STRINGSTRING
EXT3 protein (Arabidopsis thaliana) - STRING interaction network
"EXT3" - Extensin-3 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

EXT3Extensin-3; Structural component which strengthens the primary cell wall. Forms dendritic structures indicating a propensity for self-assembly through tyrosine cross-linking. Forms intermolecular cross- links exclusively by pulcherosine (three Tyr). Scaffold formation requires an unobstructed C-terminus of EXT3. Required for the correct positioning of the cell plate during cytokinesis in cells of the developing embryo. Extensins contain a characteristic repeat of the pentapeptide Ser-Pro(4). For this particular extensin, a typical repeat of Ser-Pro(3) is found (431 aa)

Unable to functionally complement E.coli relA mutants; Belongs to the RelA/SpoT family (884 aa)
           
  0.834
LRX1
Encodes a a chimeric leucine-rich repeat/extensin protein that regulates root hair morphogenesis and elongation. Null mutants develop root hairs that frequently abort, swell, or branch. Gene is expressed in root hair cells and protein is specifically localized in the wall of the hair proper (744 aa)

2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase superfamily protein; Catalyzes the post-translational formation of 4- hydroxyproline in -Xaa-Pro-Gly- sequences in proline-rich peptide sequences of plant glycoproteins and other proteins. Hydroxyprolines are important constituent of many plant cell wall glycoproteins such as extensins, hydroxyproline-rich glycoproteins, lectins and arabinogalactan proteins. Possesses high affinity for leucine-rich repeat and proline-rich extensins of root cell walls that are essential for root hair development. Hydroxyprolines define the subsequent O [...] (291 aa)
