background: newcastle disease virus (ndv) is the causativeagent of the newcastle disease (nd), a highly contagiousdisease in birds that causes significant economic losses to thepoultry industry worldwide. nd is endemic in iran and outbreaksare reported regularly in commercial poultry flocks and differentspecies of birds. objectives:the current study was carried outto characterize ndv based on p...

abstract: background: rabies has been reported in all provinces and cities of iran, although there has been no molecular study regarding different groups and subgroups of rabies virus by phosphoprotein gene. in this study, firstly, 48 and then 85 recent rabies isolates recovered from cases reported throughout iran identified the evolutionary origins by molecular method of phosphoprotein gene re...

Objective: Coronaviruses are a group of similar viruses which cause fatal infection and responsible for affecting the upper respiratory tract in many organisms. Throughout time these have been found to affect human life by causing major pandemics like SARS, MERS COVID-19 due their high rate mutation zoonotic transmission. Repurposing drug could be solution this challenge, as previously availabl...

Preparations of the "induced protein" which appears in the rat uterus within 40 min of estradiol administration have recently been reported to contain phosphoprotein phosphatase (phosphoprotein phosphohydrolase, EC 3.1.3.16) activity. We found that these two proteins distribute differently on ammonium sulfate fractionation of uterine cytosol. Preparative cellulose acetate electrophoresis afford...

A peptide that is rich in organically bound phosphorus and contains abundant serine residues has been identified in the dentin of man (1), fetal bovine (2, 3), and rat (4). This phosphoprotein may play a role in mineralization (5-9). Butler et al. (4) reported that the phosphoprotein of rat incisor dentin constituted 10.8% of the proteinaceous material recovered from decalcified incisor teeth w...

Exchange of sarcoplasmic reticulum phospholipids with dipalmitoyllecithin inhibits the (Mg2+ + Ca2+)-activated ATPase activity below 40 degrees by inhibition of the decomposition of phosphoprotein intermediate. The rate of phosphoprotein formation and the steady state concentration of phosphoprotein measured by rapid kinetic techniques are affected to a lesser extent. The inhibitory effect of d...

BACKGROUND Wnt3a stimulates cellular trafficking of key signaling elements (e.g., Axin, Dishevelled-2, beta-catenin, and glycogen synthase kinase-3beta) and primitive endoderm formation in mouse F9 embryonic teratocarcinoma cells. RESULTS The role of phosphoprotein phosphatase-2A in signaling of the Wnt/beta-catenin/Lef-Tcf-sensitive gene activation pathway was investigated. Wnt3a action atte...
