该基因编码p53家族转录因子的一个成员，参与细胞对应激和发育的反应。它定位于1p36染色体上的一个区域，该区域在神经母细胞瘤和其他肿瘤中经常被删除，并被认为包含多个肿瘤抑制基因该基因是单等位基因表达（可能来自母体等位基因）的证明支持了它是神经母细胞瘤候选基因的观点。由于选择性剪接和/或使用选择性启动子而产生的许多转录变体已经被发现用于该基因，但是一些变体的生物学有效性和全长性质尚未确定。[由RefSeq提供，2011年2月]
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.
