Methylthioadenosine phosphorylase, a gene frequently codeleted with p16(cdkN2a/ARF), acts as a tumor suppressor in a breast cancer cell line.


The human methylthioadenosine phosphorylase (MTAP) gene is located on 9p21 and is frequently homozygously deleted, along with p16(cdkN2a/ARF), in a wide variety of human tumors and human tumor-derived cell lines. The function of MTAP is to salvage methylthioadenosine, which is produced as a byproduct of polyamine metabolism. We have reintroduced MTAP into… (More)
