Any process that stops, prevents or reduces the frequency, rate or extent of protein catabolic process.

Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates.

Combining with the biogenic amine serotonin and transmitting a signal across a membrane by activating some effector activity. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates.

Combining with somatostatin to initiate a change in cell activity. Somatostatin is a peptide hormone that regulates the endocrine system by signaling via G protein-coupled somatostatin receptors. Somatostatin has two active forms produced by proteolytic cleavage: a 14 amino acid peptide (SST-14) and a 28 amino acid peptide (SST-28).

Combining with a tachykinin neuropeptide and transmitting the signal across the membrane by activating an associated G-protein.

Combining with thyroid-stimulating hormone to initiate a change in cell activity.

Combining with thyrotropin-releasing hormone to initiate a change in cell activity.

Combining selectively with transferrin, and delivering transferrin into the cell via endocytosis. Transferrin is a major iron carrier protein in vertebrates.

Combining with vasoactive intestinal polypeptide to initiate a change in cell activity.

Any process that stops, prevents or reduces the frequency, rate or extent of histone H4-K16 acetylation.

Any process that decreases the rate, frequency, or extent of histone H4 acetylation, the modification of histone H4 by the addition of an acetyl group.

Any process that modulates the frequency, rate or extent of thyroid-stimulating hormone secretion.

Any process that modulates the rate, frequency, or extent of the regulated release of a peptide hormone from secretory granules.

Any process that stops, prevents or reduces the frequency, rate or extent of thyroid-stimulating hormone secretion.

Any process that decreases the rate, frequency, or extent of the regulated release of a peptide hormone from secretory granules.

Any process that stops, prevents or reduces the frequency, rate or extent of thyroid hormone generation.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways involving any hormone.

Any process that activates or increases the frequency, rate or extent of thyroid hormone generation.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways involving any hormone.

Any process that stops, prevents or reduces the frequency, rate or extent of histone H3-K9 acetylation.
