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 chemical reactions involving tetrahydrofolate, 5,6,7,8-tetrahydrofolic acid, a folate derivative bearing additional hydrogens on the pterin moiety.

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

heparan sulfate proteoglycan biosynthesis, polysaccharide chain biosynthesis

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.
