Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; cAMP response element binding activity; and identical protein binding activity. Predicted to be involved in positive regulation of transcription, DNA-templated; regulation of transcription by RNA polymerase II; and white fat cell differentiation. Predicted to act upstream of or within adipose tissue development; fat cell differentiation; and positive regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Orthologous to human CREB5 (cAMP responsive element binding protein 5). [provided by Alliance of Genome Resources, Apr 2022]
