Chain A (GNAT1_BOVIN | P04695)

molecular function
	GO:0031683	G-protein beta/gamma-subunit complex binding	Interacting selectively and non-covalently with a complex of G-protein beta/gamma subunits.
	GO:0001664	G-protein coupled receptor binding	Interacting selectively and non-covalently with a G-protein coupled receptor.
	GO:0019003	GDP binding	Interacting selectively and non-covalently with GDP, guanosine 5'-diphosphate.
	GO:0005525	GTP binding	Interacting selectively and non-covalently with GTP, guanosine triphosphate.
	GO:0003924	GTPase activity	Catalysis of the reaction: GTP + H2O = GDP + phosphate.
	GO:0000035	acyl binding	Interacting selectively and non-covalently with an acyl group, any group formally derived by removal of the hydroxyl group from the acid function of a carboxylic acid.
	GO:0019001	guanyl nucleotide binding	Interacting selectively and non-covalently with guanyl nucleotides, any compound consisting of guanosine esterified with (ortho)phosphate.
	GO:0000166	nucleotide binding	Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
	GO:0005515	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).
	GO:0019901	protein kinase binding	Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.
	GO:0004871	signal transducer activity	Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
biological process
	GO:0007186	G-protein coupled receptor signaling pathway	A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
	GO:0007188	adenylate cyclase-modulating G-protein coupled receptor signaling pathway	The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand, where the pathway proceeds through activation or inhibition of adenylyl cyclase activity and a subsequent change in the concentration of cyclic AMP (cAMP).
	GO:0008283	cell proliferation	The multiplication or reproduction of cells, resulting in the expansion of a cell population.
	GO:0071257	cellular response to electrical stimulus	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electrical stimulus.
	GO:0050908	detection of light stimulus involved in visual perception	The series of events involved in visual perception in which a light stimulus is received and converted into a molecular signal.
	GO:0042462	eye photoreceptor cell development	Development of a photoreceptor, a sensory cell in the eye that reacts to the presence of light. They usually contain a pigment that undergoes a chemical change when light is absorbed, thus stimulating a nerve.
	GO:0051344	negative regulation of cyclic-nucleotide phosphodiesterase activity	Any process that stops or reduces the rate of cyclic nucleotide phosphodiesterase activity, the catalysis of the reaction: nucleotide 3',5'-cyclic phosphate + H2O = nucleotide 5'-phosphate.
	GO:0007602	phototransduction	The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.
	GO:0007603	phototransduction, visible light	The sequence of reactions within a cell required to convert absorbed photons from visible light into a molecular signal. A visible light stimulus is electromagnetic radiation that can be perceived visually by an organism; for organisms lacking a visual system, this can be defined as light with a wavelength within the range 380 to 780 nm.
	GO:0022400	regulation of rhodopsin mediated signaling pathway	Any process that modulates the frequency, rate or extent of rhodopsin-mediated signaling.
	GO:0009416	response to light stimulus	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 light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.
	GO:0050896	response to stimulus	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 stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
	GO:0060041	retina development in camera-type eye	The process whose specific outcome is the progression of the retina over time, from its formation to the mature structure. The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates.
	GO:0016056	rhodopsin mediated signaling pathway	The series of molecular signals generated as a consequence of excitation of rhodopsin by a photon and the events that convert the absorbed photons into a cellular response.
	GO:0050917	sensory perception of umami taste	The series of events required to receive an umami taste stimulus, convert it to a molecular signal, and recognize and characterize the signal.

	GO:0007165	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.
