General annotation (Comments)
| Function | Nuclear chaperone required for maturation and nuclear export of pre-60S ribosome subunits. Functions at successive maturation steps to remove ribosomal factors at critical transition points, first driving the exit of early pre-60S particles from the nucleolus and then driving late pre-60S particles from the nucleus. Mediates ATP-dependent remodeling of the pre-ribosome just prior to export to allow maturation of 60S subunits into export-competent particles. Removes the ribosome biogenesis factor RSA4 from pre-60S ribosomal subunits in the nucleoplasm to drive nuclear export of the subunit. Involved in 3' processing of the 5.8S rRNA. Ref.7 Ref.8 Ref.11 Ref.12 |
| Subunit structure | Associates with pre-60S ribosomes in the nucleoplasm. Interacts with RSA4 and YTM1. Ref.3 Ref.5 Ref.8 Ref.11 Ref.12 |
| Subcellular location | |
| Miscellaneous | Present with 538 molecules/cell in log phase SD medium. |
| Sequence similarities | Belongs to the midasin family. Contains 1 VWFA domain. |
