Protein secretion mechanisms - Microbiology - Utrecht University

A secretory protein is any protein, whether it be endocrine or exocrine, which is secreted by a cell. Secretory proteins include many hormones, enzymes, toxins, and antimicrobial peptides. Secretory proteins are synthesized in the endoplasmic reticulum. Web15 jan. 2011 · Introduction. The secretory pathway is where synthesis and delivery of soluble proteins occur that have been secreted into the extracellular space – a process called secretion ( Box 1 ). Most of the cellular transmembrane proteins (except those of the mitochondria) use this pathway to reach their final destination. WebProteins made in the rough endoplasmic reticulum as destined to either be a part of a membrane, or to be secreted from the cell membrane out of the cell.
