	GO:0016557	peroxisome membrane biogenesis	The process in which a peroxisome membrane is synthesized, aggregates, and bonds together.
	GO:0007031	peroxisome organization	A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a peroxisome. A peroxisome is a small, membrane-bounded organelle that uses dioxygen (O2) to oxidize organic molecules.
	GO:0002230	positive regulation of defense response to virus by host	Any host process that results in the promotion of antiviral immune response mechanisms, thereby limiting viral replication.
	GO:0098779	positive regulation of macromitophagy in response to mitochondrial depolarization	The macromitophagy process that is triggered by a detection of the loss of mitochondrial membrane potential.
	GO:0045046	protein import into peroxisome membrane	The targeting of proteins into the peroxisomal membrane. The process is not well understood, but both signals and mechanism differ from those involved in peroxisomal matrix protein import.
	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:0098792	xenophagy	The macroautophagy process in which a region of cytoplasm containing an intracellular pathogen or some part of an intracellular pathogen (e.g. viral capsid) is enclosed in a double membrane bound autophagosome, which then fuses with the lysosome leading to degradation of the contents.
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
	GO:0005783	endoplasmic reticulum	The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
	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:0005779	integral component of peroxisomal membrane	The component of the peroxisomal 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:0043231	intracellular membrane-bounded organelle	Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005654	nucleoplasm	That part of the nuclear content other than the chromosomes or the nucleolus.
	GO:0005778	peroxisomal membrane	The lipid bilayer surrounding a peroxisome.
	GO:0005777	peroxisome	A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism.
	GO:0043234	protein complex	A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
	GO:0032994	protein-lipid complex	A macromolecular complex containing separate protein and lipid molecules. Separate in this context means not covalently bound to each other.

Chain B (PEX19_HUMAN | P40855)

molecular function
	GO:0051117	ATPase binding	Interacting selectively and non-covalently with an ATPase, any enzyme that catalyzes the hydrolysis of ATP.
	GO:0036105	peroxisome membrane class-1 targeting sequence binding	Interacting selectively and non-covalently with a class I peroxisomal membrane targeting sequence, any of several sequences of amino acids within a protein that can act as a signal for the localization of the protein into the peroxisome membrane in a PEX19-dependent manner.
	GO:0047485	protein N-terminus binding	Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
	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).
biological process
	GO:0061077	chaperone-mediated protein folding	The process of inhibiting aggregation and assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure that is dependent on interaction with a chaperone.
	GO:0072321	chaperone-mediated protein transport	The directed movement of proteins into, out of or within a cell, or between cells, mediated by chaperone molecules that bind to the transported proteins.
	GO:0072663	establishment of protein localization to peroxisome	The directed movement of a protein to a specific location in a peroxisome.
	GO:1900131	negative regulation of lipid binding	Any process that stops, prevents or reduces the frequency, rate or extent of lipid binding.
	GO:0016559	peroxisome fission	The division of a mature peroxisome within a cell to form two or more separate peroxisome compartments.
	GO:0016557	peroxisome membrane biogenesis	The process in which a peroxisome membrane is synthesized, aggregates, and bonds together.
	GO:0007031	peroxisome organization	A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a peroxisome. A peroxisome is a small, membrane-bounded organelle that uses dioxygen (O2) to oxidize organic molecules.
	GO:0045046	protein import into peroxisome membrane	The targeting of proteins into the peroxisomal membrane. The process is not well understood, but both signals and mechanism differ from those involved in peroxisomal matrix protein import.
	GO:0050821	protein stabilization	Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.
	GO:0006625	protein targeting to peroxisome	The process of directing proteins towards the peroxisome, usually using signals contained within the protein.
	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
cellular component
	GO:0031526	brush border membrane	The portion of the plasma membrane surrounding the brush border.
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
