Apoptosis regulatory protein Siva is a protein that in humans is encoded by the SIVA1 gene.This gene encodes a protein with an important role in the apoptotic (programmed cell death) pathway induced by the CD27 antigen a member of the tumor necrosis factor receptor (TFNR) superfamily. The CD27 antigen cytoplasmic tail binds to the N-terminus of this protein. Two alternatively spliced transcript variants encoding distinct proteins have been described.
