A cDNA library was prepared from poly(A)+ RNA extracted from respiratory syncytial (RS) virus-infected HEp-2 cells. A recombinant plasmid, pRSP68, encoding the RS virus phosphoprotein gene was identified by translation in vitro of hybrid-selected mRNA. The cloned cDNA insert of 1 kb was sequenced and a polypeptide of 241 amino acids with a molecular weight of 27 166 was deduced from the sequenc...

We have characterized the BRCA1 gene product by using four polyclonal antibodies raised against peptides from four different regions of the protein. The antibodies specifically recognize an approximately 220-kDa BRCA1 protein that is predominantly expressed in the nucleus of both normal and neoplastic breast cancer cells. It is a serine phosphoprotein that undergoes hyperphosphorylation during ...

When a2p-labeled phosphoprotein is added to a suspension of calf thynms nuclei, the protein enters the nuclei and a rapid metabolic ' turnover ' of the previously incorporated phosphate groups occurs. The only a2P-labeled product which can be detected in these nuclei is inorganic phosphate. The results indicate that the phosphoprotein is probably not involved in the metabolic transfer of phosph...

Yak1 is a member of dual-specificity Tyr phosphorylation-regulated kinases (DYRKs) that are evolutionarily conserved. The downstream targets of Yak1 and their functions are largely unknown. Here, a homologous protein AtYAK1 was identified in Arabidopsis thaliana and the phosphoprotein profiles of the wild type and an atyak1 mutant were compared on two-dimensional gel following Pro-Q Diamond pho...

The intracellular pathogen Listeria monocytogenes is a useful model for general actin-based cell motility, because it recruits host actin and associated proteins for movement. Recent data have shown that these associated proteins include the Ena/VASP family of proteins and the actin-related proteins Arp2 and Arp3.

The structural stability of sulfolane (tetrahydrothiophene1,1-dioxide) and 3-sulfolene (dihydrothiophene1,1-dioxide) was investigated by DFT-B3LYP and ab initio MP2 calculations with 6-311+G**) basis set. The calculated symmetric ring-puckering potential of 3-sulfolene at the B3LYP level is consistent with a flat minimum that corresponds to a planar ring but at the MP2 level with a double minim...
