Predicted to enable transcription cis-regulatory region binding activity and transcription coactivator activity. Predicted to be involved in adipose tissue development and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; cellular response to leukemia inhibitory factor; and face morphogenesis. Orthologous to human ARID5B (AT-rich interaction domain 5B). [provided by Alliance of Genome Resources, Apr 2022]
