The Ufm1-cascade of C. elegans
Background: The novel ubiquitin-like modifier (UBL) Ufm1 has essential functions in mammalian embryonic development. Results: The Ufm1-cascade in Caenorhabditis elegans is required for normal growth and development and is involved in cellular stress response. Conclusions: The C. elegans Ufm1-cascade is an antagonist of the unfolded protein response Significance: The C. elegans Ufm1-cascade offe...
متن کاملDeletion of Ubiquitin Fold Modifier Protein Ufm1 Processing Peptidase Ufsp in L. donovani Abolishes Ufm1 Processing and Alters Pathogenesis
Previously, we showed Leishmania donovani Ufm1 has a Gly residue conserved at the C-terminal region with a unique 17 amino acid residue extension that must be processed prior to conjugation to target proteins. In this report, we describe for the first time the isolation and characterization of the Leishmania Ufm1-specific protease Ufsp. Biochemical analysis of L. donovani Ufsp showed that this ...
متن کاملUbiquitin Fold Modifier 1 (UFM1) and Its Target UFBP1 Protect Pancreatic Beta Cells from ER Stress-Induced Apoptosis
UFM1 is a member of the ubiquitin like protein family. While the enzymatic cascade of UFM1 conjugation has been elucidated in recent years, the biological function remains largely unknown. In this report we demonstrate that the recently identified C20orf116, which we name UFM1-binding protein 1 containing a PCI domain (UFBP1), and CDK5RAP3 interact with UFM1. Components of the UFM1 conjugation ...
متن کاملStructure of ubiquitin-fold modifier 1-specific protease UfSP2.
Ubiquitin-fold modifier 1 (Ufm1)-specific protease 2 (UfSP2) is a cysteine protease that is responsible for the release of Ufm1 from Ufm1-conjugated cellular proteins, as well as for the generation of mature Ufm1 from its precursor. The 2.6 Å resolution crystal structure of mouse UfSP2 reveals that it is composed of two domains. The C-terminal catalytic domain is similar to UfSP1 with Cys(294),...
متن کاملThe Ufm1 Cascade
The ubiquitin-fold modifier 1 (Ufm1) is a posttranslational modifier that belongs to the ubiquitin-like protein (UBL) family. Ufm1 is present in nearly all eukaryotic organisms, with the exception of fungi. It resembles ubiquitin in its ability to be ligated to other proteins, as well as in the mechanism of ligation. While the Ufm1 cascade has been implicated in endoplasmic reticulum functions ...
