STRINGSTRING
PARVUS protein (Arabidopsis thaliana) - STRING interaction network
"PARVUS" - Nucleotide-diphospho-sugar transferases superfamily protein 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

PARVUSNucleotide-diphospho-sugar transferases superfamily protein; The PARVUS/GLZ1 gene encodes a putative family 8 glycosyl transferase that contributes to xylan biosynthesis. Its gene expression shows good co-variance with the IRX3 gene involved in secondary cell wall synthesis. PARVUS/GLZ1 is predicted to have galacturonosyltransferase activity and may be involved in the formation of the complex oligosaccharide sequence present at the reducing end of xylan. PARVUS is expressed in cells undergoing secondary wall thickening, and parvus mutants have thinner cell walls (351 aa)    
Predicted Functional Partners:
FRA8
Probable glucuronoxylan glucuronosyltransferase IRX7; Homolog to AT5G22940, a member of glycosyltransferase family 47 that is involved in secondary cell wall biosynthesis. It exhibits high sequence similarity to tobacco (Nicotiana plumbaginifolia) pectin glucuronyltransferase. Protein has a domain that shares significant similarity with the pfam03016 domain. It is expressed specifically in developing vessels and fiber cells, and FRA8 is targeted to Golgi. Mutants have irregular xylem formation, reduced cellulose levels and plants are smaller than normal siblings (448 aa)
           
  0.967
IRX14
Nucleotide-diphospho-sugar transferases superfamily protein; The IRX14 gene encodes a putative family 43 glycosyl transferase that contributes to xylan biosynthesis. It was identified based on its gene expression co-variance with the IRX3 gene involved in secondary cell wall synthesis. A biochemical assay using the irx14 mutant indicates that IRX14 might function in xylose chain elongation (525 aa)
           
  0.953
IRX9
Nucleotide-diphospho-sugar transferases superfamily protein; The IRX9 gene encodes a putative family 43 glycosyl transferase. It was coordinately expressed with the cellulose synthase subunits during secondary cell wall formation. Cell wall analysis revealed a decrease in the abundance of xylan in the irx9 mutant, indicating that IRX9 is required for xylan synthesis. Mutants have irregular xylem phenotype suggesting a role in secondary cell wall biosynthesis; Belongs to the glycosyltransferase 43 family (351 aa)
           
  0.953
GUT1
Probable beta-1,4-xylosyltransferase IRX10L; Involved in the synthesis of the hemicellulose glucuronoxylan, a major component of secondary cell walls. Probably involved in the elongation of glucuronoxylan xylosyl backbone (415 aa)
           
  0.952
GUT2
Probable beta-1,4-xylosyltransferase IRX10; Involved in the synthesis of the hemicellulose glucuronoxylan, a major component of secondary cell walls. Probably involved in the elongation of glucuronoxylan xylosyl backbone, especially in the formation of GlcUA side chain of xylans (412 aa)
           
  0.952
IRX14-L
Nucleotide-diphospho-sugar transferases superfamily protein; Encodes a member of the GT43 family glycosyltransferases involved in glucuronoxylan biosynthesis- AT2G37090 (IRX9) and AT1G27600 (IRX9-L or I9H, IRX9 homolog); AT4G36890 (IRX14) and AT5G67230 (IRX14-L or I14H, IRX14 homolog). They form two functionally non-redundant groups essential for the normal elongation of glucuronoxylan backbone. I9H functions redundantly with IRX9, I14H is redundant with IRX14. IRX9 or I9H do not complement IRX14, IRX14 or I14H do not complement IRX9 (492 aa)
           
  0.951
F8H
Probable glucuronoxylan glucuronosyltransferase F8H; Involved in the synthesis of the hemicellulose glucuronoxylan, a major component of secondary cell walls. Probably involved in the synthesis of the glycosyl sequence at the glucuronoxylan reducing end; Belongs to the glycosyltransferase 47 family (469 aa)
           
  0.928
PGSIP1
UDP-glucuronate-xylan alpha-glucuronosyltransferase 1; Glycosyltransferase required for the addition of both glucuronic acid and 4-O-methylglucuronic acid branches to xylan in stem cell walls. In association with GUX2, is responsible for almost all of the substitutions of the xylan backbone in stem glucuronoxylan; Belongs to the glycosyltransferase 8 family. Glycogenin subfamily (659 aa)
           
  0.895
IRX9-L
Nucleotide-diphospho-sugar transferases superfamily protein; Encodes a member of the GT43 family glycosyltransferases involved in glucuronoxylan biosynthesis- AT2G37090 (IRX9) and AT1G27600 (IRX9-L or I9H, IRX9 homolog); AT4G36890 (IRX14) and AT5G67230 (IRX14-L or I14H, IRX14 homolog). They form two functionally non-redundant groups essential for the normal elongation of glucuronoxylan backbone. I9H functions redundantly with IRX9, I14H is redundant with IRX14. IRX9 or I9H do not complement IRX14, IRX14 or I14H do not complement IRX9 (394 aa)

Protein of unknown function (DUF579); Required for xylan biosynthesis, but not directly involved in catalyzing the addition of sugars to the growing polymer (322 aa)
