Nucleo-cytoplasmic Transport Across the Nuclear Pores
Current Research
The nuclear pore complex is one of the largest structural
organelles within the eukaryotic cell. About 30 individual nucleoporins
constitute the yeast NPC. About half of these nucleoporins were
identified in my laboratory by genetic and biochemical methods.
Several nucleoporins were isolated in stable association with
each other and thus represent sucomplexes of the nuclear pore
complex. The Nup84p complex composed of six subunits has functions
both in pore biogenesis and in mRNA transport processes. By a
genetic screen using a mutant of the Nup84p complex, we have
found the Mex67p/Mtr2p complex and its mammalian TAP/p15 counterpart,
and shown that these complexes act as a shuttling receptor for
nuclear mRNA export.
Projects for a doctoral thesis
1. Study the mechanism of nuclear mRNA export. Our model system
consists of the essential and evolutionary conserved mRNA exporter
complex, the Mex67p/Mtr2p heterodimer, which is both linked to
nucleoporins and upstream factors involved in pre-mRNA biogenesis.
2. Study the mechanism of ribosomal export. We have isolated
20 rix (ribosomal export) mutants. The genes
of these rix ts mutants are currently cloned. By this
way, one can identify the factors involved in ribosomal subunit
export from the nucleus into the cytoplasm.
3. Reconstitution of nuclear pore proteins in NPC subcomplexes
and determination of their structure and interaction with shuttling
transport receptors
