ECM BIOSCIENCES/Abp1 (C-terminal region) Antibody/100 μl/AM3341

Cellular morphology, adhesion, and motility occur through dynamic reorganization of actin-based superstructures. Actin-binding proteins are critical for regulating actin polymerization and superstructure formation. The Arp2/3 complex is an actin polymerization-inducing complex that includes Arp2, Arp3, p41-Arc, p34-Arc, p21-Arc, p20 Arc, and p16-Arc. Several actin binding proteins, WASP, cortactin, and Abp1, regulate the activity of the Arp2/3 complex. Abp1 (SH3P7, HIP-55) is the mammalian homologue of the yeast Abp1p, which has been shown to bind actin and to have roles in endocytosis. Abp1 contains a C-terminal Src homology 3 domain and an N-terminal actin depolymerization factor (ADF-H/C) domain that is homologous to a similar domain found in the actin severing protein, cofilin. Abp1 can bind Src kinases, hematopoietic progenitor kinase 1 (HPK-1), myosin I heavy chain kinase, and dynamin. Thus, Abp1 may be important for regulation of the actin cytoskeleton through its ability to interact with F-actin and various other cytoskeletal and cell signaling proteins.

Western blot of Jurkat (lane 1), HeLa (lane 2), mouse brain (lane 3), and A431 (lane 4). The blot was probed with mouse monoclonal anti-Abp1 (C-terminal region) antibody at 1:500.

Immunocytochemical labeling of Abp1 in aldehyde-fixed and NP-40-permeabilized differentiated A431 cells. The cells were labeled with mouse monoclonal anti-Abp1 (AM3341) antibody, then the antibody was detected using appropriate secondary antibody conjugated to DyLight® 594. The cells were counterstained with Sytox green to label nuclei.

Clone (M334) was generated from a recombinant sequence that included amino acids in the C-terminal region of human Abp1.
