High impact information on APP1

  • Furthermore, these cofilin mutants provided an opportunity to distinguish in living cells those actin functions that depend specifically on filament turnover (endocytosis) from those that do not (cortical actin patch motility) [1].
  • Interactions of WASp, myosin-I, and verprolin with Arp2/3 complex during actin patch assembly in fission yeast [2].
  • Using a strain defective in polarized secretion and actin-patch organization, we showed that a change in actin-patch organization could be a consequence of the fusion of mistargeted vesicles with the plasma membrane [3].
  • These results suggest that Ark1p and Prk1p may be downstream effectors of signaling pathways that control actin patch organization and function [4].
  • Cortical recruitment of Sjl2 requires the actin patch component Abp1 [5].
