Description

EGLN2, also known as PHD1 (prolyl hydroxylase domain-containing protein 1), serves as a critical oxygen sensor in cellular physiology. As one of three prolyl hydroxylases that regulate hypoxia-inducible factor (HIF) stability, EGLN2 hydroxylates specific proline residues on HIF-α subunits under normoxic conditions, targeting them for proteasomal degradation. This regulatory mechanism positions EGLN2 at the center of cellular oxygen sensing pathways, making it a compelling target for researchers investigating hypoxia responses, metabolic adaptation, and tumor microenvironment biology.

This recombinant monoclonal antibody, generated against a synthetic peptide from human EGLN2, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant production yields a sequence-defined antibody from a single clone, researchers can expect uniform performance across experiments and between lot numbers, eliminating a common source of variability in long-term studies.

Validation across multiple platforms demonstrates this antibody's experimental flexibility. Western blot analysis confirms specific detection in human cell lines including HL-60, MCF-7, and HeLa, with cross-species reactivity demonstrated in mouse brain tissue. The observed band at approximately 55 kDa runs higher than the predicted 44 kDa molecular weight, likely reflecting post-translational modifications such as glycosylation that are characteristic of the native protein. Immunofluorescence staining in A549 cells reveals clear cytoplasmic localization, while flow cytometry analysis in MCF-7 cells shows distinct positive population shifts compared to isotype controls.

This antibody supports investigations into oxygen-sensing mechanisms, HIF pathway regulation, and the metabolic reprogramming that characterizes cancer progression and ischemic disease models.

Target Background

Function

Prolyl hydroxylase that mediates hydroxylation of proline residues in target proteins, such as ATF4, IKBKB, CEP192 and HIF1A. 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. Hydroxylates a specific proline found in each of the oxygen-dependent degradation (ODD) domains (N-terminal, NODD, and C-terminal, CODD) of HIF1A. Also hydroxylates HIF2A. Has a preference for the CODD site for both HIF1A and HIF2A. Hydroxylated HIFs are then targeted for proteasomal degradation via the von Hippel-Lindau ubiquitination complex. 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. EGLN2 is involved in regulating hypoxia tolerance and apoptosis in cardiac and skeletal muscle. Also regulates susceptibility to normoxic oxidative neuronal death. Links oxygen sensing to cell cycle and primary cilia formation by hydroxylating the critical centrosome component CEP192 which promotes its ubiquitination and subsequent proteasomal degradation. Hydroxylates IKBKB, mediating NF-kappa-B activation in hypoxic conditions. Also mediates hydroxylation of ATF4, leading to decreased protein stability of ATF4.
