Scientific Data Images for Human Doc2 alpha Antibody

Doc2a antibody in Human Brain by Immunohistochemistry (IHC-P).

Doc2 alpha in Human Brain.

Doc2a was detected in immersion fixed paraffin-embedded sections of human brain (hippocampus) using Mouse Anti-Human Doc2a Monoclonal Antibody (Catalog # MAB7904) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Doc2 alpha

DOC2A/Doc2 alpha (Double C2-like domain containing protein alpha) is a 44 kDa (predicted) monomeric member of the C2 domain-containing protein family of molecules. It is expressed in both neurons and mast cells and appears to serve as an intracellular Ca++ sensor protein that regulates secretory vesicle release. In neurons, Doc2 alpha is normally bound to synaptic vesicles and interacts with Munc13-1 to promote secretory vesicle exocytosis through the cell membrane. In mast cells, a similar process occurs that involves Munc13-4 instead of Munc13-1. Human Doc2 alpha is 400 amino acids (aa) in length. It contains a Mid domain (aa 13-37) that binds Munc13‑1, followed by one C2 domain that binds Ca++ and lipid (aa 91-195) and a second C2 domain that binds SNAP25 (253-356). There is one potential alternative start site 16 aa upstream of the standard site. Over aa 1-114, human Doc2 alpha shares 90% aa sequence identity with mouse Doc2 alpha. Human DOC2B is the product of a separate gene and shares no meaningful aa sequence identity (<30%) with human Doc2 alpha.
