The series of events required for a bitter taste stimulus to be received and converted to a molecular signal.

An immune response taking place in mucosal tissues, including those of the intestinal tract, nasal and upper respiratory tract, and genital tract.

The chemical reactions and pathways involving phospholipids, any lipid containing phosphoric acid as a mono- or diester.

The chemical reactions and pathways resulting in the formation of diacylglycerol, a glyceride in which any two of the R groups (positions not specified) are acyl groups while the remaining R group can be either H or an alkyl group.

The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.

The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.

Locomotory behavior in a fully developed and mature organism.

The process in which the detection of light triggers the release of internally sequestered calcium ions.

The chemical reactions and pathways resulting in the formation of phospholipids, any lipid containing phosphoric acid as a mono- or diester.

The synchronization of a circadian rhythm to environmental time cues such as light.

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.

The process of restoring the photoreceptor cell to its unexcited state after termination of the stimulus (photon).

Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions.

The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.

The synchronization of a circadian rhythm to photoperiod, the intermittent cycle of light (day) and dark (night).

Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light.

The chemical reactions and pathways involving phosphatidylinositol, any glycophospholipid in which a sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.

Any process that stops, prevents, or reduces the frequency, rate or extent of programmed cell death that occurs in the compound eye retina.

Any process that increases the concentration of calcium ions in the cytosol that occurs as part of a PLC-activating G-protein coupled receptor signaling pathway. G-protein-activated PLC hydrolyses phosphatidylinositol-bisphosphate (PIP2) to release diacylglycerol (DAG) and inositol trisphosphate (IP3). IP3 then binds to calcium release channels in the endoplasmic reticulum (ER) to trigger calcium ion release into the cytosol.

Any process that activates or increases the frequency, rate or extent of clathrin-mediated endocytosis.

A complex of proteins that are involved in phototransduction and attached to the transient receptor potential (TRP) channel. The protein connections are mediated through inaD.

A complex of proteins that are involved in phototransduction and attached to the transient receptor potential (TRP) channel. The protein connections are mediated through inaD.

The specialized microvilli-containing organelle on the apical surfaces of a photoreceptor cell containing the visual pigment rhodopsin and most of the proteins involved in phototransduction.
