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 sequestering of proteins making up these structures. These structures contain binding sites that katanin (“KAT-ah-nin”) and CLASP (“clasp”) proteins compete for. (15[2])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. Mitotic spindles are constructed from, for 10 points, what cytoskeletal polymers made up of tubulin subunits? ■END■
