Most cancer cells exhibited moderate cytoplasmic immunoreactivity. Papillary adenocarcinomas of the thyroid and several cases of colorectal, prostate, liver and pancreatic cancer showed strong cytoplasmic positivity. Glioma and most lymphoma cases were weakly stained or negative.
GENE INFORMATION
Gene name
ABCA5 (HGNC Symbol)
Synonyms
EST90625
Description
ATP-binding cassette, sub-family A (ABC1), member 5 (HGNC Symbol)
Entrez gene summary
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This encoded protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. This gene is clustered among 4 other ABC1 family members on 17q24, but neither the substrate nor the function of this gene is known. Alternative splicing of this gene results in several transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]
