WebApr 8, 2015 · Furthermore, eIF6 interacts in the cytoplasm with RACK1, a receptor for activated protein kinase C (PKC). RACK1 is a major component of translating ribosomes, which harbour significant amounts of PKC. Loading 60S subunits with eIF6 caused a dose-dependent translational block and impairment of 80S formation, which were reversed by … WebMammalian 36-kDa RACK1 binds the active form of protein kinase C (PKC) and associates with the 40S ribosomal subunit near the mRNA exit channel to regulate translation [4-6]. RACK1 serves as a physical and functional link between PKC-mediated eukaryotic initiation factor 6 (eIF6) phosphorylation and subsequent ribosome activation [4, 5].

WebIs also involved in ribosome biogenesis. Associates with pre-60S subunits in the nucleus and is involved in its nuclear export. Cytoplasmic release of TIF6 from 60S subunits and nuclear relocalization is promoted by a RACK1 (RACK1)-dependent protein kinase C activity (PubMed:10085284, PubMed:14654845, PubMed:21536732).
