Acidic leucine-rich nuclear phosphoprotein 32 family member B (ANP32B) also known as "acidic protein rich in leucines" (APRIL) is a protein that in humans is encoded by the ANP32Bgene.[5][6][7]
APRIL is also the acronym used for an entirely different protein, TNFSF13, a member of the tumor necrosis factor superfamily whose alternative name, A PRoliferation Inducing Ligand, shares the same acronym as that for ANP32B
