== Disease ==
[[http://www.uniprot.org/uniprot/FHIT_HUMAN FHIT_HUMAN]] Note=A chromosomal aberration involving FHIT has been found in a lymphoblastoid cell line established from a family with renal cell carcinoma and thyroid carcinoma. Translocation t(3;8)(p14.2;q24.1) with RNF139. Although the 3p14.2 breakpoint has been shown to interrupt FHIT in its 5-prime non-coding region, it is unlikely that FHIT is causally related to renal or other malignancies.<ref>PMID:15007172</ref>   Note=Associated with digestive tract cancers. Numerous tumor types are found to have aberrant forms of FHIT protein due to deletions in a coding region of chromosome 3p14.2 including the fragile site locus FRA3B.<ref>PMID:15007172</ref>

== Publication Abstract from PubMed ==
The histidine triad (HIT) protein family is among the most ubiquitous and highly conserved in nature, but a biological activity has not yet been identified for any member of the HIT family. Fragile histidine triad protein (FHIT) and protein kinase C interacting protein (PKCI) were used in a structure-based approach to elucidate characteristics of in vivo ligands and reactions. Crystallographic structures of apo, substrate analog, pentacovalent transition-state analog, and product states of both enzymes reveal a catalytic mechanism and define substrate characteristics required for catalysis, thus unifying the HIT family as nucleotidyl hydrolases, transferases, or both. The approach described here may be useful in identifying structure-function relations between protein families identified through genomics.

Structure-based analysis of catalysis and substrate definition in the HIT protein family.,Lima CD, Klein MG, Hendrickson WA Science. 1997 Oct 10;278(5336):286-90. PMID:9323207<ref>PMID:9323207</ref>
