Deleted In Bladder Cancer 1 (DBC1)

Deleted in bladder cancer protein 1 is a protein encoded by the DBC1 gene.This gene is located within chromosome 9 (9q32-33), a chromosomal region that frequently shows loss of heterozygosity in transitional cell carcinoma of the bladder. It contains a 5""" CpG island that may be a frequent target of hypermethylation, and it may undergo hypermethylation-based silencing in some bladder cancers. The functions of this gene are unknown, and it has not yet been placed in a protein family or functional pathway. Nonetheless, it is suspected to act as a tumor supressor gene.Inhibits cell proliferation by negative regulation of the G1/S transition. Mediates cell death which is not of the classical apoptotic type and regulates expression of components of the plasminogen pathway.
