[GOC:dos, GOC:go_curators] EOG8GMX9R GO:0005886 14/64 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."

[GOC:dos, GOC:mah, ISBN:0815316194] EOG8GMX9R GO:0007166 1/64 cell surface receptor signaling pathway biological_process "A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription."
