RING1B protein (Arabidopsis thaliana) - STRING interaction network
"RING1B" - Putative E3 ubiquitin-protein ligase RING1b in Arabidopsis thaliana
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 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
protein homology

Gene Fusion
RING1BPutative E3 ubiquitin-protein ligase RING1b; Encodes a nuclear localized protein with similarity to animal polycomb repressive core complex1 (PRC1) core component RING.Appears to function redundantly with ATRING1a, a close paralog. Both interact physically with CLF and LHP1 and appear to function together to repress class I KNOX gene expression (468 aa)    
Predicted Functional Partners:
E3 ubiquitin protein ligase DRIP2; E3 ubiquitin-protein ligase that acts as a negative regulator of the response to water stress. Mediates ubiquitination and subsequent proteasomal degradation of the drought-induced transcriptional activator DREB2A. Functionally redundant with DRIP1 (420 aa)
Probable E3 ubiquitin protein ligase DRIPH; RING/U-box superfamily protein; Its function is described as zinc ion binding; Expressed in central cell, flower; Expressed during 4 anthesis; Contains the following InterPro domains- Zinc finger, RING-type, conserved site (InterPro-IPR017907), Zinc finger, RING-type (InterPro-IPR001841), Zinc finger, C3HC4 RING-type (InterPro-IPR018957); BEST Arabidopsis thaliana protein match is- DREB2A-interacting protein 2 (TAIR-AT2G30580.1); Has 1905 Blast hits to 1881 proteins in 164 species- Archae - 0; Bacteria - 4; Metazoa - 1370; Fungi - 69; Plants [...] (480 aa)
Histone-lysine N-methyltransferase CLF; Polycomb group (PcG) protein. Catalytic subunit of some PcG multiprotein complex, which methylates ’Lys-27’ of histone H3, leading to transcriptional repression of the affected target genes. Required to regulate floral development by repressing the AGAMOUS homeotic gene in leaves, influorescence stems and flowers. Regulates the antero-posterior organization of the endosperm, as well as the division and elongation rates of leaf cells. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressiv [...] (902 aa)
Histone-lysine N-methyltransferase EZA1; Encodes a polycomb group protein. Forms part of a large protein complex that can include VRN2 (VERNALIZATION 2), VIN3 (VERNALIZATION INSENSITIVE 3) and polycomb group proteins FERTILIZATION INDEPENDENT ENDOSPERM (FIE) and CURLY LEAF (CLF). The complex has a role in establishing FLC (FLOWERING LOCUS C) repression during vernalization. Performs a partially redundant role to MEA in controlling seed initiation by helping to suppress central cell nucleusendosperm proliferation within the FG (856 aa)
Chromo domain-containing protein LHP1; Structural component of heterochromatin involved in gene repression, including several floral homeotic genes and FLT that regulates flowering time. Required for maintenance of vernalization-induced repression of FLC. As part of the PRC1-like complex, recognizes and binds histone H3 tails methylated at ’Lys- 9’ (H3K9me) and ’Lys-27’ (H3K27me), leading to epigenetic repression. PcG PRC1 complex maintains the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling a [...] (445 aa)
Encodes HTA4, a histone H2A protein (124 aa)
Encodes a RING finger domain protein with E3 ligase activity that is localized to the lipid rafts of the plasma membrane. Expression is increased in response to fungal pathogen. May be involved in regulation of programmed cell death by facilitating degredation of regulation of PDC activators; Belongs to the RING-type zinc finger family. ATL subfamily (301 aa)
Encodes a protein similar to the transcriptional regular of the animal Polycomb group and is involved in regulation of establishment of anterior-posterior polar axis in the endosperm and repression of flowering during vegetative phase. Mutation leads endosperm to develop in the absence of fertilization and flowers to form in seedlings and non-reproductive organs. Also exhibits maternal effect gametophytic lethal phenotype, which is suppressed by hypomethylation. Forms part of a large protein complex that can include VRN2 (VERNALIZATION 2), VIN3 (VERNALIZATION INSENSITIVE 3) and polyco [...] (369 aa)
