Introduction
PAIP2 acts as a repressor in the initiation of translation for poly(A)-containing mRNAs. It inhibits translation by acting on PABPC1, disrupting its interaction with poly(A) RNA. PAIP2 competes with PAIP1 to bind with PABPC1. When PAIP2 binds to PABPC1, it disrupts the cytoplasmic poly(A) RNP structure organization.
Description
Recombinant Human PAIP2, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 147 amino acids (amino acids 1-127). It has a molecular mass of 17.1 kDa. This recombinant PAIP2 is fused to a 20 amino acid His Tag at the N-terminus and is purified using standard chromatographic techniques.
Physical Appearance
Sterile, colorless solution free of particles.
Formulation
The PAIP2 protein solution is formulated in 20mM Tris-HCl buffer with a pH of 8, 1mM DTT, and 10% Glycerol.
Stability
For short-term storage (2-4 weeks), keep at 4°C. For longer storage, freeze at -20°C. Adding a carrier protein like 0.1% HSA or BSA is recommended for long-term storage. Avoid repeatedly freezing and thawing.
Purity
Purity is greater than 90% as determined by SDS-PAGE analysis.
