  The classical ubiquitination pathway Ubiquitination is an enzymatic process that involves the addition of an ubiquitin protein to a substrate that usually becomes inactivated followed by degradation in the proteasome; however, several other functions have also been described. For the discovery of

  The major regulator of radiation sensitivity Tumor cell resistance to radiation is a big issue for radiation therapy, and a major concern of radiation oncologist. Understanding the regulation mechanism of radiation sensitivity is still a research hotspot. Increased sensitivity to ionizing radiati

  Does a universal mechanism for TLS exist? Our previous studies using the bacteriophage T4 DNA polymerase generated the model provided in Fig. 7 that quantifies the molecular forces influencing key steps in the polymerization pathway during the replication of a non-instructional versus miscoding DNA

  Introduction In mammals there are ten known isoforms of the enzyme diacylglycerol kinase (DGK), as well as gene splice variants. Enzymes of this family all have a homologous active site but differ widely in their molecular mass, mechanisms of activation and biological function (Shulga et al., 201

  Sphingosine kinase One of the enzymes closely related to DGKs are the sphingosine kinases (SKs). These enzymes catalyze the conversion of sphingosine (Sph) to sphingosine-1-phosphate (S1P). SKs and DGKs are closely related lipid kinase in term of basic enzymology and the mechanism of regulation a

  The transcriptome analysis of barley seeds in two tissue fractions: starchy endosperm/aleurone and embryo/scutellum, during maturation, desiccation and germination, revealed the large group of GA-responsive genes (Sreenivasulu et al., 2008). These transcripts have been divided into two groups. Nearl

  The excitatory amino protein kinase L-glutamate or glutamate mediates most of the excitatory neurotransmission within the mammalian central nervous system (CNS) and has been implicated in numerous peripheral nervous system (PNS) pathways. The excitatory amino acids, including glutamate, are of grea

  Pyrazolopyrimidines are bioisostere of purine exhibit promising antitumor activity by competitively binding to the ATP active site of different kinase Adrucil [16,17]. Several compounds of this family were found to induce apoptosis and/or reduce cell proliferation in various solid tumour and leukae

  Among prostaglandins (PG), PGD2 remained the most elusive species for a long time and was initially regarded as having negligible biological activity [1]. In 1974 its inhibitory effect on platelet aggregation was discovered by Smith et al. [2] and Mills & McFarlain [3], and both pressor and depresso

  Findings from the present study indicate that CRF1 receptors are especially important in fear acquisition.

  Introduction It has been well stablished the role of CRF in somatic pain regulation (Yarushkina et al., 2011, Yarushkina et al., 2016). However, the effects of CRF in pain relief are controversial and it has been described anti- and pronociceptive effects (Ji et al., 1995, Larauche et al., 2009, Ni
