Abstract:
Annexins are calcium- and phospholipid-binding proteins that have been proposed to have multiple roles in membrane traffic. Historically, this has been based on the in vitro properties of annexins and their localization to specific membrane compartments. However, recent functional evidence supports a role for annexins in specific membrane traffic steps, although the requirement for annexins may be highly dependent on the cellular context. Here we review the roles of annexins in traffic within the endocytic pathway, focusing on clathrin-dependent internalization from the plasma membrane, multivesicular endosome/body (MVB) biogenesis and MVB-lysosome fusion.

Endocytosis
Endocytosis always begins with the plasma membrane enclosing an incoming molecule to form a transport vesicle which, in some cases, can be coated with a protein called ‘clathrin.' Endocytosed material is either sorted through...
Vesicular Trasport: Endocytosis, Transcytosis and Exocytosis
Endocytosis is a cellular mechanism that involves the inward folding of the cell membrane to create vesicles that capture and transport large drug molecules. This process comprises two distinct methods: pinocytosis (often referred to as "cell drinking") and phagocytosis (often referred to as "cell eating"). Pinocytosis is...
Introduction to Membrane Traffic
The transport of soluble and membrane proteins is mediated by transport vesicles that collect cargo from one cellular compartment and deliver it to another by fusing with the target organelle membrane. The Rab...
