A schematic diagram of alternative transcription start sites (TSSs) and the classes of TSS switching. a Alternative TSSs can generate different splicing variants that can be translated into different protein isoforms. *the functional domains may be affected by alternative TSSs which results in functional diversity. b Different outcomes comparing alternative TSS usage at two time points – no TSS switching, non-crossover TSS switching or crossover TSS switching. Y-axis represents the quantitative measure of TSS usage measured by the expression level of its mRNA transcript. X-axis represents the two developmental time points used in the comparison (t1 vs. t2)
