Alternative pre-mRNA processing regulates cell-type specific expression of the <Emphasis Type="Italic">IL4l1</Emphasis> and <Emphasis Type="Italic">NUP62</Emphasis> genes

Background  

Given the complexity of higher organisms, the number of genes encoded by their genomes is surprisingly small. Tissue specific regulation of expression and splicing are major factors enhancing the number of the encoded products. Commonly these mechanisms are intragenic and affect only one gene.
