Predicted to enable several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; metal ion binding activity; and signaling receptor binding activity. Involved in several processes, including negative regulation of viral genome replication; phosphatidylserine biosynthetic process; and response to interferon-alpha. Acts upstream of or within several processes, including cellular response to lipopolysaccharide; phosphatidylserine exposure on apoptotic cell surface; and positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage. Located in cytosol; nucleus; and plasma membrane. Is expressed in hindgut; midgut; renal calyx; and renal pelvis. Orthologous to human PLSCR1 (phospholipid scramblase 1).
