| GO term | GO name | GO namespace | GO def |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0030020 | extracellular matrix structural constituent conferring tensile strength | molecular_function | A constituent of the extracellular matrix that enables the matrix to resist longitudinal stress. [GOC:mah, ISBN:0815316194] |
| GO:0042803 | protein homodimerization activity | molecular_function | Binding to an identical protein to form a homodimer. [GOC:jl] |
| GO:0001501 | skeletal system development | biological_process | The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton). [GOC:dph, GOC:jid, GOC:tb] |
| GO:0005576 | extracellular region | cellular_component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| GO:0005788 | endoplasmic reticulum lumen | cellular_component | The volume enclosed by the membranes of the endoplasmic reticulum. [ISBN:0198547684] |
| GO:0062023 | collagen-containing extracellular matrix | cellular_component | An extracellular matrix consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that provides not only essential physical scaffolding for the cellular constituents but can also initiate crucial biochemical and biomechanical cues required for tissue morphogenesis, differentiation and homeostasis. The components are secreted by cells in the vicinity and form a sheet underlying or overlying cells such as endothelial and epithelial cells. [GOC:BHF, GOC:rph, PMID:21123617] |
| GO:0005594 | collagen type IX trimer | cellular_component | A collagen heterotrimer containing type IX alpha chains in alpha1(IX)alpha2(IX)alpha3(IX) trimers; type IX collagen triple helices associate to form a structure that links glycosaminoglycans to type II collagen fibrils. [ISBN:0721639976] |
| GO:0030198 | extracellular matrix organization | biological_process | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix. [GOC:mah] |
| GO:0005615 | extracellular space | cellular_component | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. [ISBN:0198547684] |
