A change in state or activity of an organism (in terms of movement, secretion, gene expression, enzyme production, etc.) in response to temperatures below the optimal temperature for that organism.

Catalysis of the reaction: protein serine/threonine phosphate + H2O = protein serine/threonine + phosphate.

transforming growth factor beta receptor, cytoplasmic mediator activity

TGFbeta receptor, cytoplasmic mediator activity

Activity of any of the molecules that transmit the signal from a TGFbeta receptor through the cytoplasm to the nucleus.

calcium-dependent protein serine/threonine phosphatase activity

magnesium-dependent protein serine/threonine phosphatase activity

Catalysis of the removal of a serine- or threonine-bound phosphate group from a protein; action dependent on magnesium.

Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

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

non-membrane spanning protein tyrosine phosphatase activity

Enables the directed movement of carnitine into, out of, within or between cells. Carnitine is a compound that participates in the transfer of acyl groups across the inner mitochondrial membrane.

receptor signaling protein serine/threonine kinase signaling protein activity

receptor signalling protein serine/threonine kinase signalling protein activity

prenylated protein tyrosine phosphatase activity

Enables the directed movement of acyl carnitine into, out of, within or between cells. Acyl carnitine is the condensation product of a carboxylic acid and carnitine and is the transport form for a fatty acid crossing the mitochondrial membrane.

Functions as a scaffold for the assembly of a multiprotein mitogen-activated protein kinase (MAPK) complex. MAPK scaffold proteins have binding sites for MAPK pathway kinases as well as for upstream signaling proteins.

oxidoreductase activity, acting on diphenols and related substances as donors, cytochrome as acceptor
