The chemical reactions involving a nucleoside, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleotide), e.g. adenosine, guanosine, inosine, cytidine, uridine and deoxyadenosine, deoxyguanosine, deoxycytidine and thymidine (= deoxythymidine).

The chemical reactions involving a nucleotide, a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates).

The selective interaction of a protein with specific molecules in the cytoplasm, thereby inhibiting its transport into other areas of the cell.

Interacting selectively with a 7-methylguanosine (m7G) moiety or derivative located at the 5' end of an RNA molecule.

The chemical reactions involving any ribonucleoside, a nucleoside in which purine or pyrimidine base is linked to a ribose (beta-D-ribofuranose) molecule.

positive regulation of protein transport

Any process that activates or increases the rate of the directed movement of a protein into, out of, within or between cells.

Any process that modulates the frequency, rate or extent of the directed movement of a protein into, out of, within or between cells.

negative regulation of protein transport

Any process that stops, prevents or reduces the rate of the directed movement of a protein into, out of, within or between cells.

The formation of the spindle, the array of microtubules and associated molecules that serves to move duplicated chromosomes apart.

The formation of the spindle during a mitotic cell cycle.

The directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

The breakdown into simpler components of pyrimidine nucleoside diphosphate, a glycosamine consisting of a pyrimidine base linked to a ribose or deoxyribose sugar esterified with diphosphate on its glycose moiety.

The directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.
