Network model predicts that CatSper is the main Ca2+ channel in the regulation of sea urchin sperm motility

Scientific Reports, 2017
Spermatozoa sea urchin swimming behaviour is regulated by small peptides from the egg outer envelope. Speract, such a peptide, after binding to its receptor in Strongylocentrotus purpuratus sperm flagella, triggers a signaling pathway that culminates ...

Inhibition of the CatSper Channel and NOX5 Enzyme Activity Affects the Functions of the Progesterone-Stimulated Human Sperm

Iranian Journal of Medical Sciences, 2018
Background: Low levels of reactive oxygen species (ROS) and calcium are necessary for sperm function. NADPH oxidase 5 (NOX5) is a membrane enzyme which produces ROS. This enzyme is dependent on calcium for its activity.

Canal catiónico específico del espermatozoide: CatSper

TIP Revista Especializada en Ciencias Químico-Biológicas
El canal catiónico específico del espermatozoide (CatSper) es un canal conductor de calcio esencial para regular la movilidad hiperactivada y, en última instancia, la promoción de la fertilidad en los espermatozoides. Este canal se localiza en el flagelo del espermatozoide y está regulado por la alcalinización, el voltaje y diferentes moléculas ...

Alteration in CatSper1 and 2 genes expression, sperm parameters and testis histology in varicocelized rats

International Journal of Reproductive BioMedicine, 2018
Background: CatSper gene, a member of cation channel sperm family, has an essential role in sperm motility and male fertility. Following varicocele, sperm parameters especially sperm movement decreases.
