A change in the state or activity of a cell (in terms of enzyme production, gene expression, etc.) as a result of the presence of unfolded proteins.

negative regulation of mitogen-activated protein kinase activity

Any process that stops, prevents or reduces the rate of MAPK activity.

unfolded protein response, activation of signaling protein activity

unfolded protein response, activation of signalling protein kinase/endonuclease

The conversion of a specific protein, possessing protein kinase and endoribonuclease activities, to an active form as a result of signaling via the unfolded protein response.

The breakdown into simpler components of any one of a family of organic molecules consisting of a pyrimidine base covalently bonded to a sugar deoxyribose (a deoxyribonucleoside).

The chemical reactions involving any ribonucleoside, a nucleoside in which purine base is linked to a ribose (beta-D-ribofuranose) molecule.

The processes involved in the specific binding of a viral antireceptor to a cell surface receptor.

The processes required for the introduction of virus particles into the cell.

The mechanism by which an organism detects changes in levels of extracellular calcium ions.

Interacting selectively with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

Interacting selectively with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.

A change in state or activity of an organism or cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the perception of an increase or decrease in the concentration of solutes outside the organism or cell.

Interacting selectively with collagen, a group of fibrous proteins of very high tensile strength that form the main component of connective tissue in animals. Collagen is highly enriched in glycine (some regions are 33% glycine) and proline, occurring predominantly as 3-hydroxyproline (about 20%).
