Disease relevance of RCJMB04_23c5

  • The actin-binding site in alpha-actinin was further defined by expressing both wild-type and mutant actin-binding domains as fusion proteins in E. coli [1].
  • The blebs contained both actin and alpha-actinin [2].
  • Finally, we searched for the occurrence of a cross-linking protein in these cyanobacteria and identified a 105-kDa protein as an alpha-actinin-like protein using specific antibodies [3].

Biological context of RCJMB04_23c5

  • The sequence differs from that of smooth muscle alpha-actinin only in the region of the first EF-hand calcium-binding motif, where 27 residues in brain alpha-actinin are replaced by just 22 residues in the smooth muscle isoform [6].
  • Mutually exclusive splicing of calcium-binding domain exons in chick alpha-actinin [6].
  • Nebulette, a cardiac homologue of nebulin, colocalizes with alpha-actinin in the pre-myofibrils of spreading cardiomyocytes and has been hypothesized to play a critical role in the formation of the thin-filament-Z-line complex early during myofibrillogenesis [7].
  • Our results indicate that residues 86-117 and 350-375 comprise distinct binding sites for alpha-actinin on adjacent actin monomers [8].
  • Analysis of 800 residues of deduced amino acid sequence at the amino-terminal end revealed a strikingly conserved domain of integral of 230 residues that shows a high degree of sequence similarity to the amino-terminal domains of alpha actinin and dystrophin [9].

Analytical, diagnostic and therapeutic context of RCJMB04_23c5

  • The distribution of the mean squared displacements of these microspheres becomes progressively more asymmetric and wider for increasing concentration in alpha-actinin and, to a lesser extent, for increasing actin concentration, which suggests that F-actin networks become progressively heterogeneous for increasing protein content [29].
  • By immunoelectron microscopy the podocyte foot processes of the rat and human kidney have been shown to contain three major proteins of the contractile apparatus in muscle, i.e., actin, myosin, and the Z-line protein, alpha-actinin [30].
  • Assuming that actin, myosin, and alpha-actinin are arranged in a way that would allow the foot processes to generate contractile force this filament system might help the glomerular capillaries to resist the high intraluminal hydrostatic pressure as well as to actively modify the surface area for filtration [30].
  • In indirect immunofluorescence, these two views have revealed that desmin is present at the periphery of each Z disc, forming a network of proteinaceous collars within the Z plane. alpha-Actinin is localized within each disc, giving a face-on fluorescence pattern that is complementary to that of desmin [4].
  • Immunofluorescence microscope studies using these antisera revealed that Z-protein has the same distribution as alpha-actinin in isolated Z-disk sheets [31].
