Catalysis of the reaction: NAD(P)+ + androsterone = NAD(P)H + H+ + 5-alpha-androstane-3,17-dione. The reaction is A-specific (i.e. the pro-R hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD(P)+.

Catalysis of the reaction: NAD(P)+ + androsterone = NAD(P)H + H+ + 5-alpha-androstane-3,17-dione.

Catalysis of the reaction: NADP+ + (R)-3-(4-hydroxyphenyl)lactate = NADPH + H+ + 3-(4-hydroxyphenyl)pyruvate.

Catalysis of the reaction: NADP+ + 6-lactoyl-5,6,7,8-tetrahydropterin = NADPH + H+ + 6-pyruvoyltetrahydropterin.

The positive regulation of a signal transduction pathway in response to a stimulus upon prolonged exposure to that stimulus.

OBSOLETE. The steps whereby the downstream processes started by a signal are brought to a conclusion. Examples include destruction of cAMP by PDE, or endocytosis resulting from receptor phosphorylation. The termination process ends when the receptor has returned to its inactive state.

OBSOLETE. The process in which a stretch signal causes activation of a receptor.

Catalysis of the reaction: NADP(+) + prostaglandin E(1) = 15-dehydro-prostaglandin E1 + H(+) + NADPH.

OBSOLETE. The process in which a mechanical signal causes activation of a receptor.

Catalysis of the reaction: NADP+ + (5Z,13E)-(15S)-9-alpha,15-dihydroxy-11-oxoprosta-5,13-dienoate = NADPH + H+ + (5Z,13E)-9-alpha-hydroxy-11,15-dioxoprosta-5,13-dienoate.

Catalysis of the reaction: NADP+ + a 7-beta-hydroxysteroid = NADPH + H+ + a 7-oxosteroid.

Any process that modulates the frequency, rate or extent of ripoptosome assembly involved in a necroptotic process.

A process in which a protein is transported to, or maintained in, a location within a meiotic spindle pole body.

Binding to riboflavin.

Any process that stops, prevents or reduces the frequency, rate or extent of ripoptosome assembly involved in a necroptotic process.

Any process that modulates the frequency, rate or extent of shade avoidance.

Any regulation of mitochondrial membrane permeability that is involved in programmed necrotic cell death.

Any process that activates or increases the frequency, rate or extent of shade avoidance.

Any process that stops, prevents or reduces the frequency, rate or extent of shade avoidance.
