A novel cyclin gene (CCNF) in the region of the polycystic kidney disease gene (PKD1).

The major locus for autosomal dominant polycystic kidney disease (PKD1) is located in a gene-rich region on chromosome 16p13.3. Recently the identification of the gene responsible for PKD1 has been described. While searching for candidate genes in this region, we isolated a new member of the cyclin family. We have characterized the transcript by sequencing, determination of the exon intron boundaries, and Northern blot analysis. Cyclin F is related to A- and B-type cyclins by sequence, but its function is unknown.
