Isolation and Characterization of the Mouse Homolog of SYT, a Gene Implicated in the Development of Human Synovial Sarcomas

Oncogene. 1996 Aug 1;13(3):643-8.

Abstract

In a previous study we reported the isolation of the human synovial sarcoma-associated t(X;18) breakpoint. As a result of this translocation, the SYT gene on chromosome 18 fuses to either the SSX1 or the SSX2 gene on the X chromosome, depending on the exact location of the breakpoint within band Xp11.2. As yet, little is known about the modes of action of the SYT and SSX genes and their respective (fusion) products. Here we report the isolation of the mouse homolog of SYT, its full length cDNA sequence, its chromosomal localization, and its spatio-temporal expression patterns in adult and embryonic tissues. The SYT gene was found to be well conserved during evolution and is part of a region of synteny between the human and mouse chromosomes 18. In early embryogenesis, Syt is ubiquitously expressed. In later stages, the expression becomes confined to cartilage tissues, specific neuronal cells and some epithelial derived tissues. In mature testis, expression was specifically observed in primary spermatocytes.
