SEC13 belongs to the SEC13 family of WD-repeat proteins. It is a constituent of the endoplasmic reticulum and the nuclear pore complex. It has similarity to the yeast SEC13 protein, which is required for vesicle biogenesis from endoplasmic reticulum during the transport of proteins. This protein is Interacts with SEC31A and SEC31B. SEC31A was found to colocalize with SEC13, one of the other components of COPII, in the subcellular structures corresponding to the vesicle transport function. Source: Recombinant corresponding to aa1-322 from human SEC13, fused to His-tag at N-terminus expressed in E.coli.
