klatriinivälitteisen

Klatriinivälitteinen refers to a process or mechanism mediated by clathrin. Clathrin is a protein that plays a crucial role in a specific type of cellular transport known as clathrin-mediated endocytosis. This process is essential for cells to internalize molecules from their external environment and for the trafficking of proteins within the cell.

In clathrin-mediated endocytosis, clathrin molecules assemble into a lattice-like structure on the inner surface of the cell membrane. This assembly is triggered by the binding of specific receptor proteins to their ligands outside the cell. The clathrin coat then deforms the membrane, causing it to bud inward and form a vesicle that encloses the internalized material. This vesicle eventually pinches off from the membrane and moves into the cytoplasm.

The term "klatriinivälitteinen" can be used to describe various cellular events that rely on this clathrin-dependent mechanism. For example, it might refer to the uptake of nutrients, the signaling pathways activated by receptor binding, or the recycling of membrane components. Understanding clathrin-mediated processes is vital for comprehending fundamental cellular functions and their dysregulation in diseases.
