Descrizione

Descrizione generale

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.

Specificità

Ser2152 of human and murine Filamin-A isoform 1 (P21333-1 & Q8BTM8-1) corresponds to Ser2144 of human Filamin-A isoform 2 (P21333-2). Equivalent site is not present in murine spliced isoform 2.

Immunogeno

Epitope: Filamin repeat 20

KLH-conjugated linear peptide corresponding to the Filamin repeat 20 of human phospho-Filamin-A (Ser2152).

This Anti-phospho-Filamin-A (Ser2152) Antibody, clone PS2 is validated for use in Western Blotting, Immunocytochemistry and Immunofluorescence for the detection of phospho-Filamin-A (Ser2152).

Western Blotting Analysis: A representative lot detected enhanced FLN-A Ser2152 phosphorylation in multiple tissue extracts (liver, heart, brain, and skin) from new born (P0) and E16.5 embryos of Arfgef2/Big2 knockout mice when compared with stage-matched tissue samples from wild-type mice (Zhang, J., et al. (2012). J. Neurosci. 32(36):12619-12629).
Western Blotting Analysis: A representative lot detected cellular FLN-A pSer2152 phosphorylation induction upon serum, forskolin, or EphB2-Fc addition to serum-starved CHP100 human neuroblastoma cells (Zhang, J. et al. (2013). J. Neurosci. 33(40):15735-15746).
Immunocytochemistry Analysis: A representative lot detected cellular FLN-A pSer2152 phosphorylation induction in neuronal progenitors from frontal cortex of E13.5–E14.5 mouse embryos, CHP100 human neuroblastoma cells, and A7, but not FLN-A-deficient M2, human melanoma cells upon forskolin addition (Zhang, J. et al. (2013). J. Neurosci. 33(40):15735-15746).
Immunofluorescence Analysis: A representative lot detected FLN-A pSer2152 immunoreactivity extended to the proliferative zone (PZ) surface at the periventricular heterotopia (PVH) congenital malformation site in the forebrain (FB) of E17.5 MEKK-/- mouse embryos in addition to the FLN-A pSer2152 immunoreactivity in the intermediate zone (IZ) and cortical plate (CP) seen in both wild-type and MEKK-knockout embryos by fluorescent immunohistochemistry (Sarkisian, M.R., et al. (2006). Neuron. 52(5):789-801).
