Predicted to enable diamine N-acetyltransferase activity; identical protein binding activity; and spermidine binding activity. Acts upstream of or within regulation of cell population proliferation. Predicted to be located in cytoplasm. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human SAT1 (spermidine/spermine N1-acetyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
