Purity ~90% (SDS-PAGE). LBH belongs to the LBH family and is highly expressed in heart, and expressed at low levels in placenta, lung, skeletal muscle, kidney and liver. This protein is a transcriptional activator which may act in mitogen-activated protein kinase signaling pathway. Source: Recombinant protein corresponding to aa1-105 from human LBH, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~14.6kD (128aa), confirmed by MALDI-TOF Applications: Suitable for use in SDS-PAGE.
