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

grhProtein grainyhead; Grainy head (grh) encodes the founding member of a highly conserved family of transcription factors essential for embryonic development. It is both a transcriptional activator and repressor, responsible for the proper expression of many genes primarily involved in epithelial cell fate, barrier formation, wound healing, tube morphogenesis and proliferation of larval neuroblasts; Belongs to the grh/CP2 family. Grainyhead subfamily. (1333 aa)    
Predicted Functional Partners:
abd-A
Homeobox protein abdominal-A; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Required for segmental identity of the second through eighth abdominal segments. Once a pattern of abd-A expression is turned on in a given parasegment, it remains on the more posterior parasegment, so that the complex pattern of expression is built up in the successive parasegments. Appears to repress expression of Ubx whenever they appear in the same cell, but abd-A is repressed [...]

Sce
E3 ubiquitin-protein ligase RING1; 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 [...]

dpn
Protein deadpan; Transcriptional repressor of genes that require a bHLH protein for their transcription. In the larval brain, required to maintain the self- renewal and identity of type II neuroblasts by regulating the expression of the transcriptional repressor erm together with other self-renewal transcriptional repressors such as klu and E(spl)mgamma- HLH. As part of its role in neuroblasts development, has been shown to be a direct target of the Notch signaling pathway, however might work also independently of N/Notch. In the developing larval and pupal brain, required for mushroom [...]

pdm2
POU domain protein 2, isoform B; DNA-binding regulatory protein implicated in early development. Involved in neuronal cell fate decision. May act as an octamer-dependent activator of transcription. Could also play an early role in specific ectodermal cells, and a subsequent role in the embryonic nervous system.
   
 
 0.645
hb
Protein hunchback; Gap class segmentation protein that controls development of head structures; Belongs to the hunchback C2H2-type zinc-finger protein family.
    
 
 0.633
Sp1
Sp1, isoform F; Sp1 (Sp1) encodes a member of the Sp-family of Cys2His2-type zinc finger transcription factors. It is involved in ventral thoracic appendage specification, leg growth and in the development of type-II neuroblasts.
    
 
 0.630
svp
Steroid receptor seven-up, isoform A; Receptor that is required in photoreceptors R1, R3, R4 and R6 during eye development; generation of the ganglion mother cell-2 (GMC- 2) fate in the nb7-3 lineage, coinciding with the transition in the expression of HB to KR in the neuroblasts (NBs). Belongs to the nuclear hormone receptor family. NR2 subfamily.

sqz
Zinc finger protein squeeze; Transcription factor involved in neuronal fate specification. First required in embryonic CNS development to define the number of cells that express apterous (ap) in the ap thoracic cluster of interneurons. Later on, it plays a central role in the combinatorial code of transcription factors that specifies the fate of the Tv neuron in the ap cluster by participating in the transcription regulation of FMRFa in Tv cells. Also required for projection neuron dendritic targeting.
    
 
 0.612
phol
Pleiohomeotic like (phol) encodes a zinc-finger protein that is 80% identical in the zinc-finger region to the product of pho. The product of phol plays a role in Polycomb group protein recruitment to Polycomb response elements, but it has additional roles, most likely as a transcriptional activator.
    
 
 0.607
Taf2
TBP-associated factor 2 (Taf2) encodes a protein that forms part of the multisubunit basal transcription factor TFIID. Together with the product of Taf1, it binds the Initiator and/or the DPE core promoter elements.
