- * Granulocyte-macrophage colony-stimulating factor signature *
- **************************************************************
-
- Granulocyte-macrophage colony-stimulating factor (GM-CSF) [1,2] is a cytokine
- that acts in hematopoiesis by stimulating the growth and differentiation of
- hematopoietic precursor cells from various lineages, including granulocytes,
- macrophages, eosinophils and erythrocytes.
-
- GM-CSF is a glycoprotein of about 120 amino acid residues that contains four
- conserved cysteine residues involved in two disulfide bonds, as shown in the
- following schematic representation.

-
- 'C': conserved cysteine involved in a disulfide bond.
- '*': position of the pattern.
-
- As a signature pattern, we selected the region that includes the second and
- third conserved cysteines.
-
- -Consensus pattern: C-P-P-T-x-E-T-x-C
- [The two C's are involved in disulfide bonds]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: October 1993 / Pattern and text revised.
