The generation of a mature peptide hormone by posttranslational processing of a prohormone.

The rapid expansion of a lymphocyte population by cell division.

The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).

The formation from simpler components of the heparan sulfate proteoglycan, a glycosaminoglycan with repeat unit consisting of alternating (alpha1-

The formation of bone or of a bony substance, or the conversion of fibrous tissue or of cartilage into bone or a bony substance.

The uptake of neurotransmitters by presynaptic neurons or glial cells. This process leads to inactivation and recycling of neurotransmitters. It does not occur during cholinergic synaptic transmission. Instead, acetylcholine is enzymatically degraded in the synaptic cleft.

Any process that modulates levels of neurotransmitter.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate (PAPS) + N-desulfoheparin = adenosine 3',5'-bisphosphate + heparin.

acetylcholine catabolism in synaptic cleft

acetylcholine degradation in synaptic cleft

The breakdown into simpler components of acetylcholine that occurs in the synaptic cleft during synaptic transmission.

Catalysis of the reaction: UDP-glucuronate + 3-beta-D-galactosyl-4-beta-D-galactosyl-O-beta-D-xylosylprotein = UDP + 3-beta-D-glucuronosyl-3-beta-D-galactosyl-4-beta-D-galactosyl-O-beta-D-xylosylprotein.

Tethered to the plasma membrane by a covalently attached anchor, such as a lipid moiety, that is embedded in the membrane. When used to describe a protein, indicates that the peptide sequence does not span the membrane.

The lipid bilayer surrounding an organelle.

Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination.

The rapid expansion of a B cell population by cell division. Follows B cell activation.
