The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.

The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.

The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

Formation of terminal branches in the open tracheal system. These are long cytoplasmic extensions that form fine tubules that transport oxygen directly to the tissues. An example of the process is found in Drosophila melanogaster.

Any process that activates or increases the frequency, rate or extent of the addition of telomeric repeats by telomerase.

Any process that activates or increases the frequency, rate or extent of the addition of telomeric repeats by telomerase.

Creation of the central hole of a tube in an open tracheal system through which gases flow.

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

The aggregation, arrangement and bonding together of a set of components to form a pore complex. A pore complex is a small opening in a membrane that allows the passage of liquids and/or gases.

The process occurring in the embryo by which the anatomical structures of the post-embryonic eye are generated and organized.

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

The directed movement of a toxin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that activates or increases the frequency, rate or extent of establishment of protein localization to telomere.

Any process that activates or increases the frequency, rate or extent of establishment of protein localization to telomere.

Any process that activates or increases the frequency, rate or extent of protein localization to Cajal body.

Any process that activates or increases the frequency, rate or extent of telomerase RNA localization to Cajal body.

A multisubunit ring-shaped complex that mediates protein folding in the cytosol without a cofactor.

A multisubunit ring-shaped complex that mediates protein folding in the cytosol without a cofactor.

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

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

A multisubunit complex comprising the chaperonin-containing T-complex and several other components involved in mediating sperm-oocyte Interaction.

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

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

A multisubunit ring-shaped complex that mediates protein folding in the cytosol without a cofactor.

A multisubunit ring-shaped complex that mediates protein folding in the cytosol without a cofactor.

Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.

Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system.

The portion of a cell bearing surface projections such as axons, dendrites, cilia, or flagella that includes the nucleus, but excludes all cell projections.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
