General description
SSR1 (signal sequence receptor, α) is an endoplasmic reticulum (ER) membrane protein, which is predominantly localized to rough ER. Its molecular weight is 34kDa. It is a type I membrane protein and is also found in the nuclear envelope. This gene is localized to human chromosome 6. It is also known as translocon-associated protein α (TRAPA) and is one of the four subunits making the TRAP complex.
Immunogen
Translocon-associated protein subunit alpha precursor recombinant protein epitope signature tag (PrEST)
Application
Anti-SSR1 antibody produced in rabbit has been used in selective permeabilization immunofluorescence (2μg/ml).
Anti-SSR1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem/physiol Actions
The function of SSR1 (signal sequence receptor, α) is not yet fully characterized. It is a calcium binding protein. It forms part of the translocon-associated protein (TRAP) complex, which is involved in the endoplasmic reticulum-associated degradation (ERAD) pathway. This protein is induced by granulocyte-macrophage colony-stimulating factor (GM-CSF), which might be an outcome of unfolded protein response due to the accumulation of improperly folded proteins. Also this gene is located in the schizophrenia susceptibility locus.
Features and Benefits
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:
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.
