Chain A (ACTP1_STIHL | P81662)

molecular function
	GO:0015267	channel activity	Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules.
biological process
	GO:0006812	cation transport	The directed movement of cations, atoms or small molecules with a net positive charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0019835	cytolysis	The rupture of cell membranes and the loss of cytoplasm.
	GO:0044179	hemolysis in other organism	The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another.
	GO:0052331	hemolysis in other organism involved in symbiotic interaction	The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another, where two organisms are in a symbiotic interaction.
	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:0046931	pore complex assembly	The aggregation, arrangement and bonding together of a set of components to form a pore complex. A pore complex is a small opening in a membrane that allows the passage of liquids and/or gases.
	GO:0055085	transmembrane transport	The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
	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:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
	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:0042151	nematocyst	An organelle found in cnidoblast (nematoblast) cells. When matured, these stinging organelles store toxins and can deliver them when the cnidocil (a short extension of the cnidocyst) is stimulated by a prey or another stimulus.
	GO:0044218	other organism cell membrane	The cell membrane of a secondary organism with which the first organism is interacting.
	GO:0044279	other organism membrane	A membrane of a secondary organism with which the first organism is interacting.
	GO:0046930	pore complex	Any small opening in a membrane that allows the passage of gases and/or liquids.
