HTF-3583 Recombinant YFP-Human SPIN4 Protein $300

Recombinant YFP-Human SPIN4 Protein

Product Name: Recombinant YFP-Human SPIN4 Protein
Catalog #:  HTF-3583
Manufacture:  LD Biopharma, Inc.

All five members of SPIN family contain three Tudor methyl reader domains, and therefore SPIN4 (Spindlin-4) is thought to bind methylated histones. SPIN4 exhibits H3K4me3-binding activity. Recent data indicated that DCAF16 interacts with and ubiquitinates SPIN4. DCAF16 is a substrate recognition component of Cullin-RING E3 ubiquitin ligases that can be targeted by electrophilic PROTACs (PROteolysis Targeting Chimeras) to promote the nuclear-restricted degradation of proteins.

Full-length human SPIN4 cDNA (248aa) was constructed with codon optimization gene synthesis and expressed with YFP Protein as N-terminal (YFP; 256aa) fusion protein in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
