title: Genomic structure of SAS, a member of the transmembrane 4 superfamily amplified in human sarcomas.
abstract: SAS is a recently identified member of the transmembrane 4 superfamily (TM4SF) that is frequently amplified in human sarcomas. To further its characterization and to confirm its classification, the genomic structure of the SAS gene was determined. The SAS gene covers approximately 3.2 kb of DNA. It contains six exons within its translated region, three of which are highly conserved in the TM4SF. 5' to the translation start site are two putative transcription start sites, two CCAAT consensus sequences, and potential binding sites for both Sp1 and ATF transcription factors. Comparison of SAS organization to human ME491, CD9, and CD53 and murine CD53 and TAPA-1 confirms that SAS is a member of this family of genes and is consistent with the theory that these genes arose through duplication and divergent evolution.
