Eukaryotic Initiation factor 6

We investigated the effect of endoplasmic reticulum (ER) protein 29 (ERp29) on thyroglobulin (Tg) secretion and its negative regulation by microRNAs (miRNAs). ERp29 overexpression promoted Tg secretion from thyrocytes of PCCL3 cells via activation of ER stress sensors, including activation of transcription factor 6 fragmentation, XBP1 mRNA splicing by inositol-requiring enzyme 1, and phosphorylation of eukaryotic initiation factor 2 alpha as downstream actions of RNA-dependent protein kinase-like ER kinase.

Eukaryotic Initiation factor 6 (eIF6) is a peculiar translation initiation factor that binds to the large 60S ribosomal subunits, controlling translation initiation and participating in ribosome biogenesis.

Eukaryotic translation initiation factor 5A (eIF5A) is the only cellular protein that contains the unusual amino acid hypusine [N e -(4-amino-2-hydroxybutyl)lysine]. Vertebrates carry two genes that encode two eIF5A isoforms, eIF5A-1 and eIF5A-2, which, in humans, are 84% identical. eIF5A-1 mRNA (1.3 kb) and protein (18 kDa) are constitutively expressed in human cells. In contrast, expression of eIF5A-2 mRNA (0.7–5.6 kb) and eIF5A-2 protein (20 kDa) varies widely.
