Role of tyrosine phosphorylation in sperm capacitation / acrosome reaction

open access: yes, 2004
Capacitation is an important physiological pre-requisite before the sperm cell can acrosome react and fertilize the oocyte. Recent reports from several laboratories have amply documented that the protein phosphorylation especially at tyrosine residues is

Sperm Ecto-Protein Kinase and Its Protein Substrate: Novel Regulators of Membrane Fusion During Acrosome Reaction

open access: yes, 2009
Previously we have purified and characterized a unique plasma membrane-specific cyclic AMP-independent ecto-protein kinase (ecto-CIK) as well as its ecto-phosphoprotein substrate (MPS) using caprine sperm model. This study reports for the first time the

Effects of the purified IGF-I complex on the capacitation and acrosome reaction of rabbit spermatozoa

open access: yes, 2001
A protein complex containing IGF-I, purified from rabbit seminal plasma, was used to investigate its effects on the capacitation and acrosome reaction of rabbit spermatozoa.

The relationship between acrosome reaction and polyunsaturated fatty acid composition in boar sperm

open access: yes, 2020
This study investigated the relationship between acrosome reactions and fatty acid composition with respect to fertility in boar sperm. The acrosome reaction was induced more than 85% by 60 mM methyl‐beta‐cyclodextrin (MBCD), and plasma membrane ...

Protease activity involvement in the passage of mammalian sperm through the zona pellucida

open access: yesBiological Research, 2011
The interaction between acrosome-reacted sperm and zona pellucida proteins is not yet fully understood. Serine protease acrosin and its zymogen proacrosin have been proposed to fulfill this function due to their capacity to bind zona pellucida ...

Sperm acrosome associated 3 protein expression and antigenicity in horses

open access: yes
Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans ...

Calcium ionophore A23187 versus progesterone: induction of acrosome reaction in thawed and prepared cryopreserved semen samples

open access: yes
Background: Acrosome reaction facilitates fertilization and it can be induced in-vitro using various stimuli like progesterone, calcium ionophore A23187, prostaglandins, etc.
