structure analysis reveal few genetic differences among Ethiopian indigenous sheep populations [PDF]

open access: yes, 2017
African sheep, like other domestic sheep, are domesticated from the Asiatic mouflon (Ovis orientalis). They entered the continent through the North and the Horn of Africa regions following maritime and terrestrial trading routes.
