Enables the directed movement of polyamines, organic compounds containing two or more amino groups, into, out of, within or between cells.

Enables the directed movement of urea into, out of, within or between cells. Urea is the water soluble compound H2N-CO-NH2, produced in the liver via the ornithine-urea cycle. It is the main nitrogen-containing (urinary) excretion product in ureotelic animals.

perception of pain, sensory transduction of temperature

perception of pain, sensory detection of temperature

The series of events during the perception of pain in which a sensory temperature stimulus is received and converted into a molecular signal.

Catalysis of the phosphorylation and activation of members of the JUN family, a gene family that encodes nuclear transcription factors.

Enables the directed movement of a nucleobase, any nitrogenous base that is a constituent of a nucleoside, nucleotide, or nucleic acid, into, out of, within or between cells.

perception of pain, sensory transduction of mechanical stimulus

perception of pain, sensory detection of mechanical stimulus

The series of events during the perception of pain in which a sensory mechanical stimulus is received and converted into a molecular signal.

Catalysis of the phosphorylation of proteins. Mitogen-activated protein kinase; a family of protein kinases that perform a crucial step in relaying signals from the plasma membrane to the nucleus. They are activated by a wide range of proliferation- or differentiation-inducing signals; activation is strong with agonists such as polypeptide growth factors and tumor-promoting phorbol esters, but weak (in most cell backgrounds) by stress stimuli.

perception of pain, sensory transduction of chemical stimulus

perception of pain, sensory detection of chemical stimulus

The series of events during the perception of pain in which a sensory chemical stimulus is received and converted into a molecular signal.

The process of coupling lysine to lysyl-tRNA, catalyzed by lysyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.
