Predicted to enable several functions, including acetyltransferase activator activity; chromatin binding activity; and transcription coactivator activity. Involved in several processes, including negative regulation of DNA-binding transcription factor activity; negative regulation of autophagy; and regulation of apoptotic process. Predicted to be located in intercellular bridge; nucleoplasm; and perinuclear region of cytoplasm. Predicted to be part of protein-DNA complex. Predicted to be active in nucleus. Orthologous to human NUPR1 (nuclear protein 1, transcriptional regulator). [provided by Alliance of Genome Resources, Apr 2022]
