| abstractText | Mammalian Polycomb group (PcG) proteins are known to function during the maintenance of spatially restricted expression of Hox cluster genes and cellular proliferation. To understand the molecular basis of PcG functions, it is important to identify the components of mammalian PcG complexes. We isolated mouse YAF2 as a protein that interacts with Ring1B, a known constituent of mammalian PcG complexes. We show that the murine YAF2 locus generates two different transcripts, mYAF2-a and mYAF2-b by alternative splicing of the third exons which encode two YAF2 isoforms of 179 and conceptual 60 amino acids, respectively. At least five exons encoding mYAF2 transcripts are mapped on chromosome 15E3 region. Expression of mYAF2 mRNA was observed in both pre- and postimplantation embryos. In mid-gestation embryos, mYAF2 expression is strongly seen in the region close to the surface ectoderm. Finally, biochemical evidence and colocalization studies in tissue culture cells suggest that the product of the mYAF2 gene is involved in PcG complexes together with Ring1B and/or Ring1A. |
