CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus

basic FUNCTION	asparaginyl hydroxylase enzyme regulating the transcriptional activity of hypoxia-inducible factor
	regulates not only HIF activity, but also the NOTCH signaling output and, in addition, plays a role in how NOTCH signaling modulates the hypoxic response
	role as a modulator of the growth of human tumor cells
	its activity is essential for tumor growth through the suppression of the TP53-CDKN1A axis, the major barrier that prevents cancer progression

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

HIF1AN forms a complex with APBA3, and these two factors co-localize within the perinuclear region

INTERACTION

DNA

RNA

small molecule

protein	NOTCH is likely to become efficiently hydroxylated by HIF1AN even under relatively severe hypoxic conditions, where HIF1A hydroxylation would be reduced
	inhibits the activity of HIF1A by preventing HIF1alpha binding to EP300 via modification of the Asn(803) residue
	functions as a cytosol retention factor of BAX, blocking BAXtranslocation from cytosol to mitochondria in response to apoptotic stimuli
	is an UBE3A-interacting protein
	KDM8 participates in roles independent of histone demethylation and may function as a protein hydroxylase given its structural homology with HIF1AN and JMJD6
