Function:Involved in the apoptotic response after nerve growth factor (NGF) binding in neuronal cells. Binds p75NTR and antagonizes its association with TrkA , inhibits cell cycle progression , and facilitates p75NTR-mediated apoptosis. May act as a regulator of the function of DLX family members. May regulate p53 transcriptional activity and inhibit cell proliferation. Enhances p53 phosphorylation and accumulation. ,similarity:Contains 1 MAGE domain. ,subcellular location:Expression shifts from the cytoplasm to the plasma membrane upon stimulation with NGF. ,subunit:Interacts with DLX5 , DLX7 and MSX2 and forms homomultimers. Interacts with UNC5A (By similarity) . Interacts with the p75 neurotrophin receptor. ,tissue specificity:Expressed in bone marrow stromal cells from both multiple myeloma patients and healthy donors. Seems to be ubiquitously expressed. ,
