Probably participates in neurogenesis. Could play a role in regulating gene activity in the proliferative and/or differentiative pathways induced by NGF. Interacts with PSIP1/LEDGF. Presents a NGF-dependent pattern of intracellular localization. With increasing amounts of NGF and besides being expressed in the cytoplasm, it is also localized in the plasma membrane (inner side) at the onset of NGF-induced differentiation, from where it disappears to reappear in the nuclei of differentiated cells. Expressed at high levels in the embryonic brain in the period related to neuroblast proliferation and differentiation. Activated at the onset of neuronal differentiation. By nerve growth factor. Belongs to the IFRD family.
