A protein of the YTH family has been shown to selectively remove transcripts of meiosis-specific genes expressed in mitotic cells [3]. It has been speculated that in higher eukaryotic YTH-family members may be involved in similar mechanisms to suppress gene regulation during gametogenesis or general silencing. The rat protein Swiss:Q9QY02 YT521-B is a tyrosine-phosphorylated nuclear protein, that interacts with the nuclear transcriptosomal component scaffold attachment factor B, and the 68-kDa Src substrate associated during mitosis, Sam68. In vivo splicing assays demonstrated that YT521-B modulates alternative splice site selection in a concentration-dependent manner [1]. The YTH domain has been identified as part of the PUA superfamily [4].	Domain
