Cancer tissues showed moderate to strong nuclear positivity with additional cytoplasmic positivity in a few cases. Several cases of lymphomas, renal, liver and stomach cancers were weakly stained or negative.
Cancer tissues showed moderate nuclear and granular cytoplasmic staining. A single case each of duct carcinoma of breast, squamous cell carcinoma of head and neck, glioma and embryonal carcinoma of testis exhibited strong positivity.
This gene encodes a nucleic acid-binding protein that plays a role in a variety of nuclear processes, including pre-mRNA splicing and transcriptional regulation. The encoded protein forms a complex with the far upstream DNA element (FUSE) and FUSE-binding protein at the myelocytomatosis oncogene (MYC) promoter. This complex represses MYC transcription through the core-TFIIH basal transcription factor. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
