ATP-binding cassette (ABC) transporter complex

A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In bacteria and archaebacteria, ABC transporters also recruit substrate binding proteins to bind substrate external to the cell and deliver it to the transporter.

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

The transfer of virions in order to create new infection.

The internalization of bacteria, immune complexes, and other particulate matter by phagocytosis including the membrane and cytoskeletal processes required, which involves one of three mechanisms: zippering of pseudopods around a target via repeated receptor-ligand interactions, sinking of the target directly into plasma membrane of the phagocyte, or induced uptake via an enhanced membrane ruffling of the phagocyte similar to macropinocytosis.

Interacting selectively with any glycan (polysaccharide) containing a substantial proportion of aminomonosaccharide residues.

positive regulation of gene-specific transcription

Any process that activates or increases the rate of the DNA-dependent transcription of a specific gene or genes.

The directed movement of molecules between the nucleus and the cytoplasm.

The process by which cells digest parts of their own cytoplasm; allows for both recycling of macromolecular constituents under conditions of nutrient limitation and remodeling the intracellular structure for cell differentiation.

The breakdown into simpler components of one of a family of organic molecules consisting of a pyrimidine base covalently bonded to a sugar ribose (a ribonucleoside) or deoxyribose (a deoxyribonucleoside).
