Several skin cancers along with squamous cell carcinomas of head and neck showed moderate to strong nuclear positivity. Several cervical and a few urothelial cancers and exhibited weak to moderate immunoreactivity. Other cancer tissues were negative.
Moderate to strong nuclear positivity was observed in basal cell carcinomas and few squamous cell carcinomas. Remaining cancer tissues were negative.

Entrez gene summary
This gene encodes a member of the p53 family of transcription factors involved in cellular responses to stress and development. It maps to a region on chromosome 1p36 that is frequently deleted in neuroblastoma and other tumors, and thought to contain multiple tumor suppressor genes. The demonstration that this gene is monoallelically expressed (likely from the maternal allele), supports the notion that it is a candidate gene for neuroblastoma. Many transcript variants resulting from alternative splicing and/or use of alternate promoters have been found for this gene, but the biological validity and the full-length nature of some variants have not been determined.
