Autographa californica Multiple Nucleopolyhedrovirus AC83 is a Per Os Infectivity Factor (PIF) Protein Required for Occlusion-Derived Virus (ODV) and Budded Virus Nucleocapsid Assembly as well as
TLDR
The function of AC83, a protein that copurifies with the ODV PIFs, was reexamined and a new model for AC83 function was proposed and AC83 was found to be physically located in both the envelope and nucleocapsid of ODV.
Allatostatins: A Growing Family of Neuropeptides with Structural and Functional Diversity
Abstract: The high degree of conservation of the core sequence of the “cockroach‐types” of AST and their widespread distribution suggest that they should be considered a ubiquitous family of peptides
Molecular cloning of the gene for the allatostatin family of neuropeptides from the cockroach Diploptera punctata.
TLDR
A cDNA from the cockroach Diploptera punctata is isolated that encodes a 41.5-kDa precursor polypeptide containing the AST family of peptides, and in situ hybridization indicated the AST-encoding gene is expressed in neurosecretory cells of D. punctata brain.
A transporter for phenolamine uptake in the arthropod CNS.
TLDR
A preliminary investigation into the true extent of the distribution of this type of transporter using RT-PCR with a set of degenerate primers selective for monoamine transporters on cDNAs made from the nervous systems of a range of arthropods suggests that there are various invertebrates that appear to have evolved alternate ways of recycling phenolamine neurotransmitters released at the nerve synapse.
Comparison of the allatostatin neuropeptide precursors in the distantly related cockroaches Periplaneta americana and Diploptera punctata.
TLDR
Describing cDNA and genomic DNA sequences that specify a preproallatostatin precursor in the oviparous cockroach Periplaneta americana revealed several common features, including that the precursors are remarkably similar in size and the organization of the peptides within the precursor is conserved.
Frameshift autoregulation in the gene for Escherichia coli release factor 2: partly functional mutants result in frameshift enhancement.
TLDR
In vivo these chimeric proteins promote large increases in frameshifting at the RF-2 frameshift region, thereby reversing normal negative autoregulatory feedback and instead supporting fully efficient frameshifted in their own synthesis.
In situ hybridization analysis of leucomyosuppressin mRNA expression in the cockroach, Diploptera punctata
TLDR
Immunohistochemistry with a polyclonal antiserum generated against FMRFamide, but which recognizes extended RFamide peptides, demonstrated numerous RFamide‐like immunoreactive cells and processes in both nervous and nonnervous tissues, suggesting that LMS may play a central role in Diploptera and may be associated with feeding and digestion.
