1-138aa, full length protein. MW: 9,074 Da. Purity >85% (SDS-PAGE). This gene was identified in the neuroblastoma tumour suppressor candidate region on chromosome 1p36. It contains a TFIID-31 domain, similar to that found in TATA box-binding protein-associated factor, TAF(II)31, which is required for p53-mediated transcription activation. This gene was expressed at very low levels in neuroblastoma tumours, and was shown to reduce cell growth in neuroblastoma cells, suggesting that it may have a
