FunctionBinds to the 60S ribosomal subunit and prevents its association with the 40S ribosomal subunit to form the 80S initiation complex in the cytoplasm. May behave as a stimulatory translation initiation factor downstream insulin/growth factors. Is 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 (GNB2L1)-dependent protein kinase C activity.
Tissue specificityExpressed at very high levels in colon carcinoma with lower levels in normal colon and ileum and lowest levels in kidney and muscle (at protein level).
Sequence similaritiesBelongs to the eIF-6 family.
Post-translational modificationsPhosphorylation at Ser-174 and Ser-175 promotes nuclear export.
Cellular localizationCytoplasm. Nucleus > nucleolus. Shuttles between cytoplasm and nucleus/nucleolus.
