Fig 4. Interaction of HIF-1α with ERβ2 in vitro.

A. His-tagged LBD-ERβ2 pull down with nickel agarose beads of in vitro translated HIF-1α compared to His-tagged LBD-ERα, His-tagged LBD-ERβ1, His-tagged LBD-ERβ2 and His-tagged ERβ2ΔCX TNT is lane with only coupled reticulocyte lysate. B. Expression of the biotin ligase BirA, HA-HIF-1α, and the N-terminal biotin consensus peptide fused receptor constructs B7TEV-ERα, B7TEV-ERβ1, B7TEV-ERβ2, B7TEV-ERβ5, and B7TEV-ERβΔCX in PC3 cells. Cell extracts were then subjected to pulldown with streptavidin magnetic beads and proteins separated by SDS-PAGE followed by detection with HIF-1α antibody.
