Purity ~85% (SDS-PAGE). HSF2 binding protein (HSF2BP) associates with HSF2. The interaction occurs between the trimerization domain of HSF2 and the amino terminal hydrophilic region of HSF2BP that comprises two leucine zipper motifs. HSF2BP may therefore be involved in modulating HSF2 activation. Source: Recombinant protein corresponding to aa1-334 from human HSF2BP, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~40kD (357aa), confirmed by MALDI-TOF Applications: Suitable for use in SDS-PAGE.
