A protein complex found on these cells is partly stabilized by beta-adducin and dematin. In these cells, a duo of membrane proteins assemble into antiparallel heterodimers that organize into a lattice network. These cells fail to rebound from elongation in hereditary ellipto·cytosis. (15[4])The plasma membrane of these cells is supported by band 4.1 (15[1])and ankyrin protein (15[1])complexes tethered (15[1])to spectrin (15[1])filaments. (15[2]10[1])These cells, (15[1])which mature from (-5[1])(*) reticulocytes, (10[6])can (10[1])be classified (10[2])based on (10[1])whether (-5[1])they express surface antigens terminated (-5[1])by GalNAc (10[1]-5[1])(“gal-nack”) or galactose. (10[1])A tetrameric protein found primarily in these cells in fetuses (10[1])is composed (10[1])of alpha and gamma (10[1])chains. Some of these cells express the Rh (-5[1])factor. (10[4]-5[1])For (10[1])10 points, name these (-5[1])biconcave (10[1]-5[1])cells (10[1])that can (10[1])be (10[1])classified (10[1])using the ABO system. ■END■ (10[8])
