A K+-selective CNG channel orchestrates Ca2+ signalling in zebrafish sperm

Calcium in the flagellum controls sperm navigation. In sperm of marine invertebrates and mammals, Ca2+ signalling has been intensely studied, whereas for fish little is known. In sea urchin sperm, a cyclic nucleotide-gated K+ channel (CNGK) mediates a cGMP-induced hyperpolarization that evokes Ca2+...
