Western blot - Human FOXO3 (FOXO3A) knockout HEK-293T cell lysate (AB256922)

This data was developed using the same antibody clone in a different buffer formulation (ab109629).

Lanes 1 - 4 : Merged signal (red and green). Green - ab109629 observed at 82 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37 kDa.

ab109629 was shown to react with FOXO3A in wild-type cells in Western blot with loss of signal observed in FOXO3 knockout cellS. Wild-type and FOXO3 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween®) before incubation with ab109629 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4 °C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated 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 in 20000 dilution for 1 h at room temperature before imaging.

Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.

Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

FOXO3A also known as FOXO3 or 1e2 is a transcription factor with a molecular weight of approximately 71 kDa. It belongs to the Forkhead box O family of proteins. This protein plays an important role in the regulation of transcription in response to oxidative stress and growth stimuli. FOXO3A is expressed in a variety of tissues including liver muscle and brain where it contributes to a wide range of cellular processes related to stress resistance and metabolism. Scientists frequently study FOXO3A using techniques like FOXO3A ELISA and apply FOXO3A anticuerpos in research to understand its function more intricately.
Biological function summary

FOXO3A acts as a regulator of genes involved in cell cycle arrest apoptosis and DNA repair. It is not part of a simple protein complex but works closely with multiple factors to influence cellular homeostasis. Significantly FOXO3A controls the expression of Bcl-2 a protein important for cell survival and the protein p27 which is important for cell cycle control. FOXO3A's activity modulates cellular longevity and impacts stress responses highlighting its abundant biological functions.

Pathways

FOXO3A integrates into the PI3K/AKT and the insulin signaling pathways both essential for cellular metabolism and proliferation control. In the PI3K/AKT pathway FOXO3A functionally links with proteins such as AKT and PTEN where its activity can be inhibited by AKT-mediated phosphorylation. In doing so it supports a balance between cell survival and apoptosis allowing the cell to adjust to growth conditions and external stressors effectively.

FOXO3A is linked to cancer and neurodegenerative diseases. In cancer alterations in FOXO3A activity or expression can affect tumor growth and resistance to oxidative stress often involving interactions with proteins like MDM2. Similarly in neurodegenerative disorders such as Alzheimer's disease FOXO3A modifies responses to oxidative damage potentially tied to proteins like Tau. Both instances highlight the role of FOXO3A as a versatile modulator that can influence the progression and management of various diseases.
