EOG8PK4Q6	GO:0005578	1/15	proteinaceous extracellular matrix	cellular_component	"A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus." [GOC:mtg_sensu, ISBN:0198547684]
EOG8PK4Q6	GO:0005886	1/15	plasma membrane	cellular_component	"The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins." [ISBN:0716731363]
EOG8PK4Q6	GO:0031225	1/15	anchored component of membrane	cellular_component	"The component of a membrane consisting of the gene products that are tethered to the membrane only by a covalently attached anchor, such as a lipid group that is embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping." [GOC:dos, GOC:mah]
