part_of protein secretory pathway protein exocytosis pathway PW:0000636 The protein exocytosis pathway involves trafficking of protein-containing vesicles to their final destination. It consists of several steps: budding, transport mediated by microtubule and actin associated molecular motors, tethering/docking and fusion with target membrane. Members of the Arf and Rab family of Ras superfamily are involved in the control of exit from Golgi and exocytic route, respectively. These are two main types of protein exocytosis which also represented in the more general exocytosis thereby material is delivered outside the cell. pathway
