Down-regulation of CatSper 1 and CatSper 2 genes by lead and mercury [PDF]

open access: yesEnvironmental Toxicology and Pharmacology, 2018
In the study of the expression of CatSper genes, consideration of the effects of environmental metal toxicity is very important. Therefore, in this study, the effects of lead acetate and mercury chloride exposure on expression of CatSper genes, sperm ...

The CatSper channel modulates boar sperm motility during capacitation

open access: yesReproductive Biology, 2017
The cation channel of sperm (CatSper) comprises four transmembrane subunits specifically expressed in human, equine, murine and ovine spermatozoa, apparently implicated in capacitation, hyperactivation and acrosome exocytosis.

CatSper Calcium Channels: 20 Years On

Physiology, 2023
The flagellar-specific Ca2+channel CatSper is the predominant Ca2+entry site in mammalian sperm. CatSper-mediated Ca2+signaling affects nearly every event that regulates sperm to acquire fertilizing capability. In this review, we summarize some of the main findings from 20 years of CatSper research and highlight recent progress and prospects.

A CUG-initiated CATSPERθ functions in the CatSper channel assembly and serves as a checkpoint for flagellar trafficking [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2023
Calcium signaling is critical for successful fertilization. In spermatozoa, calcium influx into the sperm flagella mediated by the sperm-specific CatSper calcium channel is necessary for hyperactivated motility and male fertility.

Regulation of the sperm calcium channel CatSper by endogenous steroids and plant triterpenoids [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance The calcium channel of sperm—CatSper—is vital for male fertility. CatSper is activated by the hormone progesterone, but its pharmacological profile is not well studied.
