STRINGSTRING
IWR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"IWR1" - RNA polymerase II transport factor, conserved from yeast to humans in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

IWR1RNA polymerase II transport factor, conserved from yeast to humans; involved in both basal and regulated transcription from RNA polymerase II (RNAP II) promoters, but not itself a transcription factor; interacts with most of the RNAP II subunits; nu /.../ytoplasmic shuttling protein; deletion causes hypersensitivity to K1 killer toxin; Directs RNA polymerase II nuclear import. Binds RNA polymerase II in the active center cleft between the two largest subunits in the cytoplasm. Then uses an N-terminal bipartite nuclear localization signal that may be recognized by karyopherin alpha to d [...] (353 aa)
