Reference Data

• RefSeq: NP_757351
• Locus ID: 1435
• UniProt ID: P09603
• Cytogenetics: 1p13.3
• RefSeq Size: 2772
• RefSeq ORF: 1662
• Synonyms: CSF-1; MCSF
• Summary: The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of macrophages. The active form of the protein is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. The encoded protein may be involved in development of the placenta. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]
