WebThree homologous spectrin domains have remarkably different folding characteristics. We have previously shown that the slow-folding R16 and R17 spectrin domains can be altered … WebJan 15, 2007 · The first AFM studies of forced unfolding of spectrin used a naturally occurring multidomain construct comprising domains R13–R18 from chicken brain α -spectrin. Domains unfolded independently at low forces, between 25 and 35 pN (at pulling speeds of 0.08–0.8 nm/ms), giving a gain in contour length (Δ Lc) of ∼31 nm.
WebSpherocytosis is a genetic disease that affects the membrane of a red blood cell. This disease decreases the ratio of surface area to volume of the erythrocyte translating into a less flexible cell. The greater packed the cell the more susceptible it is to rupture or breakdown of the membrane. WebJan 15, 2007 · Spectrin Domains Lose Cooperativity in Forced Unfolding Abstract Spectrin is a multidomain cytoskeletal protein, the component three-helix bundle domains are expected to experience mechanical force in vivo. In thermodynamic and kinetic studies, neighboring domains of chicken brain α -spectrin R16 and R17 have been shown to …
