WebJul 31, 2014 · The interactions of clathrin and adapter proteins during the early stages of CME is shown in Figure 1. CALM and adaptor protein complex 2 (AP2) accumulate at sites of enriched PtdIns(4,5)P2, via binding of specific basic sequences. CALM interacts directly with the α subunit of AP2. Cytosolic clathrin is recruited by the β2 subunit of AP2. WebHeterotetrameric clathrin adaptor protein complexes (APs) orchestrate the formation of coated vesicles for transport among organelles of the cell periphery. AP1 binds membranes enriched for phosphatidylinositol 4-phosphate, such as the trans Golgi network, while AP2 associates with phosphatidylinositol 4,5-bisphosphate of the plasma membrane.

WebAdaptor proteins such as AP-2, AP180 and CALM (Clathrin-assembly lymphoid myeloid leukaemia protein), which accumulate within the lipid bilayer, are responsible for the recruitment of the triskelion shaped Clathrin trimer. This trimer does not interact with the membrane directly but instead forms a reinforcing lattice structure that acts as a mold in … WebFeb 26, 2024 · LRK-1/LRRK2 and the clathrin adaptor protein complex AP-3 are critical for the separation of lysosomal proteins from SVp transport carriers. In lrk-1 mutants, both SVp carriers and SVp carriers containing lysosomal proteins are independent of UNC-104, suggesting that LRK-1 plays a key role in ensuring UNC-104-dependent transport of SVps. income guidelines for medicaid application
