Protein function: Guanine nucleotide exchange factor that specifically activates the small GTPase SAR1B. Mediates the recruitement of SAR1B and other COPII coat components to endoplasmic reticulum membranes and is therefore required for the formation of COPII transport vesicles from the ER.

Primers are provided as a 40 µl solution containing both primers at a final concentration of 50 µM in 10 mM Tris-HCl (pH 7.5), 0.1 mM EDTA. Dilute with water as needed prior to use. This amount is sufficient for 1000 x 20µl PCR reactions assuming a final primer concentration of 0.1 µM. Add cDNA template....
