Dominant Negative Mutant Actins Identified in Flightless Drosophila Can Be Classified into Three Classes

Multiple actins in drosophila melanogaster

The tissue and developmental specificities of the three Drosophila isoactins, originally identified in primary myogenic cultures and in the permanent Schneider L-2 cell line, have been investigated. Of these three isoactins (I, II, and III), actins I and II are stable and actin III is unstable. Two-dimensional polyacrylamide gel electrophoretic analyses of total cellular extracts after 1-h [(35...

Can Working Style be Identified?

Working style is a concept not fully taken into account especially when the unfolding of a business process is supported by Processaware Information Systems. In this paper we present a practical approach to define and identify working style. The identification is done by searching for some patterns representing critical common features which define a working style. A prototype is presented as a...

The ability of protein tyrosine phosphatase SHP-1 to suppress NFkappaB can be inhibited by dominant negative mutant of SIRPalpha.

In contrast with hematopoietic cells and fibroblasts, which express mainly one form of protein tyrosine phosphatase (PTP) SHP-1 or SHP-2, epithelial cells like A431, HeLa, and 293 express both forms of PTP. These two PTP regulate NFkappaB activity differently; SHP-1 inhibits and SHP-2 stimulates NFkappaB activation. In epithelial cells the process of NFkappaB activation depends on the combinati...

Pseudorabies virus can be classified into five genotypes using partial sequences of UL44

Suid herpesvirus 1 (SuHV-1) is the causative agent of pseudorabies (PR), a disease of great importance due to the huge losses it causes in the swine industry. The aim of this study was to determine a method for genotyping SuHV-1 based on partial sequences of the gene coding for glycoprotein C (gC) and to elucidate the possible reasons for the variability of this region. A total of 109 gCsequenc...
