1 Expression Analysis of the Mouse multi-copy X-linked gene Xlr-related, meiosis-regulated

(Xmr), reveals that Xmr encodes a spermatid-expressed cytoplasmic protein, SLX/XMR1 Short title: Spermatid-specific expression of mouse Xmr Summary sentence: Previous work concluded that Xmr/Slx encodes a meiotically expressed nuclear protein with a putative role in the meiotic silencing of the X and Y; here we show that the XMR/SLX protein is in fact a spermatid-specific cytoplasmic protein
