Anti-phospho-Filamin-A (Ser2152) Antibody, clone PS2 clone PS2, from mouse

Filamin-A (UniProt P21333; also known as ABP-280, Actin binding protein 280, Alpha-filamin, Endothelial actin-binding protein, Filamin-1, FLN-A, Non-muscle filamin) is encoded by the FLNA (also known as ABP, CSBS, CVD1, FLN, FLN1, FMD, MNS, NHBP, OPD, OPD1, OPD2, XLVD, XMVD) gene (Gene ID 2316) in human. Filamin-A (FLN-A) is an actin-binding protein essential for cytoskeletal rearrangement and cell locomotion. Serine 2152 of FLN-A is a PKA phosphorylation target. FLN-A S2152 phosphorylation is essential for FLN-A-mediated recruitment of signaling proteins, adhesion molecules, and the vesicle-trafficking complex to the peripheral actin rim, so as to stabilize the cortical structure and epithelial membrane. Mutations in FLNA and ARFGEF2 genes cause periventricular heterotopia (PVH or PH), a congenital malformation of cortical development characterized by a reduced brain size and ectopic neuronal nodules along the ventricular neuroepithelium as a result of impaired initiation of neuronal migration. Suppression of either Arfgef2 or Mekk4 results in increased cellular FLN-A level and Ser2152 phosphorylation. In addition, Arfgef2 or Mekk4 deletion causes PVH in knockout mice.
