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.

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.

Acetylcholine is a major neurotransmitter and neuromodulator both in the central and peripheral nervous systems. It also acts as a paracrine signal in various non-neural tissues.

positive regulation of T cell proliferation

positive regulation of T-lymphocyte proliferation

Any process that activates or increases the rate or extent of T cell proliferation.

The formation from simpler components of acetylcholine, the acetic acid ester of the organic base choline.

positive regulation of activated T cell proliferation

positive regulation of activated T-lymphocyte proliferation

Any process that activates or increases the rate or extent of activated T cell proliferation.

calcium- and calmodulin-responsive adenylate cyclase activity

The formation from simpler components of spermidine, N-(3-aminopropyl)-1,4-diaminobutane.

Catalysis of the sequential cleavage of mononucleotides from a free 3' terminus of a DNA molecule.
