A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The ESCRT (endosomal sorting complex required for transport) complexes and associated proteins mediate membrane scission reactions, such as multivesicular body formation, the terminal stages of cytokinesis and retroviral particle release. These proteins are believed to be sequentially recruited to the site of membrane scission, and then complexes are disassembled by the ATPase Vps4A. However, these events have never been observed in living cells, and their dynamics are unknown. By quantifying the recruitment of several ESCRT and associated proteins during the assembly of two retroviruses, we show that Alix progressively accumulated at viral assembly sites, coincident with the accumulation of the main viral structural protein, Gag, and was not recycled after assembly. In contrast, ESCRT-III and Vps4A were transiently recruited only when the accumulation of Gag was complete. These data indicate that the rapid and transient recruitment of proteins that act late in the ESCRT pathway and carry out membrane fission is triggered by prior and progressive accumulation of proteins that bridge viral proteins and the late-acting ESCRT proteins.
