Abstract
Filamin plays an important role in actin cytoskeleton organization, membrane stabilization, and anchoring of transmembrane proteins. Using short interfering RNA (siRNA) to selectively target the filamin A gene and silence its expression, we studied the role of filamin A in G protein coupled receptor (GPCR) signaling. Silencing of filamin A protein expression was determined by immunoblotting and immunofluorescence. Functional consequences of filamin A gene silencing were measured by studying its role in MAPK signaling pathways activated by the Ca2+-sensing receptor. This work defines filamin A involvement in GPCR signaling pathways and describes an additional method for studying its function.
