- Activation of the mRNA upon binding of the cap-binding complex and eIFs, and subsequent binding to 43S, organism-specific biosystem (from REACTOME)
Activation of the mRNA upon binding of the cap-binding complex and eIFs, and subsequent binding to 43S, organism-specific biosystemThe cap-binding complex is constituted by the initiation factors eIF4A, eIF4G and eIF4E. First, eIF4E must be released from the inactive eIF4E:4E-BP complex. Then eIF4A interacts with eIF4G, and eIF...
- Cap-dependent Translation Initiation, organism-specific biosystem (from REACTOME)
Cap-dependent Translation Initiation, organism-specific biosystemTranslation initiation is a complex process in which the Met-tRNAi initiator, 40S, and 60S ribosomal subunits are assembled by eukaryotic initiation factors (eIFs) into an 80S ribosome at the start c...
- Eukaryotic Translation Initiation, organism-specific biosystem (from REACTOME)
Eukaryotic Translation Initiation, organism-specific biosystemInitiation of translation in the majority of eukaryotic cellular mRNAs depends on the 5'-cap (m7GpppN) and involves ribosomal scanning of the 5' untranslated region (5'-UTR) for an initiating AUG sta...
- Formation of a pool of free 40S subunits, organism-specific biosystem (from REACTOME)
Formation of a pool of free 40S subunits, organism-specific biosystemThe 80S ribosome dissociates into free 40S (small) and 60S (large) ribosomal subunits. Each ribosomal subunit is constituted by several individual ribosomal proteins and rRNA.
- Formation of the ternary complex, and subsequently, the 43S complex, organism-specific biosystem (from REACTOME)
Formation of the ternary complex, and subsequently, the 43S complex, organism-specific biosystemBinding of the methionyl-tRNA initiator to the active eIF2:GTP complex results in the formation of the ternary complex. Subsequently, this Met-tRNAi:eIF2:GTP (ternary) complex binds to the complex fo...
- GTP hydrolysis and joining of the 60S ribosomal subunit, organism-specific biosystem (from REACTOME)
GTP hydrolysis and joining of the 60S ribosomal subunit, organism-specific biosystemHydrolysis of eIF2-GTP occurs after the Met-tRNAi has recognized the AUG. This reaction is catalyzed by eIF5 (or eIF5B) and is thought to cause dissociation of all other initiation factors and allow ...
- Gene Expression, organism-specific biosystem (from REACTOME)
Gene Expression, organism-specific biosystemGene Expression covers the pathways by which genomic DNA is transcribed to yield RNA, the regulation of these transcription processes, and the pathways by which newly-made RNA Transcripts are process...
- L13a-mediated translational silencing of Ceruloplasmin expression, organism-specific biosystem (from REACTOME)
L13a-mediated translational silencing of Ceruloplasmin expression, organism-specific biosystemWhile circularization of mRNA during translation initiation is thought to contribute to an increase in the efficiency of translation, it also appears to provide a mechanism for translational silencin...

Metabolism of proteins, organism-specific biosystemProtein metabolism comprises the pathways of translation, post-translational modification and protein folding.
- RNA transport, organism-specific biosystem (from KEGG)
RNA transport, organism-specific biosystemRNA transport from the nucleus to the cytoplasm is fundamental for gene expression. The different RNA species that are produced in the nucleus are exported through the nuclear pore complexes (NPCs) ...

- Ribosomal scanning and start codon recognition, organism-specific biosystem (from REACTOME)
Ribosomal scanning and start codon recognition, organism-specific biosystemThe 80S ribosome bound to the mRNA moves along the mRNA molecule from its initial site to the initiation codon and forms a 48S complex, in which the initiation codon is base paired to the anticodon o...

TGF-beta Receptor Signaling Pathway, organism-specific biosystem"The TGF beta receptors TGFBR1 and TGFBR2 belong to a subfamily of membrane-bound serine/threonine kinases which are designated as Type I or II based on their structural and functional properties. Th...
- Translation, organism-specific biosystem (from REACTOME)
Translation, organism-specific biosystemProtein synthesis is accomplished through the process of translation of an mRNA sequence into a polypeptide chain. This process can be divided into three distinct stages: initiation, elongation and ...
- Translation Factors, organism-specific biosystem (from WikiPathways)
Translation Factors, organism-specific biosystemProtein synthesis is the ultimate step of gene expression and a key control point for regulation. In particular, it enables cells to rapidly manipulate protein production without new mRNA synthesis, ...
