Immature acetylcholine receptors
WitrynaIn human sperm, there also appears to be a role for a nicotinic acetylcholine receptor (nAChRs). One of the actions of ZP3 is to stimulate glycine receptors (GlyRs), and this causes a small depolarization that contributes to the early signal transduction step during the acrosome reaction. Witryna22 sie 2024 · Cholinergic receptors function in signal transduction of the somatic and autonomic nervous systems. The receptors are named because they become activated by the ligand acetylcholine. These receptors subdivide into nicotinic and muscarinic receptors, which are named secondary to separate activating ligands that contributed …
