Eukaryotic translation initiation factor 2B subunit delta, isoform A; Translation initiation factor activity. It is involved in the biological process described with: translational initiation; Belongs to the eIF-2B alpha/beta/delta subunits family.

Eukaryotic translation initiation factor 2 subunit 2; eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This preinitiation complex mediates ribosomal recognition of a start codon during the scanning process of the leader region; Belongs to the eIF-2-beta/eIF-5 family.

Eukaryotic translation initiation factor 2B subunit alpha (eIF2Balpha) encodes a regulatory subunit of the eIF2B heteropentamer; Belongs to the eIF-2B alpha/beta/delta subunits family.

Eukaryotic translation initiation factor 2B subunit epsilon (eIF2Bepsilon) encodes a guanyl-nucleotide exchange factor.

Eukaryotic translation initiation factor 2 subunit 3; eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S pre-initiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction cataly [...]

Eukaryotic translation initiation factor 2 subunit alpha (eIF2alpha) encodes one of three subunits of the eIF-2 complex required for the initiation of translation. eIF2alpha is classified as a 'Minute' gene as heterozygous mutants exhibit a slower developmental rate and small adult bristles.

Eukaryotic translation initiation factor 3 subunit B; RNA-binding component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is involved in protein synthesis of a specialized repertoire of mRNAs and, together with other initiation factors, stimulates binding of mRNA and methionyl-tRNAi to the 40S ribosome. The eIF-3 complex specifically targets and initiates translation of a subset of mRNAs involved in cell proliferation.

Eukaryotic translation initiation factor 5; Catalyzes the hydrolysis of GTP bound to the 40S ribosomal initiation complex (40S.mRNA.Met-tRNA[F].eIF-2.GTP) with the subsequent joining of a 60S ribosomal subunit resulting in the release of eIF-2 and the guanine nucleotide. The subsequent joining of a 60S ribosomal subunit results in the formation of a functional 80S initiation complex (80S.mRNA.Met-tRNA[F]) (By similarity).

Guanine nucleotide exchange factor MSS4 homolog; Guanine-nucleotide-releasing protein that acts on members of the sec4/ypt1/rab subfamily such as Rab8. During egg development, essential for establishing and maintaining epithelial cell polarity by regulating the correct polarized deposition of basal membrane (BM) proteins such as trol/Pcan and vkg/Coll IV to the basal surface of follicular epithelial (FE) cells. Likely to function by restricting the activity of the vesicle transport regulator Rab8 to the basal membrane, and thus directs BM protein-containing vesicles to the basal side o [...]
