Electroformation is used to generate the “giant unilamellar” type of these structures. (10[3])These structures can be assembled using a protein that has “helix-break-helix” motifs and is called caveolin-1. A protein (10[1])involved in assembling another type of (10[1])these structures contains PIP2 (“pip-two”)-binding ANTH (10[1])domains and links AP2 adaptor complexes (10[2])with a triskelion-shaped protein (10[1]-5[1])that coats (10[2])these structures. (10[5]-5[1])Rab GTPases (10[1])(“G-T-P-aces”) help tether these structures prior to SNARE (10[1])(“snair”)-mediated fusion. (10[7]-5[2])Sec13/31 (10[4]-5[1])(“seck-13-31”) is recruited to assemble COPII (10[1])(“cop-two”) complexes (10[2])around these structures, (10[1])which (-5[1])are analogous (10[1])to their clathrin-coated types. (10[2])Receptor-mediated (-5[1])endocytosis (-5[1])forms these structures, (-5[1])which also (10[2])compartmentalize (10[1])cargo (10[2])by the trans-Golgi (10[3])network. (10[4])For 10 points, (10[2])name these membrane-bound (10[1]-5[1])structures (10[1])used for (10[1]-5[1])trafficking. (10[1]-5[1])■END■ (10[11]0[8])
