Introduction
WIBG, a cooperating partner of Mago-Y14, forms the Mago-Y14 heterodimer, a crucial protein in the exon junction complex (EJC). Deposited on mRNAs during splicing, the EJC influences post-splicing mRNA metabolism. WIBG, a cytoplasmic RNA-binding protein, is excluded from the nucleus by Crm1 and interacts directly with Mago-Y14 through its N-terminal domain.
Description
Recombinant Human WIBG, produced in E. coli, is a single, non-glycosylated polypeptide chain of 212 amino acids (1-204 a.a.) with a molecular weight of 23.7 kDa. An 8 amino acid His-Tag is fused to the C-terminus. Purification is achieved using proprietary chromatographic techniques.
Physical Appearance
A clear, colorless solution, sterile-filtered.
Formulation
WIBG Human solution in 20mM Tris buffer (pH 8.0), containing 0.1M NaCl and 10% glycerol.
Stability
For short-term storage (2-4 weeks), store at 4°C. For longer periods, store frozen at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
Purity exceeds 85.0% as determined by SDS-PAGE analysis.
Synonyms
PYM, Partner of Y14 and mago, MGC13064, WIBG, BCGN Homolog, Protein wibg homolog.
