Secretory pathway of proteins
WebProtein secretion has been for long believed to be exclusively taking place through the conventional ER/Golgi-dependent secretory pathway. However, in the last few decades, more and more studies pointed at several different routes for protein lacking a signal peptide to get secreted from cells. WebNot all glycosylation enzymes in the secretory pathway are type II membrane proteins. For example, the UDP-GlcNAc:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase (GlcNAc-phosphotransferase) …

Web26 Mar 2024 · They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. WebThere are two different secretory processes, constitutive secretion in which proteins are sorted into vesicles in the Golgi and move directly to the cell surface and fuse with the …
