Mouse Histone-lysine N-methyltransferase PRDM9 (PRDM9) ELISA Kit

The PR domain is a protein-protein interaction module of about 100 amino acids. PR domain-containing proteins, such as PRDM9, are often involved in transcriptional regulation. The deduced 862-amino acid Meisetz protein contains a PR/SET domain in its N-terminal portion and a zinc finger domain containing multiple C2H2-type zinc fingers in its C-terminal portion. Hayashi et al. (2005) also cloned 2 Meisetz splice variants that encode shorter isoforms lacking the zinc finger domain. The PR/SET domain of Meisetz is highly conserved in human PRDM9. In situ hybridization, RT-PCR, and Northern blot analysis showed that mouse Meisetz transcripts were only expressed in germ cells entering meiotic prophase in female fetal gonads and in postnatal testis.
