Introduction Prolyl hydroxylation is a widely observed post translational modification in collagen, an abundant animal protein. The high content (~13% per chain of the triple helical structure) of 4-hydroxyproline (Hyp,O) in collagen, togather with the natural abundance of collagen has led to the e

In different body organs, a number of biological functions are generally mediated by binding of the extracellular substances to the particular transmembrane receptors, which results in subsequent signal stimulation by intracellular signaling cascades. These cascades function over the complex network

Introduction Proteins play an important role in cellular functions; however, being and remaining properly folded is necessary for their function. Understanding the stability of the protein is necessary to investigate the folding of proteins, as well as their conformation, functions and interactions

Diacylglycerol kinases DGK and are lipid kinases
2021-03-12
Diacylglycerol kinases (DGK) α and ζ are lipid kinases that limit diacylglycerol (DAG)-dependent activation pathways downstream of the TCR (Merida et al., 2015). Their upregulation in tumor infiltrating lymphocytes (TIL) has been linked to generation of hyporesponsive states that contribute to immun

The pyrrolo[2,1-][1,4]benzodiazepines (PBDs) are a family of antitumour antibiotics that includes the natural products anthramycin and DC-81. They exert their cytotoxicity by covalently bonding to the exocyclic C2–NH group of guanine residues in the minor groove of DNA through their N10–C11 imine fu

Nociceptive and hyperalgesic actions of ET-1 are produced through ETA and ETB receptors. Previous reports indicate that ETA receptor antagonists in peripheral tissues are effective in inhibiting ET-1 induced hyperalgesia, and attenuation of neuropathic pain in rats [16]. Studies have also shown that

Two isoforms of intracellular ER, ERα, and ERβ, after binding to estrogens and translocate to the nucleus, activate some transcription factors and signaling pathways. The deregulation of estrogenic pathways can elevate transcriptional activity contributed to the development of cancer. Expression of

Our finding that VEGF-A induced downregulation of EphB4 is VEGFR2 dependent (Fig. 4A) is not surprising because VEGFR2 is the primary signaling receptor of VEGF-A in EC [34]. However, our finding that VEGF-A induced upregulation of dll4 vitamin d3 sources is not inhibited by VEGFR2 inhibition sugge

Multiple technologies exist for analyzing the contents of single cells, including single-cell DNA sequencing, RNA expression analysis, and protein level and activity measurements (Hu et al., 2018; Narrandes & Xu, 2018; Ortega et al., 2017; Wang & Navin, 2015). Single-cell DNA sequencing is generally

Ubiquitination is a reversible posttranslational modification. The removal of Ub is carried out by enzymes known as deubiquitinases (DUBs). The antagonistic role played by these enzymes in the Ub pathway regulates the function of the ubiquitinated proteins, while maintaining the free Ub pool in euka

To ascertain separation of the distinct enzymatic activities found in this protein preparation following separation on the HAP column, a rigorous quantitative analysis was conducted on the nickel–agarose elution and HAP FT pools of protein. For these analyses, each pool of protein was dialyzed in th

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
