Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.

The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.

A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.

The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

The specialization of the spermatid nucleus during the development of a spermatid into a mature male gamete competent for fertilization.

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The orderly movement of a cell specialized to produce haploid gametes through the embryo from its site of production to the place where the gonads will form.

The process whose specific outcome is the progression of a chaeta over time, from its formation to the mature structure. A chaeta is a sensory multicellular cuticular outgrowth of a specifically differentiated cell.

Any process that activates or increases the frequency, rate or extent of the addition of ubiquitin groups to a protein.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process.

The series of four asymmetric divisions undergone by the sensory organ precursor cells to generate cells that have distinct cell fates. For example, in the external sensory organ, the precursor cells give rise to one multidendritic neuron and four additional cells (the socket, shaft, sheath cells and the external sense neuron).

Covalent attachment of the ubiquitin-like protein NEDD8 (RUB1) to another protein.

Any process that stops, prevents, or reduces the frequency, rate or extent of programmed cell death that occurs in the compound eye retina.

The process in which the anatomical structures of the antenna are generated and organized.

The ubiquitination by a protein of one or more of its own amino acid residues, or residues on an identical protein. Ubiquitination occurs on the lysine residue by formation of an isopeptide crosslink.

A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 48 of the ubiquitin monomers, is added to a protein. K48-linked ubiquitination targets the substrate protein for degradation.

Any process that increases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes.

Any process that prevents the activation of an inactive cysteine-type endopeptidase.

Any process that activates or increases the frequency, rate or extent of border follicle cell migration.

Any process that prevents the activation of an inactive cysteine-type endopeptidase involved in an apoptotic process.

Any process that stops, prevents or reduces the frequency, rate or extent of cysteine-type endopeptidase activity involved in execution phase of apoptosis.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
