Cellular mechanisms regulating sperm-zona pellucida interaction.
For mammalian spermatozoa to exhibit the ability to bind the zona pellucida (ZP) they must undergo three distinct phases of maturation, namely, spermatogenesis (testis), epididymal maturation (epididymis) and capacitation (female reproductive tract). An impressive array of spermatozoa surface remodeling events accompany these phases of maturation and appear critical for recognition and adhesion...
متن کاملCellular mechanisms regulating non-haemostatic plasmin generation.
A variety of proteases have the potential to degrade the extracellular matrix (ECM), thereby influencing the behaviour of cells by removing physical barriers to cell migration, altering cell-ECM interactions or releasing ECM-associated growth factors. The plasminogen activation system of serine proteases is particularly implicated in this pericellular proteolysis and is involved in pathologies ...
متن کاملCellular mechanisms regulating protein synthesis and skeletal muscle hypertrophy in animals.
Growth and maintenance of skeletal muscle mass is critical for long-term health and quality of life. Skeletal muscle is a highly adaptable tissue with well-known sensitivities to environmental cues such as growth factors, cytokines, nutrients, and mechanical loading. All of these factors act at the level of the cell and signal through pathways that lead to changes in phenotype through multiple ...
متن کاملExpression of human protein phosphatase-1 in Saccharomyces cerevisiae highlights the role of phosphatase isoforms in regulating eukaryotic functions.
Human (PP1) isoforms, PP1alpha, PP1beta, PP1gamma1, and PP1gamma2, differ in primary sequences at N and C termini that potentially bind cellular regulators and define their physiological functions. The GLC7 gene encodes the PP1 catalytic subunit with >80% sequence identity to human PP1 and is essential for viability of Saccharomyces cerevisiae. In yeast, Glc7p regulates glycogen and protein syn...
متن کاملRSV hijacks cellular protein phosphatase 1 to regulate M2-1 phosphorylation and viral transcription
Respiratory syncytial virus (RSV) RNA synthesis occurs in cytoplasmic inclusion bodies (IBs) in which all the components of the viral RNA polymerase are concentrated. In this work, we show that RSV P protein recruits the essential RSV transcription factor M2-1 to IBs independently of the phosphorylation state of M2-1. We also show that M2-1 dephosphorylation is achieved by a complex formed betw...
