Maintains the phosphorylation state of certain molecules by associating with them and preventing them from associating with active phosphatases, and thus inhibiting the enzyme activity without interacting with the enzyme. Often pertains to proteins belonging to dual-specificity phosphatase family but lacking critical active site residues.

The chemical reactions involving histamine, a physiologically active amine, found in plant and animal tissue and released from mast cells as part of an allergic reaction in humans.

The formation from simpler components of histamine, a physiologically active amine, found in plant and animal tissue and released from mast cells as part of an allergic reaction in humans.

The regulated release of gastric acid (hydrochloric acid) by parietal or oxyntic cells during digestion.

Catalysis of the reaction: ATP + H2O + Na+(in) + K+(out) = ADP + phosphate + Na+(out) + K+(in).

eye pigment precursor transporter activity

Catalysis of the reaction: ATP + H2O + eye pigment precursor(in) = ADP + phosphate + eye pigment precursor(out).

Catalysis of the reaction: a lipid hydroperoxide + 2 reduced glutathione = 2 H2O + lipid + 2 oxidized glutathione.

smooth endoplasmic reticulum calcium ion homeostasis

smooth endoplasmic reticulum calcium ion concentration regulation

The regulation of the levels, transport, and metabolism of calcium ions within the smooth endoplasmic reticulum of a cell or between the smooth endoplasmic reticulum and its surroundings.

Catalysis of the reaction: 2-methyl-3-phytyl-1,4-naphthoquinone + oxidized dithiothreitol + H2O = 2,3-epoxy-2,3-dihydro-2-methyl-3-phytyl-1,4-naphthoquinone + 1,4-dithiothreitol.

The modification of histone H3 by addition of a methyl group to lysine at position 9 of the histone.

A rise in body temperature above the normal, often as a response to infection.

A conditioned aversion to a specific chemical compound as a result of that compound being coupled with a noxious stimulus.

An acute behavioral change resulting from a perceived external threat.
