Purity ~85% (SDS-PAGE). Probably plays a role in facilitating the assbly of multimeric protein complexes inside the endoplasmic reticulum. Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10, probably to facilitate the release of DNAJC10 from its substrate. Source: Recombinant protein corresponding to aa25-293 from human HSPA5, fused to His-Tag at N-terminal, expressed in E. coli. Molecular Weight: ~33.7kD AA
