Ubiquitin-dependent mitochondrial protein degradation.
Progressive mitochondrial failure is tightly associated with the onset of many age-related human pathologies. This tight connection results from the double-edged sword of mitochondrial respiration, which is responsible for generating both ATP and ROS, as well as from risks that are inherent to mitochondrial biogenesis. To prevent and treat these diseases, a precise understanding of the mechanis...
متن کاملPirh2 promotes ubiquitin-dependent degradation of the cyclin-dependent kinase inhibitor p27Kip1.
The cyclin-dependent kinase inhibitor p27(Kip1) is degraded in late G(1) phase by the ubiquitin-proteasome pathway, allowing cells to enter S phase. Due to accelerated degradation of p27(Kip1), various human cancers express low levels of p27(Kip1) associated with poor prognosis. S-phase kinase-associated protein 2, the F-box protein component of an SCF ubiquitin ligase complex, is implicated in...
متن کاملUbiquitin-dependent degradation of active Src
Signaling by members of the Src family of protein tyrosine kinases, such as Src and Fyn, is important in many biological responses, including gene transcription, cell-cycle progression, and cell adhesion and spreading [1] [2]. Unregulated Src kinase activity has been implicated in the progression of colon cancer and transformation of cultured cells [3] [4] [5] [6]. Thus, precise regulation of S...
متن کاملLys6-modified ubiquitin inhibits ubiquitin-dependent protein degradation.
Ubiquitin plays essential roles in various cellular processes; therefore, it is of keen interest to study the structure-function relationship of ubiquitin itself. We investigated the modification of Lys(6) of ubiquitin and its physiological consequences. Mass spectrometry-based peptide mapping and N-terminal sequencing demonstrated that, of the 7 Lys residues in ubiquitin, Lys(6) was the most r...
متن کاملAtheroprotective Pulsatile Flow Induces Ubiquitin-Proteasome–Mediated Degradation of Programmed Cell Death 4 in Endothelial Cells
OBJECTIVES We recently found low level of tumor suppressor programmed cell death 4 (PDCD4) associated with reduced atherosclerotic plaque area (unpublished). We investigated whether atheroprotective unidirectional pulsatile shear stress affects the expression of PDCD4 in endothelial cells. METHODS AND RESULTS En face co-immunostaining of the mouse aortic arch revealed a low level of PDCD4 in ...
