CUE domain found in activating signal cointegrator 1 complex subunit 2 (ASCC2) and similar proteins ASCC2, also called ASC-1 complex subunit p100 or Trip4 complex subunit p100, together with ASCC1 (also called p50) and ASCC3 (also called p300), form the activating signal cointegrator complex (ASCC). ASCC plays an essential role in activating protein 1 (AP-1), serum response factor (SRF), and nuclear factor kappaB (NF-kappaB) transactivation. It acts as a transcriptional coactivator of nuclear receptors and regulates the transrepression between nuclear receptors and either AP-1 or NF-kappaB in vivo. Members in this family all contain a CUE domain.
