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.

Involved in catalyzing the release of a nascent polypeptide chain from a ribosome.

The directed movement of L-glutamine, 2-amino-4-carbamoylbutanoic acid, into, out of, within or between cells.

Cell death resulting from activation of endogenous cellular processes.

The directed movement of lipids into, out of, within or between cells. Lipids are compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.

Catalysis of the reaction: ATP(out) + ADP(in) = ATP(in) + ADP(out).

A process which directly activates any of the steps required for programmed cell death.

A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.

The membrane surrounding any vesicle in the cell.

The ordered and organized complex of DNA and protein that forms the chromosome in the nucleus.

Enables the directed movement of substances within a cell.

Interacting selectively with the 3' untranslated region of an mRNA molecule.

A dispersed and relatively uncompacted form of chromatin.

The part of the cytoskeleton (the internal framework of a cell) composed of actin. Includes actin cytoskeleton-associated complexes.
