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

dhs-163 beta-hydroxysteroid dehydrogenase dhs-16; 3 beta-hydroxysteroid dehydrogenase that converts 3 beta- hydroxysteroids to 3-ketosteroids, an essential step in the production of Delta(7)-dafachronic acid from cholesterol. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth. Required for longevity in the absence of the germline. Belongs to the short-chain dehydrogenases/reductases (SDR) family. (388 aa)    
Predicted Functional Partners:
daf-36
Cholesterol 7-desaturase; Catalyzes the production of 7-dehydrocholesterol (7-DHC) by the desaturation of the C7-C8 single bond of cholesterol. This reaction is the first step in the synthesis of the steroid hormone Delta(7)- dafachronic acid. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth.

hsd-1
3Beta_HSD domain-containing protein.

strm-1
Sterol 4-C-methyltransferase strm-1; Catalyzes the methyl transfer from S-adenosyl-methionine to the C-4 of cholesterol and other sterols. May irreversibly shunt sterols away from dafachronic acid production. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth.
   
  
 0.906
daf-9
Cytochrome P450 daf-9; Sterol hydroxylase that catalyzes the successive oxidization of the side chains of the 3-keto steroids 4-cholesten-3-one and lathosterone to form their carboxylic acid derivatives Delta(4)- dafachronic acid and Delta(7)-dafachronic acid respectively. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth. In a non-cell autonomous manner, negatively regulates body wall muscle arm extensions to motor neurons probably by preventing daf-12 isoform b activation. May be involved in ther [...]

daf-12
Nuclear hormone receptor family member daf-12; Nuclear receptor which binds directly to response elements in target gene promoters. Activity is modulated by binding of steroid hormone ligands that include dafachronic acids. Regulates expression of genes involved in postembryonic development and the dauer diapause, in response to environmental cues. Inhibits the expression of let-7 family members when bound to corepressor din-1s which is an isoform of din-1. Has a role in the immune response to bacterial infection, via regulation of let-7 miRNAs. Controls expression of genes that promot [...]

emb-8
NADPH--cytochrome P450 reductase; This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5; In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.

ncr-1
NPC intracellular cholesterol transporter 1 homolog 1; Involved in the uptake or utilization of cholesterol (By similarity). Ncr-1 and ncr-2 act redundantly to prevent dauer larva formation under favorable growth conditions, and are required for the normal functioning of ADF, ASI and ASG neurons. Belongs to the patched family.

ncr-2
NPC intracellular cholesterol transporter 1 homolog 2; Involved in the uptake or utilization of cholesterol (By similarity). Ncr-1 and ncr-2 act redundantly to prevent dauer larva formation under favorable growth conditions, and are required for the normal functioning of ADF, ASI and ASG neurons. Belongs to the patched family.

din-1
Daf-12-interacting protein 1; [Isoform d]: Probable transcriptional corepressor which modulates activity of the nuclear hormone receptor daf-12 to regulate the dauer diapause.
