Catalysis of the reaction: homocysteine + betaine = L-methionine + dimethylglycine.

The breakdown into simpler components of phenylalanine, 2-amino-3-phenylpropanoic acid.

Interacting selectively with a death receptor.

Functions to control the survival, growth, differentiation and effector function of tissues and cells.

hematopoietin/interferon-class (D200-domain) cytokine receptor binding

hematopoietin/interferon-class (D200-domain) cytokine receptor ligand

Interacting selectively with the erythropoietin receptor.

Golgi to plasma membrane protein transport

The directed movement of proteins from the Golgi to the plasma membrane in transport vesicles that move from the trans-Golgi network to the plasma membrane.

granulocyte macrophage colony-stimulating factor receptor binding

Interacting selectively with the granulocyte macrophage colony-stimulating factor receptor.

The chemical reactions involving melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.
