title: Human CSF-1: gene structure and alternative splicing of mRNA precursors.
abstract: Bone marrow progenitor cells differentiate into mononuclear phagocytes in the presence of colony stimulating factor-1 (CSF-1). Characterization of the human CSF-1 gene shows that it contains 10 exons and 9 introns, which span 20 kb. Analysis of multiple CSF-1 transcripts demonstrates that alternate use of exon 6 splice acceptor sites and 3' noncoding sequence exons occurs. These alternatively spliced transcripts can encode either a 224 or a 522 amino acid CSF-1. Implications of differential splicing for the production and function of CSF-1 are discussed.
