General description
Wiskostatin is a dibrominated carbazole. The N-alkylated side chain has a chiral hydroxyl group and a terminal tertiary amine.
Application
Wiskostatin has been used:
- as a small-molecule inhibitor of Wiskott-Aldrich syndrome protein (WASP) in human osteosarcoma U2OS cells and mouse-tail fibroblast cell lines
- as a neural (N)-WASP inhibitor in cultured neurons and in the human embryonic kidney (HEK293) cells expressing HA-Parkin
- as a neural (N)-WASP inhibitor in dorsal root ganglion (DRG) cells to investigate vascular endothelial growth factor (VEGF) effect on the actin related protein 2/3 complex (Arp 2/3)
Biochem/physiol Actions
Wiskostatin is a selective inhibitor of N-WASP, a ubiquitously expressed member of the Wiskott-Aldrich Syndrome protein (WASp) family that regulates actin polymerization.
Wiskostatin is a selective inhibitor of N-WASP, a ubiquitously expressed member of the Wiskott-Aldrich Syndrome protein (WASp) family that regulates actin polymerization. Wiskostatin inhibits actin-dependent cellular functions, including migration, transmembrane transport and phagocytosis.
Wiskostatin mediates the inhibition of cytokinesis. It interacts with WASP especially at the regulatory guanosine-5′-triphosphate (GTP)ase-binding domain (GBD).

Negative regulation of receptor signaling is essential for controlling cell activation and differentiation. In B-lymphocytes, the down-regulation of B-cell antigen receptor (BCR) signaling is critical for suppressing the activation of self-reactive B cells; however, the mechanism underlying the negative regulation

Nuclear actin-based movements have been shown to orchestrate clustering of DNA double-strand breaks (DSBs) into homology-directed repair domains. Here we describe multiscale three-dimensional genome reorganization following DNA damage and analyze the contribution of the nuclear WASP-ARP2/3-actin pathway toward chromatin topology
