antibodies - 2025 PACE NSC

Question

A variant of these proteins with two additional transmembrane alpha-helices complexes with a dimer of "79a" and "79b" proteins. In CUT&RUN, these proteins are captured by Staph·ylo·coccus aur·eus's protein A and protein G. Components of these proteins (20[1])consist of 110-peptide (20[1])repeats (20[1])characterized by beta-sandwiches. (20[1])A second rearrangement (0[1])is needed to include diversity segments in these (20[2])proteins. (20[5])Genes (20[1])for receptors and these proteins are diversified via (20[1])(*) VDJ (10[4])recombination. (10[9])In these proteins, the hinge region connects the Fab ("FAB"), or constant, (10[1])and Fc, or variable, regions. (10[2])These (10[1])proteins' heavy and light chains form (10[1])a (10[2])"Y" shape. (10[3])For (10[1])10 points, name these (10[1])immune system proteins (10[3]0[1])that target antigens. ■END■ (10[1])

ANSWER: antibodies [immunoglobulins or Abs or Igs or IgGs or membrane-bound antibodies] (The dimer is CD79, which consists of CD79a and CD79b.)
