EOG8DBWXX GO:0005578 2/4 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] EOG8DBWXX GO:0031225 1/4 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] EOG8DBWXX GO:0016020 1/4 membrane cellular_component "A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it." [GOC:dos, GOC:mah, ISBN:0815316194] EOG8DBWXX GO:0005886 1/4 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]
