Enables death receptor binding activity and protease binding activity. Involved in several processes, including cellular response to hormone stimulus; negative regulation of apoptotic process; and positive regulation of cell population proliferation. Located in membrane raft. Part of CD95 death-inducing signaling complex. Orthologous to human CFLAR (CASP8 and FADD like apoptosis regulator). [provided by Alliance of Genome Resources, Apr 2022]
