DOCK3 Antibody

DOCK3 was detected in immersion fixed paraffin-embedded sections of human Alzheimer's brain (cortex) using Sheep Anti-Human DOCK3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7134) at 3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hemotoxylin (blue). Specific staining was localized to neurofibrillary tangles. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background

DOCK3 (Dedicator of cytokinesis protein 3; also MOCA and PBP) is a 230-240 kDa member of the DOCK family, DOCK180 superfamily of proteins. DOCK3 expression appears to be restricted to neurons where it binds to Rac1 in conjunction with WAVE1, enhancing both Rac1 activity and that of downstream JNK. This results in cytoskeleton rearrangement and the promotion of axonal outgrowth. DOCK3 also binds to beta -catenin, thereby inhibiting Wnt signaling and promoting cell adhesion. Human DOCK3 is 2030 amino acids (aa) in length. It contains one protein-interaction SH3 domain (aa 7-650), a DHR-1 region that localizes DOCK3 to cell membranes (aa 418-654), a DHR-2 domain that likely binds to nucleotide-free GTPases and shows GEF activity (aa 1122-1630), and one SH3-binding motif (aa 1970‑1976). There is one phosphorylation site at Ser2013 and, unlike DOCK180, DOCK3 is known to form intracellular aggregates. There are three potential isoform variants. Two result from the use of alternative start sites at Met346 and Met388, while a third shows a deletion of aa 106‑123 coupled to a Gly substitution for aa 184‑2030. Over aa 418-656, human DOCK3 shares 99% aa identity with mouse DOCK3.
