Hypoxia-inducible factor (HIF), a transcriptional activator involved in control of cell cycle in response to hypoxic conditions, is an important target for FIH regulation. FIH functions as an oxygen sensor that regulates HIF function by hydroxylating at Asn803 in the carboxy-terminal transactivation domain (CAD) of HIF. During normoxia, FIH uses cellular oxygen to hydroxylate HIF-1 and prevent interaction of HIF-1 with transcriptional coactivators, including the CBP\/p300-interacting transactivator. Under hypoxic conditions, FIH remains inactive and does not inhibit HIF, allowing the activator to regulate transcription of genes in response to low oxygen conditions. FIH activity is regulated in through interaction with proteins, including Siah-1, which targets FIH for proteasomal degradation. The Cut-like homeodomain protein CDP can bind the FIH promoter region to regulate FIH expression at the transcriptional level. Phosphorylation of HIF at Thr796 also can prevent FIH hydroxylation on Asn803. Potential FIH substrates also include proteins with ankyrin repeat domains, such as Iκ-B, Notch, and ASB4.\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: This antibody is purified through a protein G column.\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.

Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a AF488-conjugated secondary antibody (green) in PBS at room temperature in the dark. Phalloidin - AF555 was used to stain the cytoplasm (red). DAPI was used to stain the cell nuclei (blue).\u003c\/p\u003e\n\n\u003cp\u003eAlternative Name: FIH1; Hypoxia-inducible factor 1-alpha inhibitor; Factor inhibiting HIF-1; FIH-1; Hypoxia-inducible factor asparagine hydroxylase\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: KLH-conjugated synthetic peptide encompassing a sequence within the center region of human FIH-1.
