背景信息

The FKHRL1 (Phospho-Ser321) antibody is designed to detect Forkhead Box O3 (FOXO3a), a transcription factor involved in regulating apoptosis, cell cycle arrest, and oxidative stress resistance. FKHRL1. also known as FOXO3a, becomes functionally regulated through phosphorylation at specific residues, including Serine 321. Phosphorylation at Ser-321. mediated by kinases such as Akt (Protein Kinase B) or SGK (Serum/Glucocorticoid-Regulated Kinase), promotes the nuclear exclusion of FOXO3a by facilitating its binding to 14-3-3 proteins. This sequesters FOXO3a in the cytoplasm, inhibiting its transcriptional activity and suppressing pro-apoptotic or cell cycle-regulating target genes. The Phospho-Ser321 antibody specifically recognizes this post-translational modification, enabling researchers to study FOXO3a activation status in cellular signaling pathways, particularly the PI3K/Akt pathway. It is widely used in applications like Western blotting, immunofluorescence, and immunohistochemistry to investigate conditions such as cancer, aging, and metabolic disorders, where dysregulation of FOXO3a phosphorylation is often implicated. This antibody helps elucidate mechanisms linking growth factor signaling, stress responses, and cellular survival.
