Catalysis of the transfer of an malonyl (HOOC-CH2-CO-) group to an acceptor molecule.

A change in state or activity of the organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of exposure to mercuric ions (Hg2+).

A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters across the synaptic cleft and transmit the signal to the postsynaptic membrane.

Catalysis of the reaction: S-adenosyl-L-methionine + m(7)G(5')PPPAM = S-adenosyl-L-homocysteine + m(7)G(5')PPPM(6)AM.

The formation from simpler components of neurotransmitter receptors.

Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a guanine residue in a tRNA molecule.

The chemical reactions involving neurotransmitter receptors.

intercellular junction assembly and/or maintenance

The assembly and maintenance of junctions between cells.

The maintenance of junctions between cells.

Any process that modulates the activity of an enzyme.

A class of nuclear body, first seen after silver staining by Cajal in 1903, enriched in small nuclear ribonucleoproteins, and certain general RNA polymerase II transcription factors; ultrastructurally, they appear as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter; involved in aspects of snRNP biogenesis; the protein coilin serves as a marker for Cajal bodies. Some argue that Cajal bodies are the sites for preassembly of transcriptosomes, unitary particles involved in transcription and processing of RNA.

Any process that modulates the frequency, rate or extent of a physiological process, a processes specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms.

The directed movement of proteins into, out of, within or between cells.

Any process that modulates the rate or extent of the viral life cycle, the set of processes by which a virus reproduces and spreads among hosts.
