A multisubunit protein complex that plays a central role in chromosome condensation.

The core heterodimer of a condensin complex, a multisubunit protein complex that plays a central role in chromosome condensation.

The directed movement of oligopeptides into, out of, within or between cells. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

The transport of substances that occurs outside cells.

The process of binding or confining iron ions in an intracellular area such that they are separated from other components of a biological system.

The regulation of the levels, transport, and metabolism of sodium ions within a cell or between a cell and its external environment.

Any process that modulates the volume of a cell.

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

The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.

The release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This is the process whereby most molecules are secreted from eukaryotic cells.

endoplasmic reticulum to Golgi transport

The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.

Interacting selectively with a toxin, a poisonous substance that causes damage to biological systems. Toxins are differentiated from simple chemical poisons and vegetable alkaloids by their high molecular weight and antigenicity (they elicit an antibody response).

Interacting selectively with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
