Few cases of squamous cell carcinoma of lung, head and neck and urothelial cancers displayed weak to moderate membranous positivity. Rare cases of squamous cell carcinoma of skin exhibited additional nucleolar positivity. Rare cases of pancreatic cancer and a single case each of breast, ovarian and adenocarcinoma of lung showed weak to moderate cytoplasmic staining. Remaining cancer tissue were negative.
GENE INFORMATION
Gene name

Description
Transglutaminase 1 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a membrane protein that catalyzes the addition of an alkyl group from an akylamine to a glutamine residue of a protein, forming an alkylglutamine in the protein. This protein alkylation leads to crosslinking of proteins and catenation of polyamines to proteins. This gene contains either one or two copies of a 22 nt repeat unit in its 3' UTR. Mutations in this gene have been associated with autosomal recessive lamellar ichthyosis (LI) and nonbullous congenital ichthyosiform erythroderma (NCIE). [provided by RefSeq, Jul 2008]
