Predicted to enable several functions, including phosphoprotein binding activity; thyroid hormone receptor binding activity; and transcription coactivator activity. Predicted to be involved in nuclear-transcribed mRNA catabolic process; positive regulation of circadian rhythm; and regulation of RNA metabolic process. Predicted to act upstream of or within circadian rhythm. Predicted to be located in nuclear speck. Predicted to be part of mediator complex. Orthologous to human THRAP3 (thyroid hormone receptor associated protein 3). [provided by Alliance of Genome Resources, Apr 2022]
