By using rate-based flow control, out-of-band retransmissions, and aligning the size of protocol segments and end-system memory pages, the protocol (“Zing”) described in this paper enables efficient schedulable bulk data transfer over optical lightpaths.

Zinc finger domains of the classical type represent the most abundant DNA binding domains in eukaryotic transcription factors. Plant proteins contain from one to four zinc finger domains, which are characterized by high conservation of the sequence QALGGH, shown to be critical for DNA-binding activity. The Arabidopsis thaliana SUPERMAN protein, which contains a single QALGGH zinc finger, is nec...

TFIIIA, a site-specific DNA-binding protein containing nine zinc finger motifs, is an RNA polymerase III transcription factor responsible for the assembly of a transcription complex on the 5 S RNA gene. We have analyzed the effect of deleting various regions of yeast TFIIIA on its ability to bind to the internal control region of the yeast 5 S RNA gene, to recruit TFIIIC into the TFIIIA.DNA com...

The paper summarizes the current state of our work addressing the verification of Windows kernel drivers via model checking technique. Our goal is to implement a tool that extracts verification models using driver source code and specifications of the kernel environment written in DeSpec language, which we introduced previously. The DeSpec language enables specifying the kernel environment as w...

Recurring chromosomal translocations observed in human leukemia often result in the expression of fusion proteins that are DNA-binding transcription factors. These altered proteins acquire new dimerization properties that result in the assembly of inappropriate multimeric transcription complexes that deregulate hematopoietic programs and induce leukemogenesis. Recently, we reported that the fus...

To localize the DNA binding domain of the Saccharomyces cerevisiae Ars binding factor 1 (ABF1), a multifunctional DNA binding protein, plasmid constructs carrying point mutations and internal deletions in the ABF1 gene were generated and expressed in Escherichia coli. Normal and mutant ABF1 proteins were purified by affinity chromatography and their DNA binding activities were analyzed. The sub...

The INDETERMINATE protein, ID1, plays a key role in regulating the transition to flowering in maize. ID1 is the founding member of a plant-specific zinc finger protein family that is defined by a highly conserved amino sequence called the ID domain. The ID domain includes a cluster of three different types of zinc fingers separated from a fourth C2H2 finger by a long spacer; ID1 is distinct fro...

A gene OsZnI encoding Cys3/His1-type zinc finger protein was isolated from the water stress-induced cDNA library of rice (Oryza sativa) cv. N-22, an early maturing, deep-rooted, drought-tolerant genotype adapted to upland conditions. The in-silico analysis revealed an insert of 800 bp with an ORF of 663 nucleotides, encoding 221 amino acids. OsZnI had three distinct features--nuclear localizati...

The genome of Bombyx mori nucleopolyhedrovirus (BmNPV) is predicted to contain six RING finger proteins: IAP1, ORF35, IAP2, CG30, IE2, and PE38. Several other members of the RING finger family have recently been shown to have the ubiquitin-ligase (E3) activity. We thus examined whether BmNPV RING finger proteins have the E3 activity. In vitro ubiquitination assay with the rabbit reticulocyte ly...
