該基因編碼一種參與轉錄和轉錄后控制途徑的腫瘤抑制因子。該蛋白是paf蛋白復合物的一個組成部分，它與rna聚合酶ii亞單位polr2a和組蛋白甲基轉移酶復合物相關。這種蛋白質似乎有助于3’mrna處理因子與主動轉錄的染色質的關聯。該基因突變與甲狀旁腺功能亢進癥、頜骨腫瘤綜合征、家族性孤立性甲狀旁腺功能亢進癥和甲狀旁腺癌有關。[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]
