GO:0005096,MF,"GTPase activator activity","Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.",IEA
GO:0005634,CC,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.",IEA
GO:0005737,CC,cytoplasm,"All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.",IDA
GO:0009055,MF,"electron carrier activity","Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.",TAS

GO:0043535,BP,"regulation of blood vessel endothelial cell migration","Any process that modulates the frequency, rate or extent of the migration of the endothelial cells of blood vessels.",IEA
GO:0043547,BP,"positive regulation of GTPase activity","Any process that activates or increases the activity of a GTPase.",IEA
GO:0045454,BP,"cell redox homeostasis","Any process that maintains the redox environment of a cell or compartment within a cell.",IMP
GO:0055114,BP,"oxidation-reduction process","A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.",IEA
GO:0070062,CC,"extracellular exosome","A membrane-bounded vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.",IDA
