A DNA binding and dimerization motif, with apparent amphipathic helices (the HLH motif), has recently been identified in various proteins, including two that bind to immunoglobulin enhancers (E12 and E47). We show here that various HLH proteins can bind as apparent heterodimers to a single DNA motif and also, albeit usually more weakly, as apparent(More)
We have determined the nucleotide sequence of two transcription units of the AS-C and shown that their potential protein coding regions share two principal domains of homology. Both domains are conserved within the myc protein family, and one of them is highly homologous with the consensus for protein tyrosine kinase substrates. We show in addition that at(More)
Earlier work suggested that the wingless gene of Drosophila is required for cooperation within discrete groups of cells during development. We show that antisense RNA made from a 3 kb transcript produces wingless mutant phenocopies when injected into wild-type eggs, proving that this transcript executes the wingless function. In the accompanying paper,(More)
The achaete-scute gene complex (AS-C), involved in differentiation of the sensory chaetes of D. melanogaster, and the yellow locus have been cloned. The yellow locus is the most distal and is followed, proximally, by the achaete and the scute loci. In the scute locus (75 kb), three transcription units separated by long stretches of DNA give rise to poly(A)+(More)
Currently, there are a lot of e-learning and collaborative platforms to support distance and collaborative learning, however, all of them were designed just like an application without considering the network infrastructure below. Under these circumstances when the platform is installed and runs in a campus, sometimes it has very poor performance. This(More)
The expression of a subset of homologous genes of the AS-C is required during embryogenesis and metamorphosis for proper neural development. Here we study the expression of three of these genes (T3, T4, and T5) and show that their transcripts accumulate at the blastoderm stage in periodic patterns coincident with the dorsoventral extent of the(More)
It has been amply documented that herpes simplex virus (HSV) persists in sensory ganglia of the peripheral nervous system (PNS). In contrast, HSV latency in the central nervous system (CNS) has not been well characterized. Corneal inoculation of virus results in a productive viral infection in the CNS during the first week after inoculation, indicating that(More)
