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.

SREBPSterol regulatory element binding protein (SREBP) encodes a membrane protein that functions as a master-regulator of lipogenesis. It activates transcription of lipogenic genes upon reduction of lipid or cholesterol levels. (1113 aa)    
Predicted Functional Partners:
S2P
Metalloendopeptidase activity. It is involved in the biological process described with: positive regulation of transcription from RNA polymerase II promoter in response to endoplasmic reticulum stress; sterol regulatory element binding protein cleavage; membrane protein intracellular domain proteolysis; positive regulation of DNA-binding transcription factor activity.
   
 0.985
Hmgcr
3-hydroxy-3-methylglutaryl-coenzyme A reductase; Synthesis of mevalonate for the production of non-sterol isoprenoids, which are essential for growth differentiation. Provides spatial information during embryogenesis to guide migrating primordial germ cells (the pole cells) from the ectoderm to the mesoderm. Also required for association of the pole cells with the gonadal mesoderm. Belongs to the HMG-CoA reductase family.

MED15
Mediator of RNA polymerase II transcription subunit 15; Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene- specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors (By similarity). Required [...]

SCAP
SREBP cleavage activating protein; Sterol binding. It is involved in the biological process described with: sterol regulatory element binding protein cleavage; protein processing; SREBP signaling pathway.
   
 0.973
Npc1a
Niemann-Pick type C-1a (Npc1a) encodes a cholesterol trafficking protein that contributes to sterol and ecdysone metabolism. It is involved in sperm individualization.
   
 
 0.955
FASN1
Fatty acid synthase 1 (FASN1) encodes a fatty acid synthase involved in glycogen metabolism and triglyceride biosynthesis.
   
 
 0.942
S1P
Serine-type endopeptidase activity. It is involved in the biological process described with: sterol regulatory element binding protein cleavage; proteolysis.
    
 0.922
Fs(2)Ket
Importin subunit beta; Required for nuclear protein import and mediates docking of import substrate to distinct nucleoporins. In Drosophila, may not function as a snRNP import receptor as it does not interact with components of the snRNP complex such as snRNP U1, U2, U4/U6 and Snup.
   
 0.922
Hnf4
Transcription factor HNF-4 homolog; Hepatocyte nuclear factor 4 (Hnf4) encodes a protein that regulates lipid mobilization and fatty acid beta-oxidation during larval stages. Its expression increases greatly at the onset of adulthood when it promotes glucose-stimulated ILP secretion from the insulin-producing cells, maintains glucose homeostasis, and supports mitochondrial function; Belongs to the nuclear hormone receptor family. NR2 subfamily.
   
 
 0.896
Npc1b
NPC intracellular cholesterol transporter 1 homolog 1b; Important for cholesterol absorption at the midgut epithelium. Acts only in the early steps of sterol absorption, prior to Npc1a-dependent intracellular sterol trafficking. Belongs to the patched family.
