STRINGSTRING
HUB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"HUB1" - Ubiquitin-like protein modifier 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

HUB1Ubiquitin-like protein modifier; promotes alternative splicing of SRC1 pre-mRNA; binds non-covalently to the HIND domain of Snu66, may function in modification of Sph1p and Hbt1p, functionally complemented by the human or S. pombe ortholog; mechanis /.../ub1p adduct formation not yet clear; Forms conjugate with SPH1 and HBT1. Involved in morphogenesis (73 aa)    
Predicted Functional Partners:
SNU66
Component of the U4/U6.U5 snRNP complex involved in pre-mRNA splicing via spliceosome; also required for pre-5S rRNA processing and may act in concert with Rnh70p; has homology to human SART-1; Component of the U4/U6.U5 tri-snRNP particle, one of the building blocks of the spliceosome. Required for pre-mRNA splicing (587 aa)
       
 
  0.999
BRR2
RNA-dependent ATPase RNA helicase (DEIH box); required for disruption of U4/U6 base-pairing in native snRNPs to activate the spliceosome for catalysis; homologous to human U5-200kD; RNA helicase that plays an essential role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes. Involved in spliceosome assembly, activation and disassembly. Mediates changes in the dynamic network of RNA-RNA interactions in the spliceosome. Catalyzes the ATP-dependent unwinding of U4/U6 RNA duplices, an essential step in the assembly of a catalytically active spliceosome (2163 aa)

IST3
Component of the U2 snRNP, required for the first catalytic step of splicing and for spliceosomal assembly; interacts with Rds3p and is required for Mer1p-activated splicing; Required for pre-mRNA splicing and spliceosome assembly. As part of the pre-mRNA retention and splicing (RES) complex, required for nuclear pre-mRNA retention and efficient splicing. Required for MER1-activated splicing (148 aa)

PRP8
Component of the U4/U6-U5 snRNP complex, involved in the second catalytic step of splicing; mutations of human Prp8 cause retinitis pigmentosa; Functions as a scaffold that mediates the ordered assembly of spliceosomal proteins and snRNAs. Required for association of BRR2 with the spliceosomal U5 snRNP, and the subsequent assembly of the U4/U6-U5 tri-snRNP complex. Functions as scaffold that positions spliceosomal U2, U5 and U6 snRNAs at splice sites on pre-mRNA substrates, so that splicing can occur. Interacts with both the 5’ and the 3’ splice site, as well as the branch region. Has [...] (2413 aa)

RUB1
Ubiquitin-like protein with similarity to mammalian NEDD8; conjugation (neddylation) substrates include the cullins Cdc53p, Rtt101p, and Cul3p; activated by Ula1p and Uba3p (E1 enzyme pair); conjugation mediated by Ubc12p (E2 enzyme); Ubiquitin-like protein modifier that can be covalently attached to lysine residues of target proteins. Activated by the dimeric UBA3-ULA1 E1 enzyme and conjugated by the E2 UBC12 to substrate proteins. RUB1-conjugated (neddylated) substrate proteins include the cullins CDC53, RTT101 and CUL3, and the modification enhances the ubiquitin-ligase activity of [...] (77 aa)
