Protein degradation via UPP involves two steps One step
2021-04-02
Protein degradation via UPP involves two steps. One step is the conjugation of multiple ubiquitin to a substrate. The other step is the degradation of tagged protein by the downstream 26S proteasome complex. Protein ubiquitination is the E1–E2–E3 enzymatic cascade (Hershko & Ciechanover, 1998). E1-a

2021-04-02
There is a functional ubiquitin association (UBA) domain at the N terminus of MCPIP1. Liang et al. have discovered that MCPIP1 may be a deubiquitinase and defined a novel DUB domain of MCPIP1 [22]. Ubiquitin and deubiquitin modification emerge as the key mechanisms that regulate the virus-induced ty

Ubiquitylation of the TGFβ/BMP pathway components Ubiquitylation is a reversible post-translational modification that is essential in many cellular regulatory mechanisms [20], [21]. During the ubiquitylation cascade, ubiquitin is attached to target proteins through the concerted actions of an E1-

Materials and methods Results Discussion DNA-PKcs and the Ku heterodimer (Ku70 and Ku80) constitute the DNA-PK complex, which is a serine/threonine kinase. DNA-PK phosphorylates H2AX and other substrates, such as main NHEJ factors (Artemis, XRCC4, and DNA ligase IV) [4]. Therefore, DNA-PK d

Cdc42, which is involved in filopodium formation, and Rac1, which is involved in lamellipodium formation, engage in cross-talk with one another [25,26,30,31]. In general, filopodium formation precedes lamellipodium formation, and filopodium formation (Cdc42 activity) suppresses lamellipodium formati

Eleutherococcus senticosus (Rupt. & Maxim.) Maxim is a shrub belonging to the Araliaceae, which is commonly distributed in China, Korea, Japan and Russia. It has been traditionally used as folk medicine for the treatment of rheumatism, diabetes, and hepatitis (Nan et al., 2004). Recent phytochemical

Various domains of DDR1 have been shown to be important for receptor clustering and its oligomeric status. It is now understood that (i) dimerization [7] and higher-order oligomerization [12], [18] of the DDR1 extracellular domain (ECD) enhance its binding to collagen; (ii) DDR1 exists as non-covale

Introduction Noncanonical nucleoside triphosphates (NTPs; such as deoxyinosine triphosphate (dITP), deoxyxanthosine triphosphate (dXTP), 8-oxo-deoxyguanosine triphosphate, and 2-oxo-deoxyadenosine triphosphate are produced from oxidation, deamination, or other modifications of canonical nucleotid

Increased leukocyte trafficking and infiltration of the vascular wall are thought to provide a key stimulus for SMC activation and subsequent neointima formation in response to vascular injury [19], [20]. The essential trigger regulating the accumulation of leukocytes in the vessel wall is the upre

We propose the following model for how B cell-guiding EBI2 ligand gradients are established in lymphoid tissues. CH25H and CYP7B1 are needed in radiation-resistant stromal cells, are abundantly expressed and active in CXCL13+ and CCL21+ FRCs, but not lymphocytes, and are poorly expressed in the inne

In addition to demonstrating the importance of DNMTs, we show that TGFβ1 differentially regulated DNMTs, and that TGFβ1 is both necessary and sufficient to induce lineage conversion of hepatocytes into MLCs with phenotypes and multipotency resembling MSCs. Upon withdrawal of TGFβ1 on day 28, we obse

Electron transport via DHODH activity will allow the generation of mitochondrial ROS without the consumption of α-ketoglutarate or NADH. Glutamine-dependent flux through the TCA cycle and oxidative phosphorylation can also enable generation of mitochondrial ROS (Weinberg et al., 2010). The latter pr
