Bis(5'-Adenosyl)-Triphosphatase (FHIT) Antibody – Rabbit Polyclonal

This gene, a member of the histidine triad gene family, encodes a diadenosine 5',5'''-P1,P3-triphosphate hydrolase involved in purine metabolism. The gene encompasses the common fragile site FRA3B on chromosome 3, where carcinogen-induced damage can lead to translocations and aberrant transcripts of this gene. In fact, aberrant transcripts from this gene have been found in about half of all esophageal, stomach, and colon carcinomas. Alternatively spliced transcript variants have been found for this gene.

FHIT: a member of the histidine triad gene family. A diadenosine 5',5'''-P1,P3-triphosphate hydrolase involved in purine metabolism. Its gene encompasses the common fragile site FRA3B on chromosome 3, where carcinogen-induced damage can lead to translocations and aberrant transcripts of this gene. A possible tumor suppressor in specific tissues. Phospho-FHIT observed in liver and kidney, but not in brain and lung. Phospho-FHIT undetected in all tested human tumor cell lines. Aberrant transcripts from this gene have been found in about half of all esophageal, stomach, and colon carcinomas.
