Siah Proteins, HIF Prolyl Hydroxylases, and the Physiological Response to Hypoxia
نویسنده
چکیده
New evidence suggests that at least two members of the family of hypoxia-inducible factor (HIF) prolyl hydroxylases that regulate HIF stability in response to oxygen (O2) availability are also targeted for proteosome-dependent degradation by the E3 ubiquitin ligases Siah1a and Siah2. This preview examines cellular responses to O2 deprivation (hypoxia) and the complexity of the regulation of the HIF O2 sensing pathway in mammals.

Prolyl hydroxylases and therapeutics.
Prolyl hydroxylases are members of the iron- and 2-oxoglutarate-dependent dioxygenase enzyme family. Collagen prolyl hydroxylase is well known for its involvement in scurvy, in which ascorbate deficiency inhibits the enzyme and results in characteristic signs of the disease. Several distinct prolyl hydroxylases that hydroxylate (and thereby regulate) the hypoxia-inducible factor (HIF) transcrip...
متن کاملCatalytic properties of the asparaginyl hydroxylase (FIH) in the oxygen sensing pathway are distinct from those of its prolyl 4-hydroxylases.
The activity of hypoxia-inducible transcription factor HIF, an alphabeta heterodimer that has an essential role in adaptation to low oxygen availability, is regulated by two oxygen-dependent hydroxylation events. Hydroxylation of specific proline residues by HIF prolyl 4-hydroxylases targets the HIF-alpha subunit for proteasomal destruction, whereas hydroxylation of an asparagine in the C-termi...
متن کاملRecent Advances in Developing Inhibitors for Hypoxia-Inducible Factor Prolyl Hydroxylases and Their Therapeutic Implications.
Hypoxia-inducible factor (HIF) prolyl hydroxylases (PHDs) are members of the 2-oxoglutarate dependent non-heme iron dioxygenases. Due to their physiological roles in regulation of HIF-1α stability, many efforts have been focused on searching for selective PHD inhibitors to control HIF-1α levels for therapeutic applications. In this review, we first describe the structure of PHD2 as a molecular ...
متن کاملA dynamic model of the hypoxia-inducible factor 1α (HIF-1α) network.
Activation of the hypoxia-inducible factor (HIF) pathway is a critical step in the transcriptional response to hypoxia. Although many of the key proteins involved have been characterised, the dynamics of their interactions in generating this response remain unclear. In the present study, we have generated a comprehensive mathematical model of the HIF-1α pathway based on core validated component...
متن کاملTuning the Transcriptional Response to Hypoxia by Inhibiting Hypoxia-inducible Factor (HIF) Prolyl and Asparaginyl Hydroxylases*
The hypoxia-inducible factor (HIF) system orchestrates cellular responses to hypoxia in animals. HIF is an α/β-heterodimeric transcription factor that regulates the expression of hundreds of genes in a tissue context-dependent manner. The major hypoxia-sensing component of the HIF system involves oxygen-dependent catalysis by the HIF hydroxylases; in humans there are three HIF prolyl hydroxylas...
