Abstract
To sustain life mammals have an absolute and continual requirement for oxygen, which is necessary to produce energy for normal cell survival and growth. Hence, maintaining oxygen homeostasis is a critical requirement and mammals have evolved a wide range of cellular and physiological responses to adapt to changes in oxygen availability. In the past few years it has become evident that the transcriptional protein complex hypoxia‐inducible factor (HIF) is a key regulator of these processes. In this review we will focus on the way oxygen availability regulates HIF proteins and in particular we will discuss the way oxygen‐dependent hydroxylation of specific amino acid residues has been demonstrated to regulate HIF function at the level of both protein stability and transcriptional potency.Keywords
