Seems to be involved in regulation of apoptosis. May be involved in detachment-mediated programmed cell death. May mediate apoptosis during neuronal development. May be involved in regulation of anti-apoptotic effects of IGF1. May be involved in translational regulation. Interacts with RPL14, EIF3S7 and PABPC4. Colocalizes with intracellular vesicles. Expression increases during embryonal development at embryonic days E11, E15 and E17. Induced by FGF in a hippocampal progenitor cell line. Induced by FGF and EGF in a CNS neuronal cell line.
