STRINGSTRING
KAP104 protein (Saccharomyces cerevisiae) - STRING interaction network
"KAP104" - Transportin or cytosolic karyopherin beta 2 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

KAP104Transportin or cytosolic karyopherin beta 2; functions in the rg-nuclear localization signal-mediated nuclear import/reimport of mRNA-binding proteins Nab2p and Hrp1p; regulates asymmetric protein synthesis in daughter cells during mitosis; Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for arginine/glycine-rich nuclear localization signals (rg-NLS) and PY-NLS in cargo substrates. Its predominant cargo substrate seems to be mRNA-binding proteins. Required for nuclear transport of NAB2, HRP1/NAB4 and TFG2. Mediates docking of the importin/substrate [...] (918 aa)    
Predicted Functional Partners:
KAP123
Karyopherin beta, mediates nuclear import of ribosomal proteins prior to assembly into ribosomes and import of histones H3 and H4; localizes to the nuclear pore, nucleus, and cytoplasm; exhibits genetic interactions with RAI1; Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates. Its predominant cargo substrate seems to be ribosomal proteins (PubMed-9321403). Required for import of the ribbosomal assembly factor NMD3 (PubMed-12612077). May be involved in nuclear transport of YAP1 (PubMed-1127414 [...] (1113 aa)

PSE1
Karyopherin/importin that interacts with the nuclear pore complex; acts as the nuclear import receptor for specific proteins, including Pdr1p, Yap1p, Ste12p, and Aft1p; Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for classical and arginine/glycine- rich nuclear localization signals (cNLS and rg-NLS) in cargo substrates (PubMed-15367670). Its predominant cargo substrate seems to be ribosomal proteins and ribosome biogenesis trans- and cis-acting factors (PubMed-9182759, PubMed-9321403, PubMed-15367670). Required for nuclear transport of YAP1, NO [...] (1089 aa)

MTR10
Nuclear import receptor, mediates the nuclear localization of proteins involved in mRNA-nucleus export; promotes dissociation of mRNAs from the nucleus-cytoplasm mRNA shuttling protein Npl3p; required for retrograde import of mature tRNAs; Involved in mRNA transport from nucleus to cytoplasm (972 aa)

GSP1
Ran GTPase, GTP binding protein (mammalian Ranp homolog) involved in the maintenance of nuclear organization, RNA processing and transport; regulated by Srm1p, Rna1p, Yrb1p, Yrb2p, Yrp4p, Yrb30p, Cse1p and Kap95p; yeast Gsp2p homolog; GTP-binding protein involved in nucleocytoplasmic transport. Required for the import of protein into the nucleus and also for RNA export. Essential for cell viability. By analogy with Ras, Ran may be activated when GTP is exchanged for bound GDP by RCC1 and inactivated when GTP is hydrolyzed by Ran upon activation by RanGAP1 (219 aa)

It may be involved not only in RNA processing but also in transcription regulation. Believed to associate directly with nascent RNA polymerase II transcripts and remain associated during subsequent nuclear RNA processing reactions (525 aa)
