The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The chemical reactions and pathways involving 3'-phosphoadenosine 5'-phosphosulfate, a naturally occurring mixed anhydride. It is an intermediate in the formation of a variety of sulfo compounds in biological systems.

The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages.

The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The controlled release of proteins from a cell.

The binding and fusion of a sperm, with the plasma membrane of the oocyte as part of the process of single fertilization. In sperm with flagella, binding occurs at the posterior (post-acrosomal) region of the sperm head.

The chemical reactions and pathways involving collagen, any of a group of fibrous proteins of very high tensile strength that form the main component of connective tissue in animals. Collagen is highly enriched in glycine (some regions are 33% glycine) and proline, occurring predominantly as 3-hydroxyproline (about 20%).

Any process that modulates the frequency, rate or extent of locomotion of a cell or organism.

Synthesis and deposition of a collagen and cuticulin-based noncellular, hardened, or membranous secretion from an epithelial sheet, occurring as part of the molting cycle. An example of this process is found in Caenorhabditis elegans.

Synthesis and deposition of a collagen and cuticulin-based noncellular, hardened, or membranous secretion from an epithelial sheet, occurring as part of the molting cycle. An example of this process is found in Caenorhabditis elegans.

The negative regulation of fertilization process that takes place as part of egg activation, ensuring that only a single sperm fertilizes the egg.

Any process that modulates the rate, frequency, or extent of nematode larval development, the process whose specific outcome is the progression of the nematode larva over time, from its formation to the mature structure. Nematode larval development begins with the newly hatched first-stage larva (L1) and ends with the end of the last larval stage (for example the fourth larval stage (L4) in C. elegans). Each stage of nematode larval development is characterized by proliferation of specific cell lineages and an increase in body size without alteration of the basic body plan. Nematode larval stages are separated by molts in which each stage-specific exoskeleton, or cuticle, is shed and replaced anew.

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The component of the Golgi membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the Golgi membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions.

The network of interconnected tubular and cisternal structures located within the Golgi apparatus on the side distal to the endoplasmic reticulum, from which secretory vesicles emerge. The trans-Golgi network is important in the later stages of protein secretion where it is thought to play a key role in the sorting and targeting of secreted proteins to the correct destination.
