STRINGSTRING
BAS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"BAS1" - Myb-related transcription factor involved in regulating basal and induced expression of genes of the purine and histidine biosynthesis pathways 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

BAS1Myb-related transcription factor involved in regulating basal and induced expression of genes of the purine and histidine biosynthesis pathways; also involved in regulation of meiotic recombination at specific genes; Activates HIS4 transcription only in combination with PHO2/BAS2. BAS1 is also involved in the regulation of the purine biosynthesis pathway (811 aa)    
Predicted Functional Partners:
PHO2
Homeobox transcription factor; regulatory targets include genes involved in phosphate metabolism; binds cooperatively with Pho4p to the PHO5 promoter; phosphorylation of Pho2p facilitates interaction with Pho4p; Regulator in phosphate metabolism and acts as a derepressor of another central regulator PHO5. Binds to the upstream activator sequence (UAS) of PHO5. It also binds to the TRP4, HIS4, and CYC1 promoters (559 aa)

GCN4
bZIP transcriptional activator of amino acid biosynthetic genes; activator responds to amino acid starvation; expression is tightly regulated at both the transcriptional and translational levels; Is a transcription factor that is responsible for the activation of more than 30 genes required for amino acid or for purine biosynthesis in response to amino acid or purine starvation. Binds and recognize the DNA sequence- 5’-TGA[CG]TCA- 3’ (281 aa)

PRP22
DEAH-box RNA-dependent ATPase/ATP-dependent RNA helicase, associates with lariat intermediates before the second catalytic step of splicing; mediates ATP-dependent mRNA release from the spliceosome and unwinds RNA duplexes; Acts late in the splicing of pre-mRNA. Mediates the release of the spliced mRNA from spliceosomes (1145 aa)
     
 
  0.937
MSL5
Component of the commitment complex, which defines the first step in the splicing pathway; essential protein that interacts with Mud2p and Prp40p, forming a bridge between the intron ends; also involved in nuclear retention of pre-mRNA; Required for pre-spliceosome formation, which is the first step of pre-mRNA splicing. 2 commitment complexes, CC1 and CC2, have been defined. CC1 is a basal complex dependent only on the 5’-splice site. CC2 is a complex of lower mobility and is dependent on a branchpoint as well as a 5’-splice site region. This protein is involved in CC2 formation where [...] (476 aa)

PRP46
Member of the NineTeen Complex (NTC) that contains Prp19p and stabilizes U6 snRNA in catalytic forms of the spliceosome containing U2, U5, and U6 snRNAs; Involved in pre-mRNA splicing. May also be required for cell cycle progression at G2/M (By similarity) (451 aa)
     
 
  0.916
PRP19
Splicing factor associated with the spliceosome; contains a U-box, a motif found in a class of ubiquitin ligases, and a WD40 domain; Probable ubiquitin-protein ligase involved in pre-mRNA splicing. Acts as a central component of the NTC complex (or PRP19-associated complex) that associates to the spliceosome to mediate conformational rearrangement or to stabilize the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation. It is also probably involved in DNA repair (503 aa)
     
 
  0.895
ADE5,7
Enzyme of the ’de novo’ purine nucleotide biosynthetic pathway; contains aminoimidazole ribotide synthetase and glycinamide ribotide synthetase activities (802 aa)
           
  0.892
SHM2
Cytosolic serine hydroxymethyltransferase, converts serine to glycine plus 5,10 methylenetetrahydrofolate; major isoform involved in generating precursors for purine, pyrimidine, amino acid, and lipid biosynthesis; Interconversion of serine and glycine (469 aa)
       
 
  0.882
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)
     
 
  0.873
PRP3
Splicing factor, component of the U4/U6-U5 snRNP complex; Participates in pre-mRNA splicing. Part of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome (469 aa)
