Journal ArticleDOI
Mitochondrial Participation in the Intracellular Ca2+ Network
TL;DR: It is concluded that mitochondria are active participants in cellular Ca2+ signaling, whose unique role is determined by their ability to rapidly accumulate and then release large quantities of Ca2+.
Journal ArticleDOI
CatSper1 required for evoked Ca2+ entry and control of flagellar function in sperm
Anne E. Carlson,Ruth E. Westenbroek,Timothy A. Quill,Dejian Ren,David E. Clapham,Bertil Hille,David L. Garbers,Donner F. Babcock +7 more
TL;DR: It is proposed that CatSper1 functions as a voltage-gated Ca2+ channel that controls Ca2- entry to mediate the hyperactivated motility needed late in the preparation of sperm for fertilization.
Journal ArticleDOI
Dominant role of mitochondria in clearance of large ca2+ loads from rat adrenal chromaffin cells
TL;DR: Whenever [Ca2+]c rose above approximately 500 nM, Ca2+c clearance by mitochondria exceeded clearance by either Na(+)-Ca2- exchange or the Ca2- pumps of the plasma and reticular membranes, prolonging the final return to basal levels.
Journal ArticleDOI
Sperm-specific protein kinase A catalytic subunit Cα2 orchestrates cAMP signaling for male fertility
Michael A. Nolan,Donner F. Babcock,Gunther Wennemuth,William A. Brown,Kimberly A. Burton,G. Stanley McKnight +5 more
TL;DR: Several crucial roles of PKA are defined in sperm cell biology, bringing together both known and unique PKA-mediated events that are necessary for male fertility.
Journal ArticleDOI
An adhesion-associated agonist from the zona pellucida activates G protein-promoted elevations of internal Ca2+ and pH that mediate mammalian sperm acrosomal exocytosis.
TL;DR: Results indicate that a developmentally regulated mechanism of signal transduction employs G protein(s) to couple the physiological (zona) agonist to alterations of the internal ionic mediators of acrosomal exocytosis.
