ProSAAS is a newly discovered protein with a neuroendocrine distribution generally similar to that of prohormone convertase 1 (PC1), a peptide processing endopeptidase. ProSAAS mRNA is broadly distributed among neurons in brain and other neuroendocrine tissues (pituitary, adrenal, pancreas). Overexpression of ProSAAS in the AtT-20 cells substantially reduces the rate of processing of POMC(endogenous prohormone proopiomelanocortin) [1]. In wild type mouse brain and pituitary, the majority of ProSAAS is processed into smaller peptides including Little SAAS, PEN and big LEN.[2] A few obesity related propeptides have been processed by PC1 and obesity has been observed to be associated with mutations in the human PC1 gene[3].Does proSAAS- derived peptides play a role in the development of obesity?
