Secretory proteins are proteins that are synthesized inside the cell and then secreted outside the cell to act. A secretory protein is any protein secreted by a cell, either endocrine or exocrine. Secretory proteins include many hormones, enzymes, toxins, and antimicrobial peptides. In eukaryotes, secretory proteins are proteins that are synthesized on the rough endoplasmic reticulum for "export". In prokaryotes, secretory proteins may be synthesized on ribosomes associated with the plasma membrane or exported post-translationally. Secretory proteins (e.g. cytokines, interleukins, growth factors and hormones) have multiple functions and are involved in cell signaling, regulation of cell proliferation, differentiation and apoptosis, development of the organism and other important life processes.
