PLCζ causes Ca2+ oscillations in mouse eggs by targeting intracellular and not plasma membrane PI(4,5)P2

Sperm-specific phospholipase C ζ (PLCζ) activates embryo development by triggering intracellular Ca(2+) oscillations in mammalian eggs indistinguishable from those at fertilization. Somatic PLC isozymes generate inositol 1,4,5-trisphophate-mediated Ca(2+) release by hydrolyzing phosphatidylinositol 4,5-bisphosphate (PI(4,5)P(2)) in the plasma membrane. Here we examine the subcellular source of ...

Selective interaction of the C2 domains of phospholipase C-b1 and -b2 with activated Gaq subunits: An alternative function for C2-signaling modules

Phospholipase C (PLC)-b1 and PLC-b2 are regulated by the Gq family of heterotrimeric G proteins and contain C2 domains. These domains are Ca21-binding modules that serve as membrane-attachment motifs in a number of signal transduction proteins. To determine the role that C2 domains play in PLC-b1 and PLC-b2 function, we measured the binding of the isolated C2 domains to membrane bilayers. We fo...

Phosphatidylinositol 4-OH kinase is a downstream target of neuronal calcium sensor-1 in enhancing exocytosis in neuroendocrine cells.

Neuronal calcium sensor-1 (NCS-1), the mammalian orthologue of frequenin, belongs to a family of EF-hand-containing Ca(2+) sensors. NCS-1/frequenin has been shown to enhance synaptic transmission in PC12 cells and Drosophila and Xenopus, respectively. However, the precise molecular mechanism for the enhancement of exocytosis is largely unknown. In PC12 cells, NCS-1 potentiated exocytosis evoked...

Efficient pig ICSI using Percoll-selected spermatozoa; evidence for the essential role of phospholipase C-ζ in ICSI success

In pigs, the damaged sperm membrane leads to leakage of phospholipase C-ζ (PLCζ), which has been identified as a sperm factor, and a reduction of oocyte-activating ability. In this study, we investigated whether sperm selected by Percoll gradient centrifugation (Percoll) have sufficient PLCζ, and whether the efficiency of fertilization and blastocyst formation after intracytoplasmic sperm injec...

Isolation of cDNAs encoding typical and novel types of phosphoinositide-specific phospholipase C from the moss Physcomitrella patens.

Two cDNAs encoding proteins, PpPLC1 and PpPLC2, with catalytic and C2 domains conserved in plant phosphoinositide-specific phospholipase C (PI-PLC) were isolated from Physcomitrella patens. The N domain, which has been identified in Arabidopsis PI-PLCs as an EF hand-like domain, was found in both isoforms, although that in PpPLC2 was a split type. At micromolar Ca2+ concentrations, PpPLC1 prefe...
