Abstract
The immunoglobulin gene which encodes both membrane-associated and secreted proteins through alternative RNA processing reactions has been a model system used for over 25 yr to better understand the regulatory mechanisms governing alternative RNA processing. This gene contains competing cleavage- polyadenylation and RNA splicing reactions and the relative use of the two pathways is differentially regulated between B cells and plasma cells. General cleavage-polyadenylation and RNA splicing reactions are both altered during B cell maturation to affect immunoglobulin expression. However, the specific factors involved in this regulation have yet to be identified clearly. As transcriptional regulators stimulate the developmental RNA processing switch, microarray analysis is a promising approach to identify candidate regulators of this complex RNA processing mechanism.
