A Ubiquitin-like Protein Involved in Membrane Fusion
نویسندگان
چکیده
Atg8 is a ubiquitin-like protein involved in autophagy in yeast that is targeted to membranes through conjugation to the lipid phosphatidylethanolamine (PE). In this issue of Cell, Nakatogawa et al. (2007) show that Atg8 conjugated to PE mediates tethering between adjacent membranes and stimulates membrane hemifusion, an event that may mimic expansion of the autophagosomal membrane during autophagy.

O-8: Molecular Mechanisms of Membrane Fusion Involved in Fertilization
Background: Assisted fertilization procedures are a currently widespread practice to regulate reproduction in humans and animals. The arising question is why the human being manipulating gametes to generate new individuals, if we do not understand yet the molecular mechanism of fertilization?. Successful completion of fertilization in mammals is dependent on three membrane fusion events: 1. the...
متن کاملGolgi reassembly after mitosis: the AAA family meets the ubiquitin family.
The Golgi apparatus in animal cells breaks down at the onset of mitosis and is later rebuilt in the two daughter cells. Two AAA ATPases, NSF and p97/VCP, have been implicated in regulating membrane fusion steps that lead to regrowth of Golgi cisternae from mitotic fragments. NSF dissociates complexes of SNARE proteins, thereby reactivating them to mediate membrane fusion. However, NSF has a sec...
متن کاملScreening and identification of SUMP-proteins in sub-acute treatment with diazinon
Objective(s):Small ubiquitin-like modifiers (SUMOs) are a family of ubiquitin-related, proteins that are involved in a wide variety of signaling pathways. SUMOylation, as a vital post translational modification, regulate protein function in manycellular processes. Diazinon (DZN), an organophosphate insecticide, causses oxidative stress and subsequently programmed cell death in different tissues...
متن کاملA complex of mammalian ufd1 and npl4 links the AAA-ATPase, p97, to ubiquitin and nuclear transport pathways.
The AAA-ATPase, p97/Cdc48p, has been implicated in many different pathways ranging from membrane fusion to ubiquitin-dependent protein degradation. Binding of the p47 complex directs p97 to act in the post-mitotic fusion of Golgi membranes. We now describe another binding complex comprising mammalian Ufd1 and Npl4. Yeast Ufd1p is required for ubiquitin-dependent protein degradation whereas yeas...
متن کاملThe Ubx2 and Ubx3 Cofactors Direct Cdc48 Activity to Proteolytic and Nonproteolytic Ubiquitin-Dependent Processes
Valosin-containing protein, VCP/p97 or Cdc48, is a eukaryotic ATPase involved in membrane fusion, protein transport, and protein degradation. We describe two proteins, Ubx2 and Ubx3, which interact with Cdc48 in fission yeast. Ubx3 is the ortholog of p47/Shp1, a previously described Cdc48 cofactor involved in membrane fusion, whereas Ubx2 is a novel protein. Cdc48 binds the UBX domains present ...
