ICC/IF image of ab30782 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab30782 at 5μg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM.

Western blot - Anti-PHD3 antibody (AB30782)

This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab30782 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.

Supplementary information

The PHD3 protein also known as EGLN3 or Prolyl Hydroxylase Domain-Containing Protein 3 functions mechanically to regulate oxygen homeostasis in cells. It catalyzes the hydroxylation of proline residues on hypoxia-inducible transcription factors (HIFs). The molecular mass of PHD3 is approximately 27 kDa. PHD3 expresses in a variety of tissues notably in the heart brain and skeletal muscles. Its expression often occurs in response to hypoxic conditions reflecting its role in oxygen sensing and adaptation to change in oxygen levels.
Biological function summary

The PHD3 protein plays an essential role in regulating the degradation of HIFs preventing their accumulation under normoxic conditions. It is part of a larger complex which includes oxygen iron and 2-oxoglutarate facilitating its hydroxylase activity. Hydroxylation of HIFs by PHD3 marks them for degradation via the ubiquitin-proteasome pathway preventing HIFs from activating genes related to erythropoiesis angiogenesis and cellular metabolism adaptation to hypoxia. Through these actions PHD3 helps maintain cellular oxygen homeostasis and metabolic balance.

Pathways

PHD3 is integral to the HIF signaling pathway and the cellular response to hypoxia. Its interaction with HIF-1α and HIF-2α is important in this context dictating the stability and activity of these transcription factors under varying oxygen levels. PHD3 also associates with other prolyl hydroxylases such as PHD1 and PHD2 coordinating the regulation of HIFs collectively across different cell types and conditions. These interactions contribute to the modulation of gene expression in response to hypoxic stress.

Aberrant PHD3 activity links to cancer and ischemic diseases. In cancer altered PHD3 expression affects tumor growth and metastasis by disrupting normal oxygen sensing allowing cancer cells to adapt to low-oxygen environments. Moreover PHD3's interaction with proteins like HIF-1α and HIF-2α plays a role in the pathological angiogenesis seen in certain cancer types. In ischemic diseases improper regulation by PHD3 might impede normal tissue responses to reduced blood flow affecting recovery. Its specific modulation in diseases presents potential therapeutic targets for drug development.

Target data

Prolyl hydroxylase that mediates hydroxylation of proline residues in target proteins, such as PKM, TELO2, ATF4 and HIF1A (PubMed : 19584355, PubMed : 20978507, PubMed : 21483450, PubMed : 21575608, PubMed : 21620138, PubMed : 22797300). Target proteins are preferentially recognized via a LXXLAP motif. Cellular oxygen sensor that catalyzes, under normoxic conditions, the post-translational formation of 4-hydroxyproline in hypoxia-inducible factor (HIF) alpha proteins (PubMed : 11595184, PubMed : 12181324). Hydroxylates a specific proline found in each of the oxygen-dependent degradation (ODD) domains (N-terminal, NODD, and C-terminal, CODD) of HIF1A (PubMed : 11595184, PubMed : 12181324). Also hydroxylates HIF2A (PubMed : 11595184, PubMed : 12181324). Has a preference for the CODD site for both HIF1A and HIF2A (PubMed : 11595184, PubMed : 12181324). Hydroxylation on the NODD site by EGLN3 appears to require prior hydroxylation on the CODD site (PubMed : 11595184, PubMed : 12181324). Hydroxylated HIFs are then targeted for proteasomal degradation via the von Hippel-Lindau ubiquitination complex (PubMed : 11595184, PubMed : 12181324). Under hypoxic conditions, the hydroxylation reaction is attenuated allowing HIFs to escape degradation resulting in their translocation to the nucleus, heterodimerization with HIF1B, and increased expression of hypoxy-inducible genes (PubMed : 11595184, PubMed : 12181324). ELGN3 is the most important isozyme in limiting physiological activation of HIFs (particularly HIF2A) in hypoxia. Also hydroxylates PKM in hypoxia, limiting glycolysis (PubMed : 21483450, PubMed : 21620138). Under normoxia, hydroxylates and regulates the stability of ADRB2 (PubMed : 19584355). Regulator of cardiomyocyte and neuronal apoptosis. In cardiomyocytes, inhibits the anti-apoptotic effect of BCL2 by disrupting the BAX-BCL2 complex (PubMed : 20849813). In neurons, has a NGF-induced proapoptotic effect, probably through regulating CASP3 activity (PubMed : 16098468). Also essential for hypoxic regulation of neutrophilic inflammation (PubMed : 21317538). Plays a crucial role in DNA damage response (DDR) by hydroxylating TELO2, promoting its interaction with ATR which is required for activation of the ATR/CHK1/p53 pathway (PubMed : 22797300). Also mediates hydroxylation of ATF4, leading to decreased protein stability of ATF4 (Probable).
