Application Dilution Species-Reactivity Sensitivity MW (kDa) Isotype
W Human Endogenous 110 Rabbit IgG
IF-IC

Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IF-IC=Immunofluorescence (Immunocytochemistry)

Specificity / Sensitivity

FoxM1 (D12D5) XP® Rabbit mAb detects endogenous levels of total FoxM1 protein. This antibody is predicted to recognize all three isoforms (FoxM1a, FoxM1b and FoxM1c).

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein to human FoxM1b.

Western Blotting

Western Blotting

Western blot analysis of extracts of HeLa cells, synchronized at the G1/S border by aphidicolin treatment (2 μM, 24 hours), using FoxM1 (D12D5) XP® Rabbit mAb.

IF-IC

IF-IC

Confocal immunofluorescent analysis of HeLa cells, untreated (left) or synchronized at the G1/S border by aphidicolin treatment (right), using FoxM1 (D12D5) XP® Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red).

Background

Forkhead box M1 (FoxM1) is a forkhead box family transcription factor that regulates a number of genes throughout the cell cycle to help control DNA replication, mitosis, and cell proliferation. FoxM1 expression increases during G1 and S and reaches maximum levels in G2/M (1-3). Nuclear translocation occurs just before entry into G2/M and is associated with FoxM1 phosphorylation (4). Phosphorylation of FoxM1 by MAPK (Ser331, Ser704), Cyclin/Cdk (Ser4, Ser35, Thr600, Thr611, Thr620, Thr627, Ser638), Plk1 (Ser715, Ser724), and Chk2 (Ser376) stabilizes and activates FoxM1 (4-8). Forkhead box M1 is expressed in all embryonic tissues but is restricted to proliferating tissues in adults (9). Research studies show that FoxM1 expression is negatively regulated by p53 (10,11). Upregulation of FoxM1 is associated with many human cancers, including prostate, breast, lung, ovary, colon, pancreas, stomach, bladder, liver, and kidney, and may be associated with p53 mutations in some tumors (11,12). As a result, FoxM1 inhibitors have become a topic of interest for potential cancer therapy (13).
