Repression of transcription by conversion of large regions of DNA into an inaccessible state often called heterochromatin.

cyclin-dependent protein kinase 5 activator complex

Activates cyclin-dependent kinase 5; composed of regulatory and catalytic subunits.

cyclin-dependent protein kinase 5 activator activity

cyclin-dependent protein kinase 5 activator, intrinsic catalyst activity

cyclin-dependent protein kinase regulator activity

Modulates the activity of a cyclin-dependent protein kinase, enzymes of the protein kinase family that are regulated through association with cyclins and other proteins.

The removal of an internal amino acid sequence (an intein) from a protein during protein maturation; the excision of inteins is precise and the N- and C-terminal exteins are joined by a normal peptide bond. Protein splicing involves 4 nucleophilic displacements by the 3 conserved splice junction residues.

Heritable alterations in the activity of a gene that depend on whether it passed through the paternal or the maternal germline, but that are not encoded by DNA itself.

Enables the directed movement of organic cations into, out of, within or between cells. Organic cations are atoms or small molecules with a positive charge which contain carbon in covalent linkage.

Enables the directed movement of inorganic anions into, out of, within or between cells. Inorganic anions are atoms or small molecules with a negative charge which do not contain carbon in covalent linkage.

Enables the directed movement of arsenite into, out of, within or between cells.

Enables the directed movement of bicarbonate into, out of, within or between cells. Bicarbonate is the hydrogencarbonate ion, HCO3-.

Enables the directed movement of chloride ions into, out of, within or between cells.

The covalent or conformational alteration of one or more nucleotides within RNA, resulting in a change in the properties of the RNA.

The sequence of enzymatic reactions by which the 5' cap structure, an inverted 7-methylguanosine linked via a 5'-5' triphosphate bridge (m7G(5')ppp(5')X) to the first transcribed residue, is added to a nascent RNA polymerase II transcript.
