NOVEL NUCLEOLAR PROTEIN

摘要

A full-length cDNA encoding a novel nucleolar protein which is successfully isolated by screening a fetal human brain cDNA library with the use of a partial cDNA encoding a peptide having a nuclear transport activity isolated by using a yeast nuclear transport trap system (NTT) developed originally. Also, a region necessary for the nucleolar transport activity and a region for the nuclear transport activity of the above protein are identified.
