The production of a secretory protein starts like any other protein. The mRNA is produced and transported to the cytosol where it interacts with a free cytosolic ribosome. The part that is produced first, the N-terminal, contains a signal sequence consisting of 6 to 12 amino acids with hydrophobic side chains.
Secretion in bacterial species means the transport or translocation of effector molecules. For example: proteins, enzymes or toxins (such as cholera toxin in pathogenic bacteria e.g. Vibrio cholerae) from across the interior (cytoplasm or cytosol) of a bacterial cell to its exterior. Secretion is a very important mechanism in bacterial ...
General secretory pathway (GSP) secretes proteins across bacterial cell membrane (CM) to bulge out lipopolysaccharide (LPS)-rich outer membrane (OM) above peptidoglycan (PDG) layer into pockets of inflated periplasm, called periplasmic organelles (PO) to pinch off OMVs containing outer membrane proteins (OMPs), secretory proteins (SP) and ...
Outbound proteins from the endoplasmic reticulum will bud off into transport vesicles that travel along the cell cortex to reach their specific destinations. [3] Since the ER is the site of protein synthesis, it would serve as the parent organelle, and the cis face of the golgi, where proteins and signals are received, would be the acceptor.

Secretomics is a type of proteomics which involves the analysis of the secretome—all the secreted proteins of a cell, tissue or organism. [1] Secreted proteins are involved in a variety of physiological processes, including cell signaling and matrix remodeling, but are also integral to invasion and metastasis of malignant cells. [2]
The translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. [1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from ...
The translocase of the outer membrane (TOM) sorts proteins via several mechanisms either directly to the outer membrane, the intermembrane space, or the translocase of the inner membrane (TIM). Then, generally, the TIM23 machinery mediates protein translocation into the matrix and the TIM22 machinery mediates insertion into the inner membrane. [9]
