Predicted to enable leucine zipper domain binding activity; protein kinase binding activity; and tau protein binding activity. Acts upstream of or within several processes, including negative regulation of amyloid precursor protein biosynthetic process; negative regulation of apoptotic signaling pathway; and regulation of mitotic cell cycle. Located in cytoplasm and nucleolus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; early conceptus; genitourinary system; liver; and nervous system. Orthologous to human AATF (apoptosis antagonizing transcription factor). [provided by Alliance of Genome Resources, Apr 2022]
