Purity ~90% (SDS-PAGE). Heat shock factor binding protein 1-like, also known as HSBP1L1, belongs to a family of eukaryotic proteins identified as nucleotide exchange factors for HSP 70, which exhibit varying degrees of compartment and species specificity. This gene expression is regulated primarily at the transcription level. Source: Recombinant protein corresponding to aa1-74 from human HSBP1L1, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~10.8kD (97aa) Applications: Suitable for use in SDS-PAGE.
