Predicted to enable cAMP response element binding protein binding activity. Predicted to be involved in macrophage activation; positive regulation of CREB transcription factor activity; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within energy homeostasis; negative regulation of adenylate cyclase-activating adrenergic receptor signaling pathway; and negative regulation of lipid catabolic process. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in cytoplasm and nucleus. Orthologous to human CRTC3 (CREB regulated transcription coactivator 3).
