STRINGSTRING
RCAR1 protein (Arabidopsis thaliana) - STRING interaction network
"RCAR1" - Abscisic acid receptor PYL9 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

RCAR1Abscisic acid receptor PYL9; Receptor for abscisic acid (ABA) required for ABA- mediated responses such as stomatal closure and germination inhibition. Inhibits the activity of group-A protein phosphatases type 2C (PP2Cs) in an ABA-independent manner but more efficiently when activated by ABA. Confers enhanced sensitivity to ABA (PubMed-19407143, PubMed-23844015, PubMed-21658606). Can be activated only by (+)-ABA but not by (-)-ABA (PubMed-23844015) (187 aa)    
Predicted Functional Partners:
HAB1
HYPERSENSITIVE TO ABA1; Key component and repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, seed germination and inhibition of vegetative growth. Confers enhanced sensitivity to drought (511 aa)
       
  0.999
HAI2
Protein phosphatase 2C 3; Involved in the negative regulation of the K(+) potassium channel AKT1 by its dephosphorylation, antagonistically to CIPK proteins (e.g. CIPK23) (442 aa)
       
  0.999
HAI3
Highly ABA-induced PP2C gene 3 (362 aa)
       
  0.999
HAI1
Protein phosphatase (413 aa)
       
  0.999
PYL13
PYR1-like 13; Receptor for abscisic acid (ABA) required for ABA- mediated responses such as stomatal closure and germination inhibition (By similarity). Inhibits the activity of group-A protein phosphatases type 2C (PP2Cs), selectively PP2CA, in an ABA-independent manner (PubMed-24165892) (164 aa)
       
 
0.996
PP2CA
Protein phosphatase 2CA; Major negative regulator of abscisic acid (ABA) responses during seed germination and cold acclimation. Confers insensitivity to ABA. Modulates negatively the AKT2/3 activity, which mediates K(+) transport and membrane polarization during stress situations, probably by dephosphorylation. Prevent stomata closure by inactivating the S-type anion efflux channel SLAC1 and its activator SRK2E (399 aa)
       
  0.992
ABI1
ABA INSENSITIVE 1; Key component and repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, osmotic water permeability of the plasma membrane (Pos), drought-induced resistance and rhizogenesis, response to glucose, high light stress, seed germination and inhibition of vegetative growth. During the stomatal closure regulation, modulates the inward calcium-channel permeability as well as the actin reorganization in guard cells in response to ABA. Involved in the resistance to the bacterial pathogen Pseudomonas syringae pv. [...] (434 aa)
       
  0.989
ABI2
ABA INSENSITIVE 2; Repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, osmotic water permeability of the plasma membrane (Pos), high light stress, response to glucose, seed germination and inhibition of vegetative growth. During the stomatal closure regulation, modulates the inward calcium-channel permeability as well as H(2)O(2) and oxidative burst in response to ABA and dehydration. Controls negatively fibrillin that is involved in mediating ABA- induced photoprotection. May be implicated in ABA content regulation. I [...] (423 aa)

AHG1
Protein phosphatase; Negative regulator of abscisic acid (ABA) responses during seed germination (416 aa)

HAB2
Homology to ABI2; Key component and repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, seed germination and inhibition of vegetative growth (511 aa)
