Any series of molecular signals that conveys information from the endoplasmic reticulum to the nucleus, usually resulting in a change in transcriptional regulation.

The chemical reactions involving any one of a family of organic molecules consisting of a pyrimidine base covalently bonded to a sugar deoxyribose (a deoxyribonucleoside).

regulation of mitogen-activated protein kinase activity

Any process that modulates the frequency, rate or extent of MAP kinase activity.

positive regulation of mitogen-activated protein kinase activity

Any process that activates or increases the rate of protein kinase activity.

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.

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).

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

The directed movement of viral proteins within the host cell.

The formation from simpler components of any purine 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.
