Gene Ontology (12, 12)

Asymmetric/Biological Unit(hide GO term definitions)

Chain A (BACR_HALSA | P02945)

molecular function
	GO:0005216	ion channel activity	Enables the facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. May be either selective (it enables passage of a specific ion only) or non-selective (it enables passage of two or more ions of same charge but different size).
	GO:0009881	photoreceptor activity	The function of absorbing and responding to incidental electromagnetic radiation, particularly visible light. The response may involve a change in conformation.
biological process
	GO:0034220	ion transmembrane transport	A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
	GO:0006811	ion transport	The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0007602	phototransduction	The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.
	GO:0018298	protein-chromophore linkage	The covalent or noncovalent attachment of a chromophore to a protein.
	GO:0015992	proton transport	The directed movement of protons (hydrogen ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	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:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
