Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

In the gel shown in Figure 8, at early time-points, 14% of the input dsDNA is converted to these intermediate species. These persist in the gel to later times, with approximately 50% of these being unwound. This unwinding occurs at a considerably slower rate and is due to that fraction of the popula

Materials and methods Results Discussion Our previous investigation demonstrated that some genes in the latex that were involved in rubber biosynthesis were regulated by exogenous JA, and Hbvp1 is one of the JA-responsive genes in the latex of rubber trees [23]. In this study, the Hbvp1 enc

Group B phytocystatins are also expressed in caryopses. Although their expression patterns during germination are similar to those of the group A inhibitors, their expression patterns during seed development vary, indicating that they play different roles in the latter process. The highest levels of

Materials and methods Results Discussion CDK4 has been identified recently as a potential therapeutic target in human breast cancer, liposarcoma, melanoma, and glioblastoma [[37], [38], [39]]. Due to the importance of CDK4 activity in cancer cells, CDK4 inhibitors have emerged as promising

Third, we also found negative correlations between TREM2 mRNA expression and the methylation rate of 4 CpG sites in the intron 1 of TREM2. Gene methylation rates are generally associated with gene expression. Thus, heavily methylated areas of genes are usually less active at the transcriptional leve

In SLO-permeabilized human sperm, the AR elicited by calcium, persistently active Arf6 [41] and Rab3A, 8-pCPT-2′-O-Me-cAMP [8], diacylglycerol and a non-hydrolyzable analog [35], is sensitive to the PLC blocker U73122. Furthermore, 8-pCPT-2′-O-Me-cAMP elicits a calcium signal in non-permeabilized sp

Lymphocyte mobility and homing is modulated by the chemoattractant receptor subfamily of G protein-coupled receptors (GPCRs) (Campbell et al., 2003, Rot and von Andrian, 2004). B cell migration and position are controlled to a large extent by the lymphoid chemokines CXCL13, CXCL12, CCL19, and CCL21

Multi-subunit RING-type E3 ligases are exemplified by the CULLIN-RING-ligase (CRL) and the anaphase-promoting complex/cyclosome (APC/C) [19]. CRLs constitute the biggest family of other multi-component E3 ligases. These consist of a cullin scaffold protein (CULLIN 1, 2, 3, 4A, 4B, 5, 7), a substrate

Localization of D2 receptors in striatum One characteristic of D2Rs that has complicated their study is their expression in multiple neuronal populations within striatum, both pre- and postsynaptically (Beaulieu and Gainetdinov, 2011). In addition to spiny projection neurons (SPNs), which are the

In 2015–2016, half a century after its first biochemical characterization as a template-independent polymerase, it was shown that TdT can, firstly, assemble a DNA synapsis by itself, optimally with one micro-homology base-pair between strands [] and secondly, perform a template-dependent nucleotid

MTX and MTXPGs block the activity of the key enzyme DHFR (Fig. 1), which converts folates to their active forms – dihydrofolate (DHF) and tetrahydrofolate (THF). MTXPGs also potently inhibit thymidylate synthase (TS). Furthermore, during dTMP synthesis, TS utilizes the cofactor 5,10-methylene THF, w

Among the members of the GH106 family, which groups 319 different sequences, a single 3D-structure has been reported, the BT0986 from Bacteroides thetaiotaomicron that shows a (β/α)8 barrel and catalyzes the hydrolysis of an α-l-rhamnopyranoside bound to the C2 position of an arabinofuranoside (L-Rh
