NSD3（nuclear receptor binding SET domain protein 3），癌症关联基因，基因ID：54904，该基因与wolf-hirschhorn综合征候选基因1相关，编码一个具有pwp（脯氨酸-色氨酸-色氨酸-脯氨酸）结构域的蛋白质。该蛋白在赖氨酸残基4和27处甲基化组蛋白H3，抑制基因转录。已经描述了两种可选的拼接变体。[由RefSeq提供，2015年5月]This gene is related to the Wolf-Hirschhorn syndrome candidate-1 gene and encodes a protein with PWWP (proline-tryptophan-tryptophan-proline) domains. This protein methylates histone H3 at lysine residues 4 and 27， which represses gene transcription. Two alternatively spliced variants have been described. [provided by RefSeq， May 2015]。
