The assembly of chromatin into heterochromatin, a compact and highly condensed form that is often, but not always, transcriptionally silent.

The chemical reactions involving cyclic AMP, adenosine 3',5'-phosphate.

The directed movement of oxygen (O2) into, out of, within or between cells.

The directed movement of inorganic cations with a valency of one into, out of, within or between cells. Inorganic cations are atoms or small molecules with a positive charge which do not contain carbon in covalent linkage.

di-, tri-valent inorganic cation transport

The directed movement of inorganic cations with a valency of two or three into, out of, within or between cells. Inorganic cations are atoms or small molecules with a positive charge which do not contain carbon in covalent linkage.

Acting as a marker to identify a membrane and interacting selectively with one or more SNAREs on another membrane to mediate membrane fusion.

Enables the directed movement of substances between the nucleus and the cytoplasm of a cell.

The chemical reactions involving dUTP, deoxyuridine (5'-)triphosphate.

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

The chemical reactions involving adenine, 6-aminopurine, one of the five main bases found in nucleic acids and a component of numerous important derivatives of its corresponding ribonucleoside, adenosine.

The directed movement of purines, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, into, out of, within or between cells.

Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide.

The directed movement of amino acids, organic acids containing one or more amino substituents, into, out of, within or between cells.

Functions in chain elongation during polypeptide synthesis at the ribosome.

The chemical reactions involving cytidine, cytosine riboside, a widely distributed nucleoside.

The directed movement of L-asparagine, the levorotatory isomer of alpha-aminosuccinamic acid, into, out of, within or between cells.
