Facts about Hypoxia-inducible factor 1-alpha.
Heterodimerizes with ARNT; heterodimer binds to core DNA sequence 5'-TACGTG-3' inside the hypoxia response element (HRE) of target gene promoters (By similarity). Activation requires recruitment of transcriptional coactivators like CREBBP and EP300.

Expressed in most tissues with highest levels in kidney and heart. Overexpressed in the majority of common human cancers and their metastases, due to the presence of intratumoral hypoxia and as a result of mutations in genes encoding oncoproteins and tumor suppressors. A higher level expression seen in pituitary tumors as compared to the pituitary gland.
