MADD — MAP kinase activating death domain
MADD belongs to a gene co-expression module in 2 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
Guanyl-nucleotide exchange factor that regulates small GTPases of the Rab family. Converts GDP-bound inactive form of RAB27A and RAB27B to the GTP-bound active forms. Converts GDP-bound inactive form of RAB3A, RAB3C and RAB3D to the GTP-bound active forms, GTPases involved in synaptic vesicle exocytosis and vesicle secretion (By similarity). Plays a role in synaptic vesicle formation and in vesicle trafficking at the neuromuscular junction (By similarity). Involved in up-regulating a post-docking step of synaptic exocytosis in central synapses (By similarity). Probably by binding to the motor proteins KIF1B and KIF1A, mediates motor-dependent transport of GTP-RAB3A- positive vesicles to the presynaptic nerve terminals (By similarity). Plays a role in TNFA-mediated activation of the MAPK pathway, including ERK1/2. May link TNFRSF1A with MAP kinase activation. May be involved in the regulation of TNFA-induced apoptosis.
