CC -!- FUNCTION: Member of the eIF2 complex that functions in the early steps
CC of protein synthesis by forming a ternary complex with GTP and
CC initiator tRNA (PubMed:15277680, PubMed:19131336). This complex binds
CC to a 40S ribosomal subunit, followed by mRNA binding to form a 43S pre-
CC initiation complex (PubMed:15277680, PubMed:19131336). Junction of the
CC 60S ribosomal subunit to form the 80S initiation complex is preceded by
CC hydrolysis of the GTP bound to eIF2 and release of an eIF2-GDP binary
CC complex (PubMed:15277680, PubMed:19131336). In order for eIF2 to
CC recycle and catalyze another round of initiation, the GDP bound to eIF2
CC must exchange with GTP by way of a reaction catalyzed by eIF2B
CC (PubMed:15277680, PubMed:19131336). EIF2S1/eIF2-alpha is a key
CC component of the integrated stress response (ISR), required for
CC adaptation to various stress: phosphorylation by metabolic-stress
CC sensing protein kinases (EIF2AK1/HRI, EIF2AK2/PKR, EIF2AK3/PERK and
CC EIF2AK4/GCN2) in response to stress converts EIF2S1/eIF-2-alpha in a
CC global protein synthesis inhibitor, leading to a attenuation of cap-
CC dependent translation, while concomitantly initiating the preferential
CC translation of ISR-specific mRNAs, such as the transcriptional
CC activators ATF4 and QRICH1, and hence allowing ATF4- and QRICH1-
CC mediated reprogramming (PubMed:15277680, PubMed:21285359).
CC {ECO:0000269|PubMed:15277680, ECO:0000269|PubMed:19131336,
CC ECO:0000269|PubMed:21285359}.
CC -!- ACTIVITY REGULATION: Activity is regulated by phosphorylation at Ser-49
CC and Ser-52, which stabilizes the eIF2/GDP/eIF2B complex and prevents
CC the eIF2B-mediated exchange of GDP for GTP, thereby preventing the
CC formation of the 43S pre-initiation complex (43S PIC) (PubMed:11106749,
CC PubMed:12176355, PubMed:15277680, PubMed:19131336, PubMed:21285359).
CC This results in the global attenuation of 5' cap-dependent protein
CC synthesis and concomitant translation of ISR-specific mRNAs that
CC contain a short upstream open reading frame (uORF) in their 5' UTR,
CC such as ATF4, ATF5, DDIT3/CHOP and PPP1R15A/GADD34 (PubMed:15277680,
CC PubMed:19131336, PubMed:21285359). {ECO:0000269|PubMed:11106749,
CC ECO:0000269|PubMed:12176355, ECO:0000269|PubMed:15277680,
CC ECO:0000269|PubMed:19131336, ECO:0000269|PubMed:21285359}.
CC -!- SUBUNIT: Eukaryotic translation initiation factor 2 eIF2 is a
CC heterotrimeric complex composed of an alpha (EIF2S1), a beta (EIF2S2)
CC and a gamma (EIF2S3) chain (By similarity). eIF2 is member of the 43S
CC pre-initiation complex (43S PIC). eIF2 forms a complex with at least
CC CELF1/CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5
CC (PubMed:16931514). Interaction with METAP2 protects EIF2S1 from
CC inhibitory phosphorylation (By similarity). Interacts with ABCF1 (By
CC similarity). Associates with ribosomes (By similarity). Interacts with
CC DDX3X in an RNA-independent manner (By similarity).
CC {ECO:0000250|UniProtKB:P05198, ECO:0000250|UniProtKB:P68101,
CC ECO:0000269|PubMed:16931514}.
CC -!- INTERACTION:
CC Q6ZWX6; Q9Z2R9: Eif2ak1; NbExp=6; IntAct=EBI-1202234, EBI-642878;
CC -!- SUBCELLULAR LOCATION: Cytoplasm, Stress granule
CC {ECO:0000269|PubMed:19861488}. Cytoplasm, cytosol
CC {ECO:0000250|UniProtKB:P56286}. Note=Colocalizes with NANOS3 in the
CC stress granules. {ECO:0000269|PubMed:19861488}.
CC -!- PTM: Phosphorylation at Ser-49 and Ser-52 stabilizes the eIF-
CC 2/GDP/eIF2B complex and prevents GDP/GTP exchange reaction, thus
CC impairing the recycling of eIF2 between successive rounds of initiation
CC and leading to global inhibition of translation, while concomitantly
CC initiating the preferential translation of integrated stress response
CC (ISR)-specific mRNAs (PubMed:10504407, PubMed:11106749,
CC PubMed:12176355, PubMed:15213227, PubMed:15277680, PubMed:16054071,
CC PubMed:19131336, PubMed:21285359). Substrate for at least 4 kinases:
CC EIF2AK1/HRI, EIF2AK2/PKR, EIF2AK3/PERK and EIF2AK4/GCN2
CC (PubMed:10504407, PubMed:11106749, PubMed:12176355, PubMed:15213227,
CC PubMed:15277680, PubMed:16054071). Phosphorylated; phosphorylation on
CC Ser-52 by the EIF2AK4/GCN2 protein kinase occurs in response to amino
CC acid starvation and UV irradiation (PubMed:10504407, PubMed:12176355,
CC PubMed:15213227, PubMed:16054071). {ECO:0000269|PubMed:10504407,
CC ECO:0000269|PubMed:11106749, ECO:0000269|PubMed:12176355,

CC ECO:0000269|PubMed:21285359}.
CC -!- SIMILARITY: Belongs to the eIF-2-alpha family. {ECO:0000305}.
CC -!- CAUTION: This gene should not be confused with EIF2A, with which it
CC shares the alias EIF2A. Although both of these proteins function in
CC binding initiator tRNA to the 40S ribosomal subunit, the eIF2 complex
CC requires GTP, whereas the EIF2A protein does so in a codon-dependent
CC manner. {ECO:0000305}.
