Involved in neural development, regulating the establishment of proper connectivity within the nervous system. May function as a cellular signal transducer (By similarity). . [Teneurin C-terminal-associated peptide]: 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. Also acts 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). . [Ten-1 intracellular domain]: Induces gene transcription activation. . This is the function of Ensembl gene identifier ENSG00000009694 (TENM1, teneurin transmembrane protein 1).
