| Identifier | Name | Description |
|---|---|---|
| GO:0043234 | protein complex | A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical. |
| GO:0032991 | macromolecular complex | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which the constituent parts function together. |
| GO:0005575 | cellular_component | The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| GO:0036454 | growth factor complex | A protein complex that has growth factor activity. |
| GO:1990265 | platelet-derived growth factor complex | A protein complex consisting of two chains of platelet-derived growth factor (PDGF) subunits. PDGF dimers bind to PDGF receptors in the plasma membrane and induce receptor dimerisation and activation. PDGFs are involved in a wide variety of signalling processes. PDGFs are found in all vertebrates where at least 2 different chains (A and B) exist. In human (and other mammals), four types of PDGF chains (A, B, C, and D) are known which form five different dimers (AA, AB, BB, CC and DD). |
