STRINGSTRING
ARA-2 protein (Arabidopsis thaliana) - STRING interaction network
"ARA-2" - Ras-related small GTP-binding family 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

ARA-2Ras-related small GTP-binding family protein; Involved in auxin-mediated response. May be involved in vesicle trafficking of components involved in polar auxin transport. Binds GTP and GDP and possesses intrinsic GTPase activity (216 aa)    
Predicted Functional Partners:
REP
Rab escort protein 1; Substrate-binding subunit of the Rab geranylgeranyltransferase (GGTase) complex. Binds unprenylated Rab proteins and presents the substrate peptide to the catalytic component composed of the alpha subunit RGTA and the beta subunit RGTB (Probable). Preferentially binds the GDP-bound form of Rab and stimulates geranylgeranylation of various Rab GTPases in vitro (563 aa)

RABH1e
Ras-related protein RABH1e; Protein transport. Regulator of membrane traffic from the Golgi apparatus towards the endoplasmic reticulum (ER) (By similarity) (207 aa)
   
0.939
RAB6A
Ras-related small GTP-binding family protein; Protein transport. Regulator of membrane traffic from the Golgi apparatus towards the endoplasmic reticulum (ER). Binds GTP and GDP and possesses intrinsic GTPase activity (By similarity); Belongs to the small GTPase superfamily. Rab family (208 aa)
   
0.937
ARA7
Ras-related small GTP-binding family protein; Endosomal protein that may be involved in endocytosis. Involved in the trafficking of proteins from prevacuolar compartments (PVCs) to vacuoles. May activate the MON1-CCZ1 complex which acts as guanine nucleotide exchange factors (GEF) for Rab7 protein family, and serves as a link between Rab5 and Rab7 families in PVCs, and mediates PVC maturation. Involved in vacuolar transport of storage proteins with EREX as effector. Regulates membrane trafficking to protein storage vacuoles (PSVs); Belongs to the small GTPase superfamily. Rab family (200 aa)
