Catalysis of the reaction: GTP + protein = diphosphate + guanylyl-protein; mediates the addition of an guanylyl (guanosine 5'-monophosphate; GMP group) to specific residues of target proteins.

Catalysis of the transfer of a guanylyl group to an acceptor.

The anaerobic chemical reactions and pathways resulting in the breakdown of L-alanine, yielding energy in the form of ATP.

The anaerobic chemical reactions and pathways resulting in the breakdown of amino acids; in these reactions, one amino acid is oxidised (acts as an electron donor) and a different amino acid is reduced (acts as an electron acceptor); oxidation of the electron-donating amino acid yields energy in the form of ATP.

The anaerobic chemical reactions and pathways resulting in the breakdown of glycine, yielding energy in the form of ATP.

Combining with a neurotrophin, any of a family of growth factors that prevent apoptosis in neurons and promote nerve growth, and transmitting the signal to initiate a change in cell activity.

Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.

Combining with tumor necrosis factor, a proinflammatory cytokine produced by monocytes and macrophages, to initiate a change in cell function.

Combining with an extracellular messenger (called a death ligand), and transmitting the signal from one side of the plasma membrane to the other to initiate apoptotic or necrotic cell death.

Sensing extracellular osmolarity to initiate a change in cell activity, and spanning the membrane of the cell.
