功能
Stimulates transcription. Binds to purine-rich DNA sequences. Can form a ternary complex with the serum response factor and the ETS and SRF motifs of the fos serum response element. -
组织特异性
Lung and testis. -
序列相似性
Belongs to the ETS family.
Contains 1 ETS DNA-binding domain. -
翻译后修饰
Sumoylation represses transcriptional activator activity as it results in recruitment of HDAC2 to target gene promoters which leads to decreased histone acetylation and reduced transactivator activity. It also regulates nuclear retention.
On mitogenic stimulation, phosphorylated on C-terminal serine and threonine residues by MAPK1. Ser-383 and Ser-389 are the preferred sites for MAPK1. In vitro, phosphorylation by MAPK1 potentiates ternary complex formation with the serum responses factors, SRE and SRF. Phosphorylation leads to loss of sumoylation and restores transcriptional activator activity. -

All lanes : Anti-ELK1 antibody [EPR1913(2)] (ab188316) at 1/1000 dilution
Lane 1 : Wild-type HeLa cell lysate
Lane 2 : ELK1 knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 45 kDa
Observed band size: 55 kDa why is the actual band size different from the predicted?Lanes 1- 2: Merged signal (red and green). Green - ab188316 observed at 55 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.
ab188316 was shown to react with ELK1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab261764 (knockout cell lysate ab256904) was used. Wild-type HeLa and ELK1 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab188316 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: ELK1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa positve whole cell lysate (20 µg)
Lane 4: MCF7 negative whole cell lysate (20 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab188316 observed at 55 kDa. Red - loading control, ab18058, observed at 130 kDa.
ab188316 was shown to specifically react with ELK1 in wild-type HAP1 cells as signal was lost in ELK1 knockout cells. Wild-type and ELK1 knockout samples were subjected to SDS-PAGE. Ab188316 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 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.
