Target
-
FunctionInvolved in both the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors such as ELK1. Phosphorylates EIF4EBP1; required for initiation of translation. Phosphorylates microtubule-associated protein 2 (MAP2). Phosphorylates SPZ1 (By similarity). Phosphorylates heat shock factor protein 4 (HSF4) and ARHGEF2.
Acts as a transcriptional repressor. Binds to a [GC]AAA[GC] consensus sequence. Repress the expression of interferon gamma-induced genes. Seems to bind to the promoter of CCL5, DMP1, IFIH1, IFITM1, IRF7, IRF9, LAMP3, OAS1, OAS2, OAS3 and STAT1. Transcriptional activity is independent of kinase activity. -
Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
Contains 1 protein kinase domain. -
DomainThe TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
-
Post-translational
modificationsDually phosphorylated on Thr-185 and Tyr-187, which activates the enzyme. Dephosphorylated by PTPRJ at Tyr-187. -
Cellular localizationNucleus.

All lanes : HRP conjugated goat anti-rabbit antibody at 1/3000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 42-44 kDa
Observed band size: 42,44 kDa why is the actual band size different from the predicted?
Exposure time: 5 minutes
The tissue was harvested seven days post surgery, sonicated with RIPA buffer and the protein estimate made by Lowry. A 10% SDS-PAGE gel was run for 1.5 hr at 100V and transfered to PVDF membrane for 1.5 hr at 274 mA. The blot was blocked with 5% BSA for 1 hour at 23°C. The primary antibody was incubated with the blot for 18 hours at 4°C. -

Sections were formaldehyde-fixed prior to blocking in 10% serum for 30 minutes at room temperature. The primary antibody was diluted 1/1000 and incubated with the sample for 12 hours at 4°C. An Alexa Fluor® 594-conjugated Goat anti-Rabbit polyclonal antibody, diluted 1/1500 was used as the secondary.

Tissue was fixed with formaldehyde and blocked with 5% serum for 1 hour at 23°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/200 in blocking buffer) for 1 hourat 23°C. A HRP-conjugated GOat anti-rabbit IgG polyclonal was used as the secondary antibody.

Cells were fixed with PFA, permeabilized with 0.025% Triton-X in TBS and blocked with 5% serum for 1 hour at 23°C. Samples were incubated with primary antibody (1/200 in blocking buffer) for 16 hours at 4°C. An Alexa Fluor® 568-conjugated Goat anti-rabbit IgG polyclonal diluted to 1/1000 was used as the secondary antibody.

Western blot - Anti-ERK1 + ERK2 antibody (ab17942)Western Blot for ab17942.
Extracts prepared from PC12 cells not stimulated (-), or stimulated with NGF (+) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to nitrocellulose. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4C, then were incubated with ERK1&2 pan antibody for two hours at room temperature in a 3% BSA-TBST buffer. After washing, membranes were incubated
with goat anti-rabbit IgG alkaline phosphatase.These data show that ab17942 ERK1&2 antibody allows the total amount of ERK1&2 to be measured.
