The SEC is composed of AFF4, AFF1\/AF4, MLLT3\/AF9, and MLLT1\/ENL proteins. The pathogenesis of mixed lineage leukemia is often associated with translocations of the SEC subunits joined to the histone H3 Lys4 methyltransferase mixed lineage leukemia ( ) gene (1-4). The SEC has been found to contain RNAPII elongation factors eleven-nineteen lysine-rich leukemia (ELL), ELL2, and ELL3, along with the associated factors EAF1 and EAF2, which can increase the catalytic rate of RNAPII transcription , (1,2,5-7). The SEC positive transcription elongation factor b (P-TEFb) phosphorylates the carboxy-terminal domain within the largest subunit of RNAP II at Ser2 of the heptapeptide repeat. The SEC negative transcription elongation factors, DRB-induced stimulating factor (DSIF) and negative elongation factor (NELF), signal the transition from transcription initiation and pausing to productive transcription elongation (2,8-10). The chromosomal translocation of with the members of the SEC leads to SEC recruitment to MLL regulated genes, such as the highly developmentally regulated genes, implicating the misregulation and overexpression of these genes as underlying contributors to leukemogenesis (1,2,9,11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nC19orf17; DKFZp434I1916; Eleven-nineteen lysine-rich leukemia protein; ELL; ELL gene (11-19 lysine-rich leukemia gene); ELL\/KMT2A fusion protein; ELL1; elongation factor for RNA polymerase II; elongation factor RNA polymerase II; KMT2A\/ELL fusion protein; MEN; PPP1R68; protein phosphatase 1, regulatory subunit 68; RNA polymerase II elongation factor ELL\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 70\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797609730217,"sku":"14468T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-14468t","provider":"Iright","version":"1.0","type":"link"}
