STRINGSTRING
YRA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"YRA1" - RNA binding protein required for export of poly(A)+ mRNA from the nucleus 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

YRA1RNA binding protein required for export of poly(A)+ mRNA from the nucleus; proposed to couple mRNA export with 3’ end processing via its interactions with Mex67p and Pcf11p; functionally redundant with Yra2p, another REF family member; RNA-binding RNA annealing protein. May have a role in pre-mRNA metabolism. Component the TREX complex, which operates in coupling transcription elongation to mRNA export (226 aa)    
Predicted Functional Partners:
SUB2
Component of the TREX complex required for nuclear mRNA export; member of the DEAD-box RNA helicase superfamily and is involved in early and late steps of spliceosome assembly; homolog of the human splicing factor hUAP56; ATP-binding RNA helicase component of the TREX complex involved in transcription elongation and required for the export of mRNA out of the nucleus. SUB2 plays also a role in pre-mRNA splicing and spliceosome assembly. May be involved in rDNA and telomeric silencing, and maintenance of genome integrity (446 aa)
