[Encoded by MADD Gene, MADD Protein Isoforms A-G are expressed in adult testis, ovary, brain, heart, and fetal brain and kidney. The 1588-amino acid 176.6-kD isoform D is full-length. Most variants involve 2-4 stretches of 18-43 amino acids in the central region. Isoforms F and G have a different C-terminus. Containing a C-terminal death domain, RGD motif, and a leucine zipper-like motif, SER- and LEU-rich membrane-bound MADD adaptor protein interacts with TNFR1 death domain to propagate apoptotic signaling. MADD can activate ERK2 and JNK1 MAP kinases and induce phosphorylation of Phospholipase A2. MADD appears to link TNFR1 with MAP kinase activation and arachidonic acid release.
