Flow Cytometry (Intracellular) - Anti-eIF4EBP1 antibody [Y330] - BSA and Azide free (AB173322)

This data was developed using ab32130, the same antibody clone in a different buffer formulation.

Flow Cytometry analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling eIF4EBP1 with purified ab32130 at 1/1000 dilution (1 μg/mL) (Red). Cells were fixed with 4% Paraformaldehyde and permeabilised with 90% Methanol. A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) secondary antibody was used at 1/2000. Isotype control - Rabbit monoclonal IgG (Left).
Low expression in mitotic phase was consistent with literature. (PMID : 11553333)

This data was developed using the same antibody clone in a different buffer formulation (ab32130).

Lanes 1-2 : Merged signal (red and green). Green - ab32130 observed at 13 kDa. Red - loading control ab8245 observed at 37 kDa.

ab32130 Anti-eIF4EBP1 antibody [Y330] was shown to specifically react with eIF4EBP1 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264784 (knockout cell lysate ab257146) was used. Wild-type and eIF4EBP1 knockout samples were subjected to SDS-PAGE. ab32130 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 Dilution and 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.

Supplementary information

EIF4EBP1 also known as 4EBP1 or p4EBP1 is an important protein that acts as a translational repressor by binding to eIF4E therefore inhibiting cap-dependent translation. The molecular weight of 4EBP1 is approximately 12 kDa. This protein is ubiquitously expressed in various tissues indicating its widespread involvement in cellular functions. eIF4EBP1 can be detected and quantified using techniques like the eIF4EBP1 ELISA making it a common target in research for its role in translation regulation.
Biological function summary

EIF4EBP1 plays an important role in regulating cell growth and proliferation by modulating protein synthesis. It is a part of the eIF4F complex which is responsible for the initiation of mRNA translation. When hypophosphorylated eIF4EBP1 binds tightly to eIF4E and prevents the assembly of the active eIF4F complex leading to reduced translation initiation of mRNAs involved in growth and survival. This regulation is important in conditions where cells need to adapt to metabolic stress or external signals.

Pathways

The mammalian target of rapamycin (mTOR) pathway regulates eIF4EBP1 through phosphorylation. In response to growth signals mTOR phosphorylates eIF4EBP1 causing the release of eIF4E and allowing mRNA translation to proceed. This interaction links eIF4EBP1 to the PI3K/AKT/mTOR signaling pathway which influences cell cycle progression and survival. Related proteins in this pathway include ribosomal protein S6 kinase (S6K1) which is also phosphorylated by mTOR to promote protein synthesis.

Deregulation of eIF4EBP1 has been implicated in cancer and neurological disorders. In cancer hyperactive mTOR signaling can lead to excessive phosphorylation of 4EBP1 decreasing its ability to inhibit eIF4E and enhancing translation of oncogenic proteins. In neurological disorders imbalanced eIF4EBP1 activity can disrupt synaptic plasticity and memory formation. Proteins such as p70S6K which are also part of the mTOR pathway share connections with eIF4EBP1 in these pathological conditions.

Target data

Repressor of translation initiation that regulates EIF4E activity by preventing its assembly into the eIF4F complex : hypophosphorylated form competes with EIF4G1/EIF4G3 and strongly binds to EIF4E, leading to repress translation. In contrast, hyperphosphorylated form dissociates from EIF4E, allowing interaction between EIF4G1/EIF4G3 and EIF4E, leading to initiation of translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.
