CDC73（cell division cycle 73），癌症关联基因，基因ID：79577，该基因编码一种参与转录和转录后控制途径的肿瘤抑制因子。该蛋白是paf蛋白复合物的一个组成部分，它与rna聚合酶ii亚单位polr2a和组蛋白甲基转移酶复合物相关。这种蛋白质似乎有助于3’mrna处理因子与主动转录的染色质的关联。该基因突变与甲状旁腺功能亢进症、颌骨肿瘤综合征、家族性孤立性甲状旁腺功能亢进症和甲状旁腺癌有关。[由RefSeq提供，2009年7月]This gene encodes a tumor suppressor that is involved in transcriptional and post-transcriptional control pathways. The protein is a component of the the PAF protein complex， which associates with the RNA polymerase II subunit POLR2A and with a histone methyltransferase complex. This protein appears to facilitate the association of 3' mRNA processing factors with actively-transcribed chromatin. Mutations in this gene have been linked to hyperparathyroidism-jaw tumor syndrome， familial isolated hyperparathyroidism， and parathyroid carcinoma. [provided by RefSeq， Jul 2009]。
