The maintenance of the integrity of extrachromosomal plasmid DNA; includes processes that ensure plasmids are retained in the daughter cells after cell division.

A complex of the endoplasmic reticulum that catalyzes S-palmitoylation, the addition of palmitate (C16:0) or other long-chain fatty acids to proteins at a cysteine residue.

A protein complex with palmitoyltransferase activity.

The process in which the number of copies of a gene is increased in certain cells as extra copies of DNA are made in response to certain signals of cell development or of stress from the environment.

A DNA biosynthetic process that uses RNA as a template for RNA-dependent DNA polymerases (e.g. reverse transcriptase) that synthesize the new strand.

The replication of DNA that precedes meiotic cell division.

The DNA-dependent DNA replication that occurs in the nucleus of eukaryotic organisms as part of the cell cycle.

An ISWI complex that contains an ATPase subunit of the ISWI family (SNF2H in mammals) and an RSF1 homolog. It mediates nucleosome deposition and generates regularly spaced nucleosome arrays. In mammals, RSF is involved in regulation of transcription from RNA polymerase II promoters).

Any nuclear protein complex that contains an ATPase subunit of the imitation switch (ISWI) family. ISWI ATPases are involved in assembling chromatin and in sliding and spacing nucleosomes to regulate transcription of nuclear RNA polymerases I, II, and III and also DNA replication, recombination and repair.

Any process that stops, prevents, or reduces the frequency, rate or extent of a process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

Any process that modulates the frequency, rate or extent of the process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

Any process that stops, prevents or reduces the frequency, rate or extent of intracellular mRNA localization.

Any process that activates or increases the frequency, rate or extent of the process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

Any process that activates or increases the frequency, rate or extent of intracellular mRNA localization.

OBSOLETE. Any heritable epigenetic process that stops, prevents, or reduces the frequency, rate or extent of protein function by self-perpetuating conformational conversions of normal proteins in healthy cells. This is distinct from, though mechanistically analogous to, disease states associated with prion propagation and amyloidogenesis. A single protein, if it carries a glutamine/asparagine-rich ('prion') domain, can sometimes stably exist in at least two distinct physical states, each associated with a different phenotype; propagation of one of these traits is achieved by a self-perpetuating change in the protein from one form to the other, mediated by conformational changes in the glutamine/asparagine-rich domain. Prion domains are both modular and transferable to other proteins, on which they can confer a heritable epigenetic alteration of function; existing bioinformatics data indicate that they are rare in non-eukarya, but common in eukarya.

Any process that modulates the frequency, rate or extent of kinase activity, the catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.

Any process that activates or increases the frequency, rate or extent of nurse cell apoptotic process.

Any process that reduces the internal pH of an organism, part of an organism or a cell, measured by the concentration of the hydrogen ion.
