The change in form (cell shape and size) that occurs when relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history.

The process leading to the attainment of full functional capacity of an erythrocyte.

Interacting selectively with hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin.

A thin cytoplasmic bridge formed between daughter cells at the end of cytokinesis. The midbody forms where the contractile ring constricts, and may persist for some time before finally breaking to complete cytokinesis.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

Interacting selectively with an aryl hydrocarbon receptor.

Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes.

negative regulator of basal transcription activity

The volume enclosed by the membranes of a particular organelle, e.g. endoplasmic reticulum lumen, or the space between the two lipid bilayers of a double membrane surrounding an organelle, e.g. nuclear membrane lumen.

Any protein group composed of two or more subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleic acids, metal ions or carbohydrate groups.

Any protein group composed of two or more subunits, which may or may not be identical, which undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

Interacting selectively with laminins, glycoproteins that are major constituents of the basement membrane of cells.
