Hypoxia induced factors (HIFs) are transcription factors responding to decreased oxigen levels in the cellular environment. Hypoxia induced factor 1 alpha (HIF1A) is a protein constantly expressed in mammalian cells. Under normoxic conditions HIF1A is hydroxylated and is marked by the E3 ubiquitin ligase which leads to the degradation by the proteasome. However, in hypoxic conditions HIF1A is stabilized and can heterodimerize with HIF1B. Also HIF1A transcription is often significantly upregulated under hypoxic conditions. Under hypoxic conditions HIF1 can then bind to hypoxia response elements (HREs) (BBa_K2295003) in the nucleus and lead to the expression of the gene of interest (Ziello et al., 2007).
