Association of Ras protein with the inner surface of the plasma membrane is required for Ras signaling activity. Farnesyl thiosalicylic acid (FTS) is an inhibitor of Ras-mediated signaling that functions by dislodging Ras from the cell membrane thereby rendering it susceptible to proteolytic degradation. FTS...

Risperidone-d5 is intended for use as an internal standard for the quantification of risperidone (Cay-13629) by GC- or LC-MS. Risperidone is an atypical antipsychotic that binds to dopamine D2 receptors (Ki = 3 nM) and the serotonin (5-HT) receptor subtype 5-HT2A (Ki = 0.12 nM). It also binds to dopamine D4, alpha1-...

Retinol is an essential micronutrient that plays a critical role in various physiological functions including cell growth and differentiation. Due to the instability and low solubility of retinol in the aqueous medium, it requires specific binding proteins in body fluids and within the cell for transport....

CD4 is a type I transmembrane glycoprotein that functions as a T cell receptor (TCR) co-receptor. It exists as a single polypeptide chain composed of four extracellular immunoglobulin-like (Ig-like) domains that interact with MHC class II molecules, a transmembrane domain, and a cytoplasmic tail that associates with...
