Purity: > 90% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH8.0) containing 50% glycerol, 0.2M NaCl, 5mM DTT, 2mM EDTA. SYF2, also known as pre-mRNA-splicing factor SYF2, may be involved in pre-mRNA splicing. This protein interacts with cyclin D-type binding-protein 1, which is thought to be a cell cycle regulator at the G1/S transition. It is abundantly expressed in the heart, skeletal muscle and kidney and is expressed at lower levels in other tissues. Recombinant human SYF2 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer.
