Classical PUF proteins bind to single-stranded RNA with sequence specificity that can be engineered by site-directed mutagenesis according to a simple RNA-recognition code. Now in-depth probing of the PUF RNA-recognition code enhances future design of PUF proteins and exposes hidden complexity in generating specificity.
