heparan sulphate proteoglycan biosynthesis, polysaccharide chain biosynthesis

The formation from simpler components of polysaccharide chain component of heparan sulfate proteoglycan.

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.

heparan sulfate proteoglycan biosynthesis, enzymatic modification

heparan sulphate proteoglycan biosynthesis, enzymatic modification

The modification, often by sulfation, of sugars incorporated into heparan sulfate after polymerization.

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.

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.

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.

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.

A heterodimer consisting of alpha and a beta subunits that binds to and caps the barbed ends of actin filaments, nucleates the polymerization of actin monomers but does not sever actin filaments.

Complex composed of a V1 and a V0 domain to form an active V-type ATPase that functions as a proton pump.
