SSR1 (signal sequence receptor, a) 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 a (TRAPA) and is one of the four subunits making the TRAP complex.
Synonyms: Anti-SSR-alpha; Anti-Signal sequence receptor subunit alpha; Anti-TRAP-alpha; Anti-Translocon-associated protein subunit alpha precursor
Storage: -20C
Application: Anti-SSR1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). 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, a) 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.
