The multi-copy mouse gene Sycp3-like Y-linked (Sly) encodes an abundant spermatid protein that interacts with a histone acetyltransferase and an acrosomal protein.

ABSTRACT: Deletion analysis has established that genes on the Y chromosome are essential for normal sperm production in humans, mice, and Drosophila. In mice, long-arm deletions have an impact on spermiogenesis, with the most extensive deletions resulting in severe sperm head malformations and infertility. Intriguingly, smaller deletions are compatible with fertility but result in a distorted sex ratio in favor of females, and recently it was found that Y long-arm deletions are also associated with a marked upregulation of several X-encoded and Y-encoded spermatid-expressed genes. The mouse Y long arm encodes a number of distinct transcripts, each of which derives from multiple gene copies. Of these multicopy genes, the recently described Sly has been favored as the gene underlying the spermiogenic
