Western blot - Anti-Neurofibromin antibody [EPR22989-68] (AB238142)

Lanes 1-3 : Merged signal (red and green). Green - ab238142 observed at 319 kDa. Red - loading control ab7291 observed at 50 kDa.

ab238142 Recombinant Anti-NF1 antibody [EPR22989-68] was shown to specifically react with NFIB in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264725 (knockout cell lysate ab258533) was used. Wild-type and NF1 knockout samples were subjected to SDS-PAGE. ab238142 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) 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.

Anti-NF1 antibody [EPR22989-68] (ab238142) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab238142 was shown to bind specifically to NF1. A band was observed at 180-270 kDa in wild-type MCF7 cell lysates with no signal observed at this size in NF1 knockout cell line. To generate this image, wild-type and NF1 knockout MCF7 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

ab238142 was shown to specifically react with Neurofibromin in wild-type HAP1 cells as signal was lost in Neurofibromin knockout cells. Wild-type and Neurofibromin knockout samples were subjected to SDS-PAGE. ab238142 and ab129002 (Rabbit anti-Vinculin loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/5000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument using the ECL technique. Lysate should be made freshly and used in WB immediately to minimize protein degradation. Degraded fragment(250 KD) observed is consistent with what has been described in the literature (PMID : 30131853, PMID : 30408279).

Supplementary information

Neurofibromin is a protein that functions as a Ras GTPase-activating protein acting to promote the hydrolysis of Ras-bound GTP to GDP which inactivates Ras signaling. This regulatory function involves the suppression of excessive cell proliferation and differentiation. Alternate names for neurofibromin include NF1 or neurofibromin 1. The mass of neurofibromin is approximately 327 kDa. Neurofibromin is expressed widely across various tissues with notable expression in the nervous system and the brain.
Biological function summary

Neurofibromin regulates pathways involved in cell growth and development. It does not form part of a large multiprotein complex but interacts with microtubules and other signaling proteins to carry out its regulatory functions. Neurofibromin primarily affects pathways that manage cell cycle progression and it plays a critical role in inhibiting uncontrolled cell growth ensuring proper cellular homeostasis.

Pathways

Neurofibromin fits into the Ras-MAPK pathway where it controls the activity of Ras an important regulatory protein involved in signal transduction related to cell division and differentiation. Neurofibromin's action on Ras directly impacts the activation of the MAPK pathway which is important in mediating cellular responses to growth signals. This protein also interacts functionally with proteins like SOS1 another regulator of Ras emphasizing its role in fine-tuning signal cascades that ensure balanced cellular function.

Neurofibromin's dysregulation is most commonly associated with neurofibromatosis type 1 a genetic disorder characterized by the development of benign tumors in the nervous system. The loss of neurofibromin function leads to unregulated Ras activity resulting in tumorigenesis. Additionally neurofibromin is implicated in certain sporadic cancers due to its role in controlling cell proliferation. In neurofibromatosis type 1 interactions between neurofibromin and proteins such as p53 a known tumor suppressor highlight its significance in disease pathways and tumor suppression mechanisms.
