Protein attributes

Sequence length	152 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes.
Subunit structure	Monomer.
Subcellular location	Secreted.
Tissue specificity	Activated T-cells, mast cells, natural killer cells.
Sequence similarities	Belongs to the IL-3 family.
