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

Environmental 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 parameters, histology of testis and prooxidant antioxidant balance (PAB) values of serum were ...

The CatSper channel modulates boar sperm motility during capacitation

Reproductive 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. Western blotting and immunocytochemistry showed hereby that CatSper subunits are also present in boar spermatozoa, primarily ...

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]

Proceedings 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.

CatSper channel, sperm function and male fertility [PDF]

Reproductive BioMedicine Online, 2015
A number of physiological events, such as sperm hyperactivation, chemotaxis towards the egg, capacitation and acrosome reaction, are triggered by activation of sperm ion channels in response to a diverse range of chemical cues. Cation channel of sperm (CatSper), a sperm-specific ion channel, is unique in orchestrating the events for fertilization, and ...

CatSper channels in sea urchin sperm

Cell Calcium, 2021
Sea urchin sperm swimming is regulated by speract, a decapeptide released from egg jelly that induces chemotaxis and triggers membrane potential (Em) changes, intracellular increases in cyclic nucleotides (cGMP, cAMP), pH (pHi) and calcium concentration ([Ca2+]i).
