STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

su(Hw)Protein suppressor of hairy wing; Component of the gypsy chromatin insulator complex which is required for the function of the gypsy chromatin insulator and other endogenous chromatin insulators. Chromatin insulators are regulatory elements which establish independent domains of transcriptional activity within eukaryotic genomes. Insulators have two defining properties; they can block the communication between an enhancer and a promoter when placed between them and can also buffer transgenes from position effect variegation (PEV). Insulators are proposed to structure the chromatin fibe [...] (941 aa)    
Predicted Functional Partners:
Cp190
Centrosome-associated zinc finger protein CP190; Component of the gypsy chromatin insulator complex which is required for the function of the gypsy chromatin insulator and other endogenous chromatin insulators. Chromatin insulators are regulatory elements which establish independent domains of transcriptional activity within eukaryotic genomes. Insulators have two defining properties; they can block the communication between an enhancer and a promoter when placed between them and can also buffer transgenes from position effect variegation (PEV). Insulators are proposed to structure the [...]

mod(mdg4)
Modifier of mdg4; Component of the gypsy chromatin insulator complex which is required for the function of the gypsy chromatin insulator and other endogenous chromatin insulators. Chromatin insulators are regulatory elements which establish independent domains of transcriptional activity within eukaryotic genomes. Insulators have two defining properties; they can block the communication between an enhancer and a promoter when placed between them and can also buffer transgenes from position effect variegation (PEV). Insulators are proposed to structure the chromatin fiber into independe [...]

BEAF-32
Boundary element-associated factor of 32kD (BEAF-32) encodes a DNA-binding protein with binding sites near transcription start sites. Its roles include chromatin domain insulator function, gene regulation and genome organization.

e(y)2
Enhancer of yellow 2 transcription factor; Involved in mRNA export coupled transcription activation by association with both the AMEX and the SAGA complexes. The SAGA complex is a multiprotein complex that activates transcription by remodeling chromatin and mediating histone acetylation and deubiquitination. Within the SAGA complex, participates in a subcomplex that specifically deubiquitinates histone H2B. The SAGA complex is recruited to specific gene promoters by activators, where it is required for transcription. Required for nuclear receptor-mediated transactivation. Involved in t [...]

Topors
E3 ubiquitin-protein ligase Topors; Functions as a ubiquitin-protein E3 ligase. Negatively regulates the transcriptional repressor h/hairy by promoting its ubiquitination and subsequent degradation. Also directs the nuclear organization of the gypsy chromatin insulator. Chromatin insulators are regulatory elements which establish independent domains of transcriptional activity within eukaryotic genomes. Insulators have two defining properties; they can block the communication between an enhancer and a promoter when placed between them, and can also buffer transgenes from position effec [...]

y
Yellow (y) is the founding gene of the Yellow family. Lack of y function results in an abnormal male courtship behavior and a characteristic yellow color of the adult cuticle and larval mouthparts; Belongs to the major royal jelly protein family.

Ibf1
Insulator binding factor 1, isoform A; Sequence-specific DNA binding; protein heterodimerization activity; chromatin insulator sequence binding; protein binding. It is involved in the biological process described with: positive regulation of chromatin silencing.

HIPP1
HP1 and insulator partner protein 1 (HIPP1) encodes a chromatin-associated protein, displaying strong protein-protein interaction with the product of Su(var)205. It is localized to pericentric heterochromatin, and potentially has a separate role bound to insulators along with the products of su(Hw), mod(mdg4) and Cp190.

Trl
Transcription factor GAGA; Transcriptional activator that functions by regulating chromatin structure. Overcomes the repressive effects of chromatin by promoting the open chromatin conformation in promoter gene regions, thereby allowing access to other transcription factors. Binds to DNA Polycomb response elements (PREs) at the bithorax complex and to the proximal region of the engrailed promoter, and positively regulates transcription of many genes including homeotic ones. Binds to the DNA sequence (GA)n, with optimal binding to the pentamer 5'-GAGAG-3'. Binds DNA as an oligomer. May [...]
