UGT80B1 protein (Arabidopsis thaliana) - STRING interaction network
"UGT80B1" - Sterol 3beta-glucosyltransferase in Arabidopsis thaliana
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

UGT80B1Sterol 3beta-glucosyltransferase; Involved in the biosynthesis of sterol glucosides. Catalyzes the synthesis of steryl glycosides (SGs) and acyl steryl glycosides (ASGs) which are the most abundant sterol derivatives in higher plants. Can act on several sterols like sitosterol, campesterol and stigmasterol. Is required for embryonic development, seed suberin accumulation, cutin formation and flavanoid accumulation in the seed coat. Both UGT80A2 and UGT80B1 are required for the normal production of SGs and ASGs in seeds (615 aa)    
Predicted Functional Partners:
TT10
Laccase-15; Lignin degradation and detoxification of lignin-derived products (By similarity). Involved in lignin synthesis in seed coats, in seed coat permeability, in seed germination, and in root elongation. Required for the seed coat (testa) brown pigmentation by mediating the polymerization of proanthocyanidin (tannin) from its monomer precursor epicatechin. Promotes sligthly seed dormancy (565 aa)
           
  0.861
TT12
TRANSPARENT TESTA 12; Acts as a flavonoid/H(+)-antiporter that control the vacuolar sequestration of flavonoids in the seed coat endothelium (PubMed-11283341, PubMed-17601828). Could transport the anthocyanin cyanidin-3-O-glucoside (PubMed-17601828) and epicatechin 3’-O-glucoside (PubMed-19684242) in vitro (507 aa)
           
  0.740
TT1
Transparent testa 1; May act as a transcriptional regulator involved in the differentiation of young endothelium. Altered differentiation results in incompetence for pigments synthesis and the lack of condensed tannins in the seed coat (PubMed-21477081). Plays a role in the regulatory network controlling flavonoid accumulation in endothelium cells during seed development (PubMed-21477081) (303 aa)
           
  0.740
AT2G19880
Nucleotide-diphospho-sugar transferases superfamily protein (520 aa)
           
  0.715
TT7
TRANSPARENT TESTA 7; Catalyzes the 3’-hydroxylation of the flavonoid B-ring to the 3’,4’-hydroxylated state. Convert naringenin to eriodictyol and dihydrokaempferol to dihydroquercetin (513 aa)
     
 
  0.701
BAN
BANYULS; Involved in the biosynthesis of condensed tannins. Converts cyanidin into (-)-epicatechin as the major product (340 aa)
         
  0.641
UNE2
Putative transporter (490 aa)
           
  0.637
AT1G15160
MATE efflux family protein (487 aa)
           
  0.635
TT8
TRANSPARENT TESTA 8; Transcription activator, when associated with MYB75/PAP1 or MYB90/PAP2. Involved in the control of flavonoid pigmentation. Plays a key role in regulating leucoanthocyanidin reductase (BANYULS) and dihydroflavonol-4-reductase (DFR). Not required for leucoanthocyanidin dioxygenase (LDOX) expression (518 aa)
           
  0.634
TT16
TRANSPARENT TESTA16; Transcription factor involved in the developmental regulation of the endothelium and in the accumulation of proanthocyanidins (PAs) or condensed tannins which give the seed its brown pigmentation after oxidation. Necessary for the normal activation of the BANYULS promoter in the endothelium body (252 aa)
