Involved in neural development, regulating the establishment of proper connectivity within the nervous system. May function as a cellular signal transducer (By similarity).
Plays a role in the regulation of neuroplasticity in the limbic system. Mediates a rapid reorganization of actin- and tubulin-based cytoskeleton elements with an increase in dendritic arborization and spine density formation of neurons in the hippocampus and amygdala. Induces BDNF transcription inhibition in neurons. Activates the mitogen-activated protein (MAP) kinase 2 (MEK2) and extracellular signal-regulated kinase (ERK) cascade. Acts also as a bioactive neuroprotective peptide on limbic neurons of the brain and regulates stress-induced behavior: attenuates alkalosis-associated necrotic cell death and the effects of corticotropin-releasing factor (CRF) on c-fos/FOS induction and on the reinstatement of cocaine seeking (By similarity).
Induces gene transcription activation.

Colocalizes with the dystroglycan complex at the cell membrane in hippocampal cells. Binds hippocampal cell membranes and is incorporated in the cytoplasm by endocytosis in a caveoli-dependent manner. Upon cell internalization is transported arround and in the nucleus (By similarity).
Expressed in fetal brain.
