Chain A (ERF3_YEAST | P05453)

molecular function
	GO:0005525	GTP binding	Interacting selectively and non-covalently with GTP, guanosine triphosphate.
	GO:0003924	GTPase activity	Catalysis of the reaction: GTP + H2O = GDP + phosphate.
	GO:0000166	nucleotide binding	Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
	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).
	GO:0003747	translation release factor activity	Involved in catalyzing the release of a nascent polypeptide chain from a ribosome.
biological process
	GO:0002184	cytoplasmic translational termination	The process resulting in the release of a polypeptide chain from the ribosome in the cytoplasm, usually in response to a termination codon.
	GO:0000288	nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay	A major pathway of degradation of nuclear-transcribed mRNAs that proceeds through a series of ordered steps that includes poly(A) tail shortening and that can regulate mRNA stability.
	GO:0006412	translation	The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA or circRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA or circRNA. Translation ends with the release of a polypeptide chain from the ribosome.
	GO:0006415	translational termination	The process resulting in the release of a polypeptide chain from the ribosome, usually in response to a termination codon (UAA, UAG, or UGA in the universal genetic code).
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0010494	cytoplasmic stress granule	A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.
	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:0018444	translation release factor complex	A heterodimeric complex involved in the release of a nascent polypeptide chain from a ribosome.
