EOL1 interacts with LHP1-PRC2 complexes during replication and thereby participates in maintaining the H3K27me3 mark at target genes.
a general role of LHP1 from local to higher conformation levels of chromatin configuration to determine its accessibility to define gene expression patterns
Neither PRC2 activity nor LHP1 function are a major determinant for H2A monoubiquitination in Arabidopsis thaliana.
that complexes of the transcription factors ASYMMETRIC LEAVES 1 (AS1) and AS2 could help to establish the H3K27me3 modification at the chromatin regions of Class-I KNOTTED1-like homeobox (KNOX) genes BREVIPEDICELLUS and KNAT2 via direct interactions with LHP1.
AIP1 interacts with ABAP1, with a plant histone modification "reader" (LHP1) and with non modified histones. Also, expression of ABAP1 and LHP1 target genes were repressed in flower buds of plants with reduced levels of AIP1.
Arabidopsis (Arabidopsis thaliana) GAGA-motif binding factor protein basic pentacysteine6 (BPC6) interacts with like heterochromatin protein1 (LHP1), a PRC1 component, and associates with vernalization2 (VRN2), a PRC2 component, in vivo.
MSI1 serves to link PRC2 to LIKE HETEROCHROMATIN PROTEIN 1 (LHP1), a protein that binds H3K27me3 in vitro and in vivo and is required for a functional polycomb group system.
TFL2 is required for normal seedling de-etiolation, greening and shade avoidance response through negative regulation of both PHYB-dependent R light signalling and PHYA-dependent FR light signalling.
CYP71 physically interacts with FAS1 and LHP1 to modulate their distribution on chromatin.
LIF2, involved in cell identity and cell fate decision, may modulate the activity of LHP1 at specific loci, during specific developmental windows or in response to environmental cues that control cell fate determination.[LIF2]
In vivo, TFL2 is targeted to a number of the YUCCA genes in an auxin-dependent fashion revealing a role of TFL2 in auxin regulation, probably as a component of protein complexes affecting transcriptional control.
We investigated the influence of heat stress on metabolites in the tu8 (a novel allele of TERMINAL FLOWER2) mutant. [TU8]
In transgenic plants expressing the LHP1-GFP fusion protein, two major localization patterns were observed according to cell types suggesting that localization evolves with age or differentiation states.
Results imply that LIKE HETEROCHROMATIN PROTEIN1 (LHP1) recruitment to chromatin is mediated through interaction with methyl K9 and that LHP1 controls different nuclear processes via transient binding to its nuclear sites.
chromodomain protein LIKE HETEROCHROMATIN PROTEIN (LHP)1 might play a role in vernalization
LIKE HETEROCHROMATIN PROTEIN 1 (LHP1) is necessary to maintain the epigenetically repressed state of FLC upon return to warm conditions typical of spring
LHP1, like its animal homologues, has a high binding affinity for A/T-rich regions.
Recognizes specifically trimethylated Histone H3 in vivo as part of a mechanism that represses the expression of many genes targeted by Polycomb repressive complex 2.
Arabidopsis thaliana chromodomain-containing protein LHP1 colocalizes with H3K27me3 genome-wide. The LHP1 chromodomain also binds H3K27me3 with high affinity, suggesting that LHP1 has functions similar to those of Polycomb
LHP1 acts together with SCR to suppress premature middle cortex formation.
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 and modification of histones, rendering chromatin heritably changed in its expressibility.
