title: Specificity in signaling pathways: assembly into multimolecular signaling complexes.
abstract: A critical issue in the field of signal transduction is how signaling molecules are organized into different pathways within the same cell. The importance of assembling signaling molecules into architecturally defined complexes is emerging as an essential cellular strategy to ensure specificity and selectivity of signaling. Scaffold proteins function as the pillars of these transduction complexes, bringing together a diversity of signaling components into defined ultramicrodomains of signaling.
