Lane 3 : BCL11A (Ctip1) knockout HAP1 whole cell lysate (20 μg)

Lanes 1 - 4 : Merged signal (red and green). Green - ab191401 observed at 91 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab191401 was shown to recognize BCL11A (Ctip1) in wild type cells as signal was lost at the expected MW in BCL11A (Ctip1) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and BCL11A (Ctip1) knockout samples were subjected to SDS-PAGE. ab191401 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Target data

Transcription factor (PubMed : 16704730, PubMed : 29606353). Associated with the BAF SWI/SNF chromatin remodeling complex (PubMed : 23644491, PubMed : 39607926). Binds to the 5'-TGACCA-3' sequence motif in regulatory regions of target genes, including a distal promoter of the HBG1 hemoglobin subunit gamma-1 gene (PubMed : 29606353, PubMed : 39423807). Involved in regulation of the developmental switch from gamma- to beta-globin, probably via direct repression of HBG1; hence indirectly repressing fetal hemoglobin (HbF) level (PubMed : 26375765, PubMed : 29606353, PubMed : 39423807, PubMed : 39607926). Involved in brain development (PubMed : 27453576). May play a role in hematopoiesis (By similarity). Essential factor in lymphopoiesis required for B-cell formation in fetal liver (By similarity). May function as a modulator of the transcriptional repression activity of NR2F2 (By similarity).
