Spectrin folding unfolding

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. WebApr 1, 2008 · Spectrin (Sp), a key component of the erythrocyte membrane, is routinely stretched to near its fully folded contour length during cell deformations. Such dynamic …

Uniwersytet Wrocławski, Zakład Cytobio- 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.

Finally, single-molecule unfolding by atomic force microscopy indicates that the mutant construct has lost mechanical resiliency, consistent with destabilization of spectrin repeats.

WebAbstract. The elongated three-helix-bundle spectrin domains R16 and R17 fold and unfold unusually slowly over a rough energy landscape, in contrast to the homologue R15, which folds fast over a much smoother, more typical landscape. R15 folds via a nucleation–condensation mechanism that guides the docking of the A and C-helices.
