- Extra Details:
- Regulator of G-protein signaling (RGS) proteins contain an 120aa conserved domain, termed the RGS domain, that acts as a GTPase-activating protein that acts to reduce the signal transmitted by the receptor-activated G-alpha subunit. RGS21 is a recently identified member of this family that has been reported to be selectively expressed in subpopulations of taste bud cells and co-expressed with bitter and sweet transduction components such as alpha-gusticin, phospholipase Cbeta2, T1R2/T1R3 sweet taste receptors and T2R bitter taste receptors. Other reports indicate that RGS21 is more widely expressed. Binding assays demonstrate that RGS21 binds alpha-gusticin in a conformation-dependent manner and may do the same with T1R receptors, suggesting that RGS21 may play a role in sweet and bitter taste transduction processes. Applications: Suitable for use in ELISA, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5ug/ml Immunofluorescence: 20ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Human spleen Cell Lysate Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
