title: PSM2, a novel protein similar to MCAF2, is involved in the mouse embryonic and adult male gonad development.
abstract: By screening RIKEN database, we obtained a mouse ovary and uterus derived clone (RIKEN clone ID: 5031403I04). Multiple tissues expression analysis revealed that the clone was specifically expressed in ovary and to a higher extent in testis. It is expressed in early mouse embryo, especially in the embryonic gonad from 11.5 dpc (days post coitus). Furthermore, it is also expressed continuously from newborn testis to adult. Using testis sections in situ hybridization, we found the mRNA was localized to spermatogonia, round spermatids and mainly to spermatocytes. We cloned the cDNA from mouse testis. The gene consists of 10 exons spanning approximately 48 kb on mouse chromosome 16. The cDNA encodes a putative nuclear protein of 319 amino acids containing a coiled-coil motif. The deduced protein has high similarity with human MCAF2 (MBD1-containing chromatin-associated factor 2), so we termed it as PSM2 (protein similar to MCAF2) in this article. We therefore hypothesized that PSM2 might interact with some important partners by the conserved domain and be involved in the transcription modulation during gonad development.
