The major integral plasma membrane protein (IP39) of Euglena gracilis was radiolabeled, peptide mapped, and dissected with proteases to identify cytoplasmic domains that bind and anchor proteins of the cell surface. When plasma membranes were radioiodinated and extracted with octyl glucoside, 98% of the extracted label was found in IP39 or the 68- and 110-kD oligomers of IP39. The octyl glucosi...

We previously reported specific interaction of cellular glyceraldehyde 3-phosphate dehydrogenase (GAPDH), the key glycolytic enzyme, and La protein, the RNA polymerase III transcription factor, with the cis-acting RNAs of human parainfluenza virus type 3 (HPIV3) and packaging of these proteins within purified virions (B. P. De, S. Gupta, H. Zhao, J. Z. Drazba, and A. K. Banerjee, J. Biol. Chem....

Objective(s) The fractions of Candida albicans have been used as an immunomodulator. The present work assessed the effect of different fractions of C. albicans on nitric oxide (NO) production by mice peritoneal macrophages. Materials and Methods Cell wall and cytoplasmic fractions of C. albicans ATCC 10321 strain were extracted. Mice peritoneal macrophages were purified and cultured. Differen...

CD5 is well recognized for its importance in thymic selection. Although this property of CD5 has been attributed to its ITIM-domain dependent regulation of TCR-signal strength, the mechanism has not been established. A second major signaling domain within the cytoplasmic tail of CD5 is a CK2 binding/activation domain (CD5-CK2BD). Using a gene-targeted mouse in which the CD5-CK2BD is selectively...

Two major impediments to infer plant phylogenies at inter- or intra- species level include the lack of appropriate molecular markers and the gene tree/species tree discordance. Both of these problems require more extensive investigations. One of the foci of this study is examining the phylogenetic utility of a combined chloroplast DNA dataset (>5.0kb) of seven non-coding regions, in comparison ...
