The lens is a transparent structure in the eye through which light is focused onto the retina. An example of this process is found in Mus musculus.",IEA GO:0005085,MF,"guanyl-nucleotide exchange factor activity","Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.",IEA GO:0005515,MF,"protein binding","Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).",IPI GO:0005622,CC,intracellular,"The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.",IEA GO:0007165,BP,"signal transduction","The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. 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:0007264,BP,"small GTPase mediated signal transduction","Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.",IEA GO:0033138,BP,"positive regulation of peptidyl-serine phosphorylation","Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-serine.",IMP GO:0042493,BP,"response to drug","Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus.
