Mammalian splicing factor 1 (designated SF1, zinc finger protein 162, ZFM1,CW17R and mammalian branch point binding protein [mBBP]) specificallyrecognizes the seven-nucleotide branch point sequence located at 3'' splicesites and participates in the assembly of early spliceosomal complexes.Splicing factor 1 functions as a transcriptional repressor and may control bothproliferation and expression of pro-inflammatory gene products in smoothmuscle cells. In addition, cytokine-induced downregulation of splicing factor 1 expression may contribute to the pathogenesis of hyperproliferative inflammatory diseases. The structure of splicing factor 1 contains a nuclear transport domain, a metal binding motif, and glutamine- and proline-rich regions.Human splicing factor 1 also exists as several different isoforms, H1-isoformand Bo-isoform, produced by alternative splicing events. The human splicingfactor 1 gene is located on chromosome 11 close to the gene encoding Menin,the gene responsible for multiple endocrine neoplasia-type 1 (MEN1).
