Introduction
GIPC1, a PDZ domain-containing protein, interacts with RGS-GAIP and the viral oncoprotein TAX. TAX activates viral and cellular promoters through interactions with various transcription factors. GIPC1 is primarily located in vesicle clusters near the plasma membrane and plays a role in G protein-coupled signaling pathways. It participates in regulating clathrin-coated vesicular trafficking. Additionally, GIPC1 interacts with membrane-bound Semaphorin F, involved in neuronal axon growth, and regulates the subcellular distribution of M-SemF in the brain.
Description
Recombinant Human GIPC1, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 353 amino acids (1-333 a.a). It has a molecular weight of 38.2 kDa. The GIPC1 protein is fused to a 20 amino acid His-Tag at the N-terminus and purified using proprietary chromatographic techniques.
Physical Appearance
A sterile, colorless solution that has been filtered.
Formulation
Human GIPC1 solution (0.5 mg/ml) in a buffer containing 20 mM Tris-HCl (pH 8), 1 mM DTT, 0.1 M NaCl, 1 mM EDTA, and 20% glycerol.
Stability
For short-term storage (2-4 weeks), keep at 4°C. For extended storage, freeze 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 95.0% as assessed by SDS-PAGE.
