STRING protein interaction network
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
Your Input:
Gene Fusion
FEVProtein FEV; Functions as a transcriptional regulator. According to PubMed:12761502, it functions as a transcriptional repressor. Functions in the differentiation and the maintenance of the central serotonergic neurons. May play a role in cell growth; ETS transcription factor family (238 aa)    
Predicted Functional Partners:
Tryptophan hydroxylase 2
Sodium-dependent serotonin transporter; Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner; Belongs to the sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family. SLC6A4 subfamily
Protein mab-21-like 2; Required for several aspects of embryonic development including normal development of the eye; Belongs to the mab-21 family
5-hydroxytryptamine receptor 1A; G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for various drugs and psychoactive substances. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Signaling inhibits adenylate cyclase activity and activates a phosphatidylinositol-calcium second [...]
Neurogenin-3; Acts as a transcriptional regulator. Together with NKX2- 2, initiates transcriptional activation of NEUROD1. Involved in neurogenesis. Also required for the specification of a common precursor of the 4 pancreatic endocrine cell types (By similarity); Basic helix-loop-helix proteins
LIM homeobox transcription factor 1-beta; Essential for the specification of dorsal limb fate at both the zeugopodal and autopodal levels; LIM class homeoboxes
Putative nucleotidyltransferase MAB21L1; Putative nucleotidyltransferase required for several aspects of embryonic development including normal development of the eye (By similarity). It is unclear whether it displays nucleotidyltransferase activity in vivo. Binds single-stranded RNA (ssRNA)
Homeobox protein Nkx-2.2; Acts as a transcriptional activator. Required for the maintenance of NEUROD1 expression in the horomone-producing endocrine cells of the pancreas. May be involved in specifying diencephalic neuromeric boundaries, and in controlling the expression of genes that play a role in axonal guidance. Associates with chromatin at the NEUROD1 promoter region. Binds to a subset of consensus elements within the NEUROD1 promoter (By similarity); Belongs to the NK-2 homeobox family
Tryptophan hydroxylase 1
Beta-crystallin A2; Crystallins are the dominant structural components of the vertebrate eye lens
