PHD2 (Prolyl Hydroxylase Domain-containing protein 2) belongs to the Prolyl-4-hydroxylase domain (PHD) family of proteins and is encoded by the Egl-9 Family Hypoxia Inducible Factor 1 (EGLN1) gene (1). Human EGLN1/PHD2 is a ubiquitously expressed enzyme that is 426 amino acids (aa) long with a theoretical molecular weight of ~46 kDa. Structurally PHD2 contains a nuclear export signal (NES, aa 6-20), an N-terminal MYND zinc finger domain (aa 21-58), and a C-terminal catalytic domain (aa 291-392) (2, 3). Functionally, PHD2 serves as an oxygen sensor and is responsible for post-translational modification of Hypoxia-inducible factor alpha (HIF-1alpha), a component of a transcriptional complex involved in oxygen homeostasis (1-3). During normoxia, PHD2 is responsible for oxygen-dependent hydroxylation of HIF-1alpha proline residue 402, 564, or both (3). The hydroxylation event promotes the binding of von Hippel-Lindau protein (VHL) and targets HIF1-alpha for ubiquitination and degradation (4, 5).

EGLN1/PHD2 has been implicated in several critical processes including erythropoiesis, angiogenesis, and metabolism as well as various pathologies such as cancer (2, 5, 6). Studies in mice have found that somatic deletion of PHD2 resulted in higher vascular endothelial growth factor A (VEGF-A) levels, increased blood vessel formation, and more erythropoietin (EPO), leading to severe polycythemia or erythrocytosis (high red blood cell (RBC) volume) (6). Another study revealed that specific point mutations in EGLN1/PHD2 led to elevated EPO and RBC mass associated with hemorrhages and strokes (6). Accordingly, given the known role of PHD2 in inhibition of EPO production, PHD2 inhibitors are being studied as a potential therapeutic for anemia (6). Additionally, dysregulation in EGLN1, and specifically the PHD2-VHL-HIF-1alpha pathway, has been associated with the development of pheochromocytomas (PCC) and sympathetic paragangliomas (PGL), which are rare neuroendocrine tumors (2). Besides pathological features, EGLN1/PHD2 may also be important for high altitude adaptation as two coding sequence variants in PHD2 are prevalent in the Tibetan population but is very rare in people at lower altitudes (2).

Alternate names for EGLN1/PHD2 include HIF Prolyl Hydroxylase 2, PH2, Prolyl hydroxylase domain containing protein 2, HIF2PH2, HIF-Prolyl hydroxylase 2, egl nine homolog 1, and C1orf12.
