An ultrasensitive enzyme immunoassay (immune complex transfer enzyme immunoassay) of antibody immunoglobulin G (IgG) to human immunodeficiency virus type 1 (HIV-1) has been developed using recombinant HIV-1 reverse transcriptase (rRT) as antigen. However, some disadvantages were noted in the use of rRT as antigen: rRT was produced only with low efficiency in widely used strains of Escherichia c...
The function of insulin receptor substrate-1 (IRS-1) is regulated by both tyrosine and serine/threonine phosphorylation. Phosphorylation of some serine/threonine residues in IRS-1 dampens insulin signaling, whereas phosphorylation of other serine/threonine residues enhances insulin signaling. Phosphorylation of human IRS-1 at Ser(629) was increased by insulin in Chinese hamster ovary cells expr...
Most females with seasonal affective disorder (SAD) exhibit atypical vegetative symptoms such as overeating, and weight gain when depressed. The serotonin 2C receptor (5-HT(2C)) plays a key role in control of appetite and satiety. A 5-HT(2C) Cys 23 Ser substitution, coded for by a single nucleotide polymorphism (Cys 23 Ser) within the 5-HT(2C) gene, has been shown to influence 5-HT(2C) function...
Phosphorylation of tau protein at Ser-262 has been shown to diminish its ability to bind to taxol-stabilized microtubules. The paired helical filaments (PHFs) found in Alzheimer's disease brain are composed of PHF-tau, which is hyperphosphorylated at multiple sites including Ser-262. However, protein kinase(s) able to phosphorylate this site are still under investigation. In this study, the abi...
3-phosphoinositide-dependent protein kinase-1 (PDK1) expressed in unstimulated 293 cells was phosphorylated at Ser-25, Ser-241, Ser-393, Ser-396 and Ser-410 and the level of phosphorylation of each site was unaffected by stimulation with insulin-like growth factor-1. Mutation of Ser-241 to Ala abolished PDK1 activity, whereas mutation of the other phosphorylation sites individually to Ala did n...
