| 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:0030021 | extracellular matrix structural constituent conferring compression resistance | molecular_function | A constituent of the extracellular matrix that enables the matrix to resist compressive forces; often a proteoglycan. [GOC:mah, ISBN:0815316194] |
| GO:0007181 | transforming growth factor beta receptor complex assembly | biological_process | The aggregation, arrangement and bonding together of a ligand-bound type II transforming growth factor beta (TGF-beta) receptor dimer with a type I TGF-beta receptor dimer, following ligand binding, to form a heterotetrameric TGF-beta receptor complex. [GOC:jl, Reactome:R-HSA-170840, Wikipedia:TGF_beta_signaling_pathway] |
| GO:0030199 | collagen fibril organization | biological_process | Any process that determines the size and arrangement of collagen fibrils within an extracellular matrix. [GOC:mah, ISBN:0815316194] |
| 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: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] |
| GO:0005796 | Golgi lumen | cellular_component | The volume enclosed by the membranes of any cisterna or subcompartment of the Golgi apparatus, including the cis- and trans-Golgi networks. [GOC:mah] |
| GO:0031012 | extracellular matrix | cellular_component | A structure lying external to one or more cells, which provides structural support, biochemical or biomechanical cues for cells or tissues. [GOC:BHF, GOC:mah, GOC:rph, NIF_Subcellular:nlx_subcell_20090513, PMID:21123617, PMID:28089324] |
| GO:0043202 | lysosomal lumen | cellular_component | The volume enclosed within the lysosomal membrane. [GOC:jl, PMID:15213228] |
