STRINGSTRING
ph-p protein (fruit fly) - STRING interaction network
"ph-p" - Polyhomeotic proximal in Drosophila melanogaster
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

ph-pPolyhomeotic proximal; Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A ’Lys-118’, rendering chromatin heritably changed in its expressibility. Plays a role in regulatin [...] (1589 aa)    
Predicted Functional Partners:
Scm
Sex comb on midleg; Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility (877 aa)

Sce
Protein binding; E3 ubiquitin-protein ligase that mediates monoubiquitination of ’Lys-118’ of histone H2A, thereby playing a central role in histone code and gene regulation. H2A ’Lys-118’ ubiquitination gives a specific tag for epigenetic transcriptional repression. Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. PcG complexes act via [...] (435 aa)

Polycomb; Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A ’Lys-118’, rendering chromatin heritably changed in its expressibility. Promotes locus-specific chromatin compaction (390 aa)

Psc
Posterior sex combs; Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A ’Lys-118’, rendering chromatin heritably changed in its expressibility.

Su(z)2
DNA binding; Regulates expression of the homeotic selector genes by influencing higher-order chromatin structure through interaction with other proteins (1396 aa)

esc
Extra sexcombs; Polycomb group (PcG) protein. While PcG proteins are generally required to maintain the transcriptionally repressive state of homeotic genes throughout development, this protein is specifically required during the first 6 hours of embryogenesis to establish the repressed state. Component of the Esc/E(z) complex, which methylates ’Lys-9’ and ’Lys-27’ residues of histone H3, leading to transcriptional repression of the affected target gene. The Esc/E(z) complex is necessary but not sufficient for the repression of homeotic target genes, suggesting that the recruitment of [...] (425 aa)

E(z)
Enhancer of zeste; Polycomb group (PcG) protein. Catalytic subunit of the Esc/E(z) complex, which methylates ’Lys-9’ and ’Lys-27’ of histone H3, leading to transcriptional repression of the affected target gene. While PcG proteins are generally required to maintain the transcriptionally repressive state of homeotic genes throughout development, this protein is specifically required during the first 6 hours of embryogenesis to establish the repressed state. The Esc/E(z) complex is necessary but not sufficient for the repression of homeotic target genes, suggesting that the recruitment o [...] (765 aa)

pho
Pleiohomeotic; Polycomb group (PcG) protein that binds to the 5’- CNGCCATNNNNG-3’ sequence found in the regulatory regions of many genes. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. Probably targets the Esc/E(z) complex to DNA. Necessary but not suffi [...] (520 aa)

z
Zeste; Involved in transvection phenomena (= synapsis-dependent gene expression), where the synaptic pairing of chromosomes carrying genes with which zeste interacts influences the expression of these genes. Zeste binds to DNA and stimulates transcription from a nearby promoter (605 aa)
