Predicted to enable enzyme binding activity; estrogen receptor binding activity; and transcription coactivator activity. Predicted to be involved in several processes, including intracellular estrogen receptor signaling pathway; regulation of cellular macromolecule biosynthetic process; and ribosome-associated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within toxin transport. Predicted to be located in cytoplasm; neuromuscular junction; and nuclear body. Predicted to be part of activating signal cointegrator 1 complex. Predicted to be active in nucleus. Predicted to colocalize with centrosome. Orthologous to human TRIP4 (thyroid hormone receptor interactor 4). [provided by Alliance of Genome Resources, Apr 2022]
