A RanBP1 mutation which does not visibly affect nuclear import may reveal additional functions of the ran GTPase system.

Experimental cell research - 10 Oct 1998

Ouspenski I I

Abstract excerpt

Ran, a nuclear GTPase, and a number of interacting proteins, including regulators RanGEF1 and RanGAP1, are involved in nucleocytoplasmic transport. We have identified a new temperature-sensitive mutation in budding yeast YRB1 gene, which encodes Ran-binding protein-1 (RanBP1). In contrast to other yrb1 alleles, the new mutation (yrb1-21) does not cause visible defects in import of nuclear proteins Npl3p, histone...
