Description: Several neuropeptide families are involved in the aetiology of mood disorders. However, the corticotropin releasing factor (CRF) peptide family plays a pivotal role in many of these disorders. The teneurin C-terminal associated peptides (TCAP) are a recently discovered peptide family, which is structurally related to CRF. Free TCAP was identified in neuronal cells using HPLC and MS approaches initially and subsequently by SDS-PAGE purification and western blot identification by TCAP1-specific antisera. The immunohistochemical detection of TCAP-1 like expression in the rat forebrain regions implicated its functions in regulating stress and anxiety. The physiological activity of TCAP was assessed by the in vitro and in vivo  activities of synthetic mouse TCAP-1 and rainbow trout TCAP-3. TCAP signals, in part, through cAMP pathway in a dose-dependent manner on a receptor that is unlikely the CRF-R1. These studies show that TCAP is a novel neuropeptide displaying its own physiological functions distinct from CRF.
