|WB||1/1000. Predicted molecular weight: 42-44 kDa.|
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.
modificationsDually phosphorylated on Thr-185 and Tyr-187, which activates the enzyme. Dephosphorylated by PTPRJ at Tyr-187.

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.
ab17942 staining ERK1 + ERK2 in Embryonic Stem Cell-induced Mouse Neurospheres by Immunohistochemistry (Frozen sections). 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.
ab17942 staining ERK1 + ERK2 in Human stomach tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). 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.
ab17942 staining ERK1 + ERK2 in NIH3T3 Mouse Fibroblasts cell line by ICC/IF (Immunocytochemistry/immunofluorescence). 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 analysis of Mice retinas (40-50μg/lane) labelling with anti-ERK1/2 at 1:300 (ab17942) and mouse monoclonal anti-phosphorylated ERK1/2 at 1:300 (ab50011), in 5% nonfat milk in TBST overnight at 4ºC. HRP conjugated antibodies were used as the secondary antibodies.
Data is expressed as percentage change in phosphorylated ERK1/2 (p-ERK1/2) over total ERK1/2 (t-ERK1/2) calculated in control and diabetic mice maintained with and without Edaravone treatment
Results are expressed as mean±SD. Values obtained from Normal group are considered as 100%. *P<0.05, ***P<0.001 vs. Normal, #P<0.05 vs. Edaravone
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.
