Descriptions

Protein kinase C is a multi-module Ser/Thr protein kinase that transduces the abundance of signals resulting in phospholipid hydrolysis. Binding of diacylglycerol allosterically and reversibly activates these enzymes to affect their major role in maintaining cellular homeostasis. This allosteric regulation is precisely controlled by multiple mechanisms that ensure that the enzyme is only active for specific times at specific locations in response to specific signals. <br> PKC consists of a regulatory moiety (pseudosubstrate site, C1A and C1B able to bind phorbol esters and diacylglycerol, and calcium-binding C2 domain) and protein kinase domain. The kinase domain is followed by a C-Tail that is a hallmark regulatory region of AGC kinases and serves as a docking site for regulatory proteins. <br>The pseudosubstrate binds the substrate-binding cavity of the kinase domain and operates as an autoinhibitory segment. While the pseudosubstrate-C1A is the dominant autoinhibitory module and is necessary for the autoinhibition of all PKC family members, all domains in the regulatory module participate in a network of interactions to maintain autoinhibition. <br>

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
inaD signaling complex 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.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
rhabdomere 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.

5 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
diacylglycerol-dependent serine/threonine kinase activity Catalysis of the reaction
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions
zinc ion binding Binding to a zinc ion (Zn).

14 GO annotations of biological process

Name Definition
adaptation of rhodopsin mediated signaling The process in which a rhodopsin-mediated signaling pathway is adjusted to modulate the sensitivity and response of a visual system to light stimuli (that might vary over more than 6 magnitudes in intensity) without response saturation.
calcium-mediated signaling Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions.
cell migration The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues.
deactivation of rhodopsin mediated signaling The process of restoring the photoreceptor cell to its unexcited state after termination of the stimulus (photon).
detection of light stimulus involved in sensory perception The series of events in which a light stimulus is received by a cell and converted into a molecular signal as part of the sensory perception of light.
female gonad development The process whose specific outcome is the progression of the female gonad over time, from its formation to the mature structure.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
phospholipase C-inhibiting G protein-coupled receptor signaling pathway A G protein-coupled receptor signaling pathway which proceeds with inhibition of phospholipase C (PLC) activity and a subsequent decrease in the levels of cellular inositol trisphosphate (IP3) and diacylglycerol (DAG).
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
phototransduction The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.
positive regulation of clathrin-dependent endocytosis Any process that activates or increases the frequency, rate or extent of clathrin-mediated endocytosis.
response to ethanol 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 an ethanol stimulus.
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.
visual perception The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image.
