ER81 (ETV1) co-immunoprecipitates with the transcriptional coactivators CBP and p300, and co-localizes with p300 in nuclear speckles; the ETS DNA-binding domain (aa 249–429) mediates binding to CBP/p300. Two regions within CBP (aa 451–721 and 1891–2175) bind ER81. An ER81-associated kinase phosphorylates ER81 on Ser191 and Ser216, and p300 overexpression enhances this kinase activity. |
