Coordinated Induction of the Ubiquitin Conjugation Pathway Accompanies the Developmentally Programmed Death of Insect Skeletal Muscle (*)

The developmentally programmed cell death of abdominal intersegmental muscles in the tobacco hawkmoth Manduca sexta is coincident with a 10-fold induction of the polyubiquitin gene as a hormonally

Post-transcriptional regulation of gene expression during the programmed death of insect skeletal muscle

Data suggest that there may be global removal of cellular transcripts just prior to death to allow newly expressed mRNAs to rapidly accumulate to high levels and facilitate the efficient activation of death (and perhaps other differentiation programs) in some developmental systems.

Developmental Changes of the 26 S Proteasome in Abdominal Intersegmental Muscles of Manduca sexta during Programmed Cell Death (*)

A large increase in the concentration of 26 S proteasomes together with extensive regulatory reprogramming may facilitate rapid muscular proteolysis.

Regulation of apoptosis by ubiquitination

This review focuses on the direct effects of ubiquitination on apoptosis‐signaling molecules and reports of polyubiquitin conjugation of key pro‐ and anti‐apoptotic molecules as an essential regulatory modification targeting proteins for proteasomal degradation.

The ubc-2 gene of Caenorhabditis elegans encodes a ubiquitin-conjugating enzyme involved in selective protein degradation

Cl cloning and characterization of a gene (ubc-2) encoding a ubiquitin-conjugating enzyme which is involved in the selective degradation of abnormal and short-lived proteins in the nematode Caenorhabditis elegans suggest that yeast UBC4 and UBC5, Drosophila UbcD1, and C. elegans ubc-2 define a highly conserved gene family which plays fundamental roles in all eukaryotic cells.

The ubiquitin system

This review discusses recent information on functions and mechanisms of the ubiquitin system and focuses on what the authors know, and would like to know, about the mode of action of ubiquitIn-protein ligation systems and about signals in proteins recognized by these systems.

Role of ubiquitin conjugating enzymes in Drosophila development

The role of the ubiquitin system in development is addressed using Drosophila melanogaster as a model system, with particular developmental roles for the E2 genes suggested, as RNA from all known E2s was found to be abundant in this tissue in embryos.

Links between the Ubiquitin-Proteasome System and Cell Death Pathways in Arabidopsis thaliana

It could be shown that exposure to additional, normally harmless stress factors is able to accelerate the cell death process, and the isolation and characterization of suppressor of UbK48R-induced cell death (sud) mutants indicated changes in distinct, rather specialized pathways.

While the ubiquitin/26S proteasome pathway is responsible for the degradation of the bulk of cellular proteins during homeostasis, it may also beresponsible for the rapid loss of protein during the programmed death of certain cells, such as skeletal muscle during insect metamorphosis.

Localization of immunoreactive ubiquitin in the nervous system of the Manduca sexta moth

Investigation of the adbominal gaglia of Manduca sexta suggests that this protein plays a number of important roles in neuronal physiology and may be associated with the death of some neurons in this tissue, and the most intense staining of neuronal cytoplasm was found not in dying neurons, but in sets of persisting neurons that may serve a primarily neurosecretory or neuromodulatory function.



Structure and expression of ubiquitin genes of Drosophila melanogaster

Two related ubiquitin genes from Drosophila melanogaster, polyubiquitin and UB3-D are isolated and characterized and the pattern of expression of the polyubanquitin-lacZ fusion gene was investigated, which was expressed at high levels in a tissue-general manner at all life stages assayed.

Gene activation is required for developmentally programmed cell death.

The data presented here indicate that programmed cell death is not due to the cessation of macromolecular synthesis in condemned cells but rather is due toThe activation of a differentiative pathway.

An ancient developmental induction: heat-shock proteins induced in sporulation and oogenesis.

A strikingly similar pattern of expression occurs during oogenesis in Drosophila, suggesting that it may be one of the earliest developmental pathways to evolve in eukaryotic cells.

Degradation of proteins with acetylated amino termini by the ubiquitin system

The results suggest that a novel conjugating enzyme (possibly a ubiquitin-protein ligase) may be responsible for the degradation of these acetylated proteins by recognizing structural features of the substrate that are downstream and distinct from the NH2-terminal residue.

Cascade induction of c-fos, c-myc, and heat shock 70K transcripts during regression of the rat ventral prostate gland.

Analysis of RNA extracted from regressing ventral prostate glands showed that the c-fos gene was induced at 36 h, earlier than c-myc, alpha-tubulin, and hsp 70, and later, during the most active period of cell death, their expression was transiently induced.

The yeast ubiquitin genes: a family of natural gene fusions.

itin genes are expressed in exponentially growing cells, while in stationary‐phase cells the expression of UB11 and UB12 is repressed, and it is shown that the essential function of the UB14 gene is to provide ubiquitin to cells under stress.
