After getting translated, proteins making up these structures often have their C-terminal tyrosine residues removed and replaced with glutamic acid and glycine chains. T2S complexes are formed from the stathmin-mediated sequestrating of proteins making up these structures. These structures contain binding sites that katanin (“KAT-ah-nin”) and CLASP (“clasp”) proteins compete for. In 1986, Kirschner and Mitchison proposed that these structures coordinate their synthesis using a “search-and-capture” mechanism. These structures nucleate from (*) gamma-TuRC-containing organizing centers known as MTOCs (“M-tocks”). These structures, which are composed of protofilament arrays, make up the internal structure of flagella. (10[1])Mitotic spindles are constructed from, for 10 points, what cytoskeletal (10[1]-5[1])polymers made up of tubulin (-5[1])subunits? (10[2]) ■END■
