STRINGSTRING
HO protein (Saccharomyces cerevisiae) - STRING interaction network
"HO" - Site-specific endonuclease required for gene conversion at the MAT locus (homothallic switching) through the generation of a ds DNA break 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

HOSite-specific endonuclease required for gene conversion at the MAT locus (homothallic switching) through the generation of a ds DNA break; expression restricted to mother cells in late G1 as controlled by Swi4p-Swi6p, Swi5p and Ash1p; Initiation of mating type interconversion. This protein is a site-specific endonuclease that cleaves a site in the mat locus on chromosome III. The double-strand break is followed by a unidirectional gene conversion event that replaces the information at the mat locus by information copied from either of the two homologous loci (HMR and HML) that reside a [...] (586 aa)    
Predicted Functional Partners:
TAD2
Subunit of tRNA-specific adenosine-34 deaminase, forms a heterodimer with Tad3p that converts adenosine to inosine at the wobble position of several tRNAs; Deaminates adenosine-34 to inosine in many tRNAs (250 aa)
         
  0.645
URA6
Uridylate kinase, catalyzes the seventh enzymatic step in the de novo biosynthesis of pyrimidines, converting uridine monophosphate (UMP) into uridine-5’-diphosphate (UDP); Catalyzes the phosphorylation of pyrimidine nucleoside monophosphates at the expense of ATP. Plays an important role in de novo pyrimidine nucleotide biosynthesis. Has preference for UMP and dUMP as phosphate acceptors, but can also use CMP, dCMP, AMP, GMP, dGMP and dTMP. ATP and dATP are the best phosphate donors, but can also use GTP, dGTP, dCTP, and dTTP to some degree (204 aa)
         
  0.626
ADK2
Mitochondrial adenylate kinase, catalyzes the reversible synthesis of GTP and AMP from GDP and ADP; may serve as a back-up for synthesizing GTP or ADP depending on metabolic conditions; 3’ sequence of ADK2 varies with strain background; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism. Adenylate kinase activity is critical for regulation of the phosphate utilization and the AMP de novo biosynthesis pathways (225 aa)
         
  0.626
ADK1
Adenylate kinase, required for purine metabolism; localized to the cytoplasm and the mitochondria; lacks cleavable signal sequence; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism. Adenylate kinase activity is critical for regulation of the phosphate utilization and the AMP de novo biosynthesis pathways (222 aa)

MPT5
Member of the Puf family of RNA-binding proteins; binds to mRNAs encoding chromatin modifiers and spindle pole body components; involved in longevity, maintenance of cell wall integrity, and sensitivity to and recovery from pheromone arrest; RNA-binding protein involved in post-transcriptional regulation. Negatively regulates expression of HO by binding to the 3’-UTR of HO mRNA. Predominantly binds to mRNAs encoding chromatin modifiers and spindle pole body components. Recognizes and binds to 5’-TGTAA[CT]A[AT]TA-3’ in the 3’-UTR of target mRNAs. Multicopy suppressor of POP2 mutation. R [...] (859 aa)
       
      0.621
PUF4
Member of the PUF protein family, which is defined by the presence of Pumilio homology domains that confer RNA binding activity; preferentially binds mRNAs encoding nucleolar ribosomal RNA-processing factors; Is not essential for haploid growth, but may affect diploid formation (888 aa)
       
      0.621
TRK2
Component of the Trk1p-Trk2p potassium transport system; This protein is required for low-affinity potassium transport (889 aa)
       
    0.620
TRK1
Component of the Trk1p-Trk2p potassium transport system; 180 kDa high affinity potassium transporter; phosphorylated in vivo and interacts physically with the phosphatase Ppz1p, suggesting Trk1p acitivy is regulated by phosphorylation; This protein is required for high-affinity potassium transport (1235 aa)

HAM1
Conserved protein with deoxyribonucleoside triphosphate pyrophosphohydrolase activity, mediates exclusion of noncanonical purines from deoxyribonucleoside triphosphate pools; mutant is sensitive to the base analog 6-N-hydroxylaminopurine; Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2’-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and 5-bromodeoxyuridine 5’-triphosphate (BrdUTP) to their respective monophosphate derivatives. Xanthosine 5’-triphosphate (XTP) is also a potential substrate [...] (197 aa)
