Western blot analysis of extracts from various cell lines using ELL (D7N6U) Rabbit mAb.
Immunoprecipitation of ELL from 293T cell extracts using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or ELL (D7N6U) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using ELL (D7N6U) Rabbit mAb.
Confocal immunofluorescent analysis of HeLa cells using ELL (D7N6U) Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red).
Chromatin immunoprecipitations were performed with cross-linked chromatin from 293T cells and ELL (D7N6U) Rabbit mAb, using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. DNA Libraries were prepared using SimpleChIP® ChIP-seq DNA Library Prep Kit for Illumina® #56795. The figure shows binding across SSR2 gene. For additional ChIP-seq tracks, please download the product data sheet.
Chromatin immunoprecipitations were performed with cross-linked chromatin from 293T cells and either ELL (D7N6U) Rabbit mAb or Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human RNU2-1 Promoter Primers #14084 and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
The super elongation complex (SEC) plays a critical role in regulating RNA polymerase II (RNAPII) transcription elongation (1). 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 (MLL) 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 in vitro, (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 MLL with the members of the SEC leads to SEC recruitment to MLL regulated genes, such as the highly developmentally regulated Hox genes, implicating the misregulation and overexpression of these genes as underlying contributors to leukemogenesis (1,2,9,11).
