Structures of two repeats of spectrin suggest models of flexibility
-
1 Grum VL, Li D, MacDonald RI, Modragon A: Structures of two repeats of spectrin suggest models of flexibility. Cell 1999, 98:1-20. The linker region connecting two repeating units has been determined to be α-helical in five crystal structures of four cloned fragments of chicken brain α-spectrin. Two of the first molecular models of spectrin flexibility are proposed, based on two additional observations: conformational rearrangement consisting of a loop-to-helix transition and variable degrees of bending at the helical linker region.

Single molecule force spectroscopy of spectrin repeats: Low unfolding forces in helix bundles
-
2 Rief M, Pascual J, Saraste M, Gaub HE: Single molecule force spectroscopy of spectrin repeats: low unfolding forces in helix bundles. J Mol Biol 1999, 286:553-561. This paper describes AFM experiments in which single spectrin molecules are reversibly unfolded. When stretched the all α coiled coil structure of spectrin repeats unfolds at forces that are 5 to 10 times lower than those required to unfold the all β immunoglobulin domains of the muscle protein titin. This difference in mechanical stability may be explained by the lack of interstrand hydrogen bonds in the all α structure of spectrin.

This paper appears to be the first to fully incorporate the nonlinear, anisotropic mechanics of the general type suggested for spectrin by Rief et al. (J Mol Biol 1999, 286:553-561).

Membrane dynamics of the water transport protein aquaporin-1 in intact human red cells
-
13 Cho MR, Knowles DW, Smith BL, Moulds JJ, Agre P, Mohandas N, Golan DE: Membrane dynamics of the water transport protein aquaporin-1 in intact human red cells. Biophys J 1999, 76:1136-1144. This paper compares the diffusion of antibody-labeled aquaporin as obtained by fluorescence recovery after photobleaching and fluorescence-imaged microdeformation (Lee et al., Biophys J 1999, 77:853-864). Both methods reveal a low diffusivity for this important water channel and suggest significant interactions, perhaps similar to the steric interactions of band 3, with other membrane components.

Regulation mechanism of the lateral diffusion of band 3 in erythrocyte membranes by the membrane skeleton
-
16 Tomishige M, Sako Y, Kusumi A: Regulation mechanism of the lateral diffusion of band 3 in erythrocyte membranes by the membrane skeleton. J Cell Biol 1998, 142:989-1000. The authors were the first to apply single-particle tracking and optical trapping to band 3 and spectrin in the erythrocyte membrane. These microrheology technologies promise to be of growing importance to structure-function studies of the erythrocyte membrane.
