While this phenomenon is known to increase complexity at the transcriptome level, the effect
of alternative splicing on the complexity at the proteomic level remains controversial.

alternative splicing of more than 100 genes reacts extremely sensitively to changes in temperature, so that different proteins are produced depending
on the time
of day and body temperature,» said Prof. Dr. Florian Heyd.
