Abstract

A great many transcription factors, cytokines, and cytokine receptors have been identified as indispensable elements in lymphocyte differentiation, but the molecular mechanism that orchestrates the expression and function of these molecular factors is unknown. The process of lymphocyte differentiation involves both the simultaneous activation of lymphoid-related genes and the inactivation of non-lymphoid lineage-related genes, suggesting that there should be critical molecules that regulate such gene expression in both temporal and spatial dimensions. Recent studies of chromatin-remodeling proteins shed light on this complex process. In particular, special AT-rich sequence-binding protein 1 has been studied extensively. In this article, we review the wealth of information characterizing this protein.
