    basic FUNCTION
  • may play a positive role in AHR-mediated (aromatic hydrocarbon receptor) signaling
  • acting as a cellular negative regulator of the hepatitis B virus (HBV) X protein
  • inhibits glucocorticoid receptor by reducing its responsiveness to hormone in transcriptional activation (requires its interaction with Hsp90 through the TPR motif)(Laenger 2009)
  • reduce ubiquitination of the receptor and to regulate its subcellular distribution (Laenger 2009)
  • involved in the development of pituitary tumors, especially involving the somatomammotroph lineage (Cazabat 2009)
  • expression of AIP in hepatocytes is essential to maintain high levels of functional cytosolic AHR protein in the mammalian liver, and expression of the AIP protein is essential for dioxin-induced hepatotoxicity
  • has a major role in the pathogenesis of familial isolated pituitary adenoma, but is rarely involved in parathyroid adenomas
  • AIP is a novel inhibitor of IRF7 and a negative regulator of innate antiviral signaling
  • AIP mutations affect the AIP protein level and alter AHR transcriptional activity in a gene- and tissue-dependent manner
  • encodes for a co-chaperone protein endowed with tumor suppressor properties in somatotroph cells
    signaling signal transduction
    a component
    small molecule
  • HSP90-AHR complex
  • AIP-TOMM20 recognition contributes to cell survival in development and cancer by mediating the mitochondrial import of BIRC5
  • negative regulator of the hepatitis B virus X-associated protein
  • AIP exerts a negative effect on ESR1 transcriptional activity and may thus prevent ESR1-dependent events
  • interactions with the aryl hydrocarbon receptor (AHR, also known as dioxin receptor), two HSP90 proteins, PDE4A, PPAR, and survivin
  • AIP augments CARMA1-BCL10-MALT1 complex formation to facilitate NFKB1 signaling upon T cell activation
  • AIP (aryl hydrocarbon receptor interacting protein) is a new binding partner of IRF7
  • interaction with over-expressed AIP does not seem to affect PDE2A function, but the reported effect on PDE4A is, in contrast, reduced enzymatic activity
