Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.",IEA GO:0007266,BP,"Rho protein signal transduction","A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.",TAS GO:0008360,BP,"regulation of cell shape","Any process that modulates the surface configuration of a cell.",IBA GO:0012505,CC,"endomembrane system","A collection of membranous structures involved in transport within the cell.
