The chemical reactions involving folic acid, pteroylglutamic acid. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines.

Any process that modulates levels of neurotransmitter.

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

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.

A secretory organelle found in blood platelets, which is unique in that it exhibits further compartmentalization and acquires its protein content via two distinct mechanisms: (1) biosynthesis predominantly at the megakaryocyte (MK) level (with some vestigial platelet synthesis) (e.g. platelet factor 4) and (2) endocytosis and pinocytosis at both the MK and circulating platelet levels (e.g. fibrinogen (Fg) and IgG).

Catalysis of the hydrolysis of proteins and small-molecule substrates at Asn-Xaa bonds.

A receptor complex usually consisting of a TCR- (T cell receptor) alpha and beta chain heterodimer, two CD3-epsilon chains, a CD3-gamma chain, a CD3-delta chain and a zeta chain homodimer. The complex mediates antigen recognition, ultimately resulting in T cell activation.
