The invasion by an organism of a cell of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.

Catalysis of the identification and base-pairing of homologous sequences between single-stranded DNA and double-stranded DNA.

The morphological and physiological alterations undergone by the nucleus during apoptosis.

A protein complex that includes a ubiquitin-protein ligase (E3) and other proteins that may confer substrate specificity on the complex.

The compaction of chromatin during apoptosis.

Catalysis of the reaction: (S)-3-(5-oxo-4,5-dihydro-3H-imidazol-4-yl)propanoate + H2O = H+ + N-formimidoyl-L-glutamate.

A ubiquitin ligase complex found in the nucleus.

The breakdown of the nucleus into small membrane-bounded compartments, or blebs, each of which contain compacted DNA.

A ubiquitin ligase complex found in the cytoplasm.

The regulated release of arachidonic acid from a cell or group of cells.

The enzymatic modification of the chemical structure of specific sites in rRNA.

Catalysis of the reaction: 5'-IMP + H2O = inosine + phosphate.

Catalysis of the phosphorylation of a specific transcription regulator in response to the presence of a particular signal substance outside the cell.

Catalysis of the reaction: glycolate + NADP+ = glyoxylate + NADPH + H+.

Alters the level of transcription of target genes, usually by binding to a transcription factor, when phosphorylated by a sensor that detects the presence of a particular signal substance outside the cell.

protein phosphatase type 2A, intrinsic catalyst activity

Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. A protein serine/threonine phosphatase that is polycation-stimulated (PCS), being directly stimulated by protamine, polylysine, or histone H1; it constitutes a subclass of several enzymes activated by different histones and polylysine.
