生物學功能
SET-domain histone lysine methyltransferase, maybe acting as a nucleus-localized, basic transcriptional factor and also as a bifunctional transcriptional regulator
可能參與染色體11p15區域的印跡過程(指基因或染色體保留其配子的某些特徵並進行選擇性差異表達 )
組蛋白甲基化轉移酶活性: H3-K36雙甲基化作用
may be functioning as a bifunctional transcriptional regulator activating or repressing transcription in response to ligand binding
involved in the regulation of gene expression through stimulating the transition of RNA polymerase II from an initiation to fully elongation-competent state
在維持染色質的完整性至關重要
疾病與診斷
疾病
1,索托斯綜合徵 caused by mutations in the NSD1 gene
2,兒童急性髓系白血病 極少數情況,NSD1的活性變化 A novel gene, NSD1, is fused to NUP98 in the t(5;11)(q35;p15.5) in de novo childhood acute myeloid leukemia 2001 98: 1264-1267 doi:10.1182/blood.V98.4.1264 第5號染色體的一部分脫落並重新掛接到11號染色體,從而導致NSD1基因活性被破壞。研究人員正在研究NUP98-NSD1基因與急性髓細胞白血病的發展的關係。
