binding of sperm to zona pellucida

Definition

Target type: biologicalprocess

The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

erastinerastin : A member of the class of quinazolines that is quinazolin-4(3H)-one in which the hydrogens at positions 2 and 3 are replaced by 1-{4-[(4-chlorophenoxy)acetyl]piperazin-1-yl}ethyl and 2-ethoxyphenyl groups, respectively. It is an inhibitor of voltage-dependent anion-selective channels (VDAC2 and VDAC3) and a potent ferroptosis inducer.
