Interaction of TG2 with HIF-1β.

<p><b>A</b>, Representative immunoblots showing the coimmunoprecipitation of TG2 with HIF-1β. Top panel: HIF-1β was immunoprecipitated from the cell lysates of stable striatal cell lines and blotted for TG2. Bottom panel: The top blot was stripped and re-probed for HIF-1β. Wild type TG2, and the mutants TG2-C277S (C277S), TG2-R580A (R580A) immunoprecipitated with HIF-1β. <b>B</b>, 5% of the total amount of cell lysate used for immunoprecipitation was blotted for TG2 and HIF-1β.
