Application

When exposed to cells or tissue lysates, biotinylated isoxazole (b-isox) was shown to precipitate RNA-binding proteins with significant overlap to the components of RNA granules. By reversibly aggregating and disaggregating structures similar to RNA granules, b-isox has lent insight to polypeptides necessary for the reversible aggregation of RNA-binding proteins.

This product was previously listed as T511617.

Many RNA regulatory proteins controlling pre-messenger RNA splicing contain serine:arginine (SR) repeats. Here, we found that these SR domains bound hydrogel droplets composed of fibrous polymers of the low-complexity domain of heterogeneous ribonucleoprotein A2 (hnRNPA2). Hydrogel binding was reversed upon
