regulation of mast cell granule exocytosis

Any process that modulates the frequency, rate, or extent of mast cell degranulation.

positive regulation of mast cell degranulation

positive regulation of mast cell granule exocytosis

Any process that activates or increases the rate, frequency or extent of mast cell degranulation.

Unwinding of the condensed nuclear chromatin of an inactive sperm nucleus.

fertilization, exchange of chromosomal proteins

Replacement of sperm-specific chromosomal proteins with somatic histones, to allow the paternal genome to acquire a nucleosomal chromatin organization compatible with nuclear activity.

Formation and organization of an aster composed of microtubule arrays originating from the sperm basal body and extending virtually to the egg periphery. The sperm aster ensures the appropriate positioning of the male and female pronuclei.

The gradual disintegration of the sperm plasma membrane following insemination. This process is seen in Drosophila after entry of the entire sperm, surrounded by its plasma membrane, into the egg.

The directed movement of the male and female pronuclei towards each other prior to their fusion.

The rotation of centrosomes and associated pronuclei in one-cell embryos such as those of Caenorhabditis elegans, occurring as a transition between pronuclear migration and pronuclear fusion.

splicing factor protein import into nucleus

The directed movement of a pre-mRNA splicing factor from the cytoplasm into the nucleus, across the nuclear membrane.

juvenile hormone acid methyltransferase activity

Catalysis of the transfer of a methyl group to juvenile hormone acid.

phosphoinositide 3-kinase complex, class IA

A complex containing a heterodimer of a catalytic Class IA phosphoinositide 3-kinase (PI3K) subunit bound to a SH2 domain-containing regulatory (adaptor) subunit. Class I PI3Ks phosphorylate phosphatidylinositol [PI], phosphatidylinositol-4-phosphate [PI(4)P] and phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2], and are divided into subclasses A and B according to the type of adaptor subunit with which they associate. Through the interaction with the SH2-containing adaptor subunits, Class IA PI3K catalytic subunits are linked to tyrosine kinase signaling pathways.
