Anti-SCAMP2 antibody produced in rabbit

SCAMP2 (secretory carrier membrane protein 2) belongs to the SCAMP family of highly conserved integral membrane proteins, which are involved in cell surface recycling pathways). SCAMP2 is one of the two isoforms of SCAMP, the other being SCAMP1, and has a molecular weight of 39kDa. It has a wide range of tissue expression. It is a transmembrane protein, which contains a cytoplasmic N-terminal, cytoplasmic C-terminal tail and four transmembrane regions. It contains NHE5 (Na⁺/H⁺ exchanger)-binding sites in both its N- and C-termini. It also contains the characteristic E-peptide of SCAMP proteins, within the second and third transmembrane helices. This protein resides in endosomes, other recycling organelles, as well as plasma membrane.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

SCAMP2 (secretory carrier membrane protein 2) is involved in Ca²⁺-dependent granule exocytosis, and is a part of the later stages of membrane fusion. It controls the formation of membrane fusion pores, by sequestering phosphatidylinositol 4,5-bisphosphate (PIP2) within membranes. It interacts with PIP2 via a hydrophobic sequence CWYRPIYKAFR, present in its structure. It interacts with serotonin and dopamine transporters, and controls their subcellular distribution and their surface expression. It interacts with NHE5, which is a Na⁺/H⁺ exchanger highly expressed in brain, through its cytoplasmic N- and C-termini. This way, it regulates the movement of NHE5 through recycling endosomes, and its cell surface targeting, in the presence of Arf6 (ADP-ribosylation factor 6). The E-peptide of SCAMP2 protein is a potent inhibitor of exocytosis during the later stages.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
