The T-cell receptor (TCR) genes (alpha, beta, delta, and gamma) are comprised of numerous, discontinuous coding segments that somatically rearrange to produce heterodimeric cell surface T-cell receptors, either alpha/beta (90%-95% of T cells) or gamma/delta (5%-10% of T cells).
Alternative splicing is known to be involved in the regulation of normal physiological functions as well as pathologies. For example, a number of alternatively spliced genes in immunity are known. Studies indicate that alternative splicing of CD44, a protein involved in T cell homing with 10 variable cassette exons and six distinct protein isoforms, is crucial for T cell function.
