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.

Catalysis of the reaction: glucose(out) + Na+(out) = glucose(in) + Na+(in).

regulation of response to osmotic stress

Any process that modulates the rate or extent of the response to osmotic stress.

Catalysis of the stereospecific transfer of a substrate across a biological membrane.

Catalysis of the reaction: amino acid(out) + cation(out) = amino acid(in) + cation(in).

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

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

The series of events by which a biotic (living) stimulus is received and converted into a molecular signal.

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

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

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules.

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

Interacting selectively with monomeric or multimeric forms of tubulin, including microtubules.
