A cDNA clone (rpS13) encoding the S13 ribosomal protein (rpS13) has be
en isolated from the catfish Ictalurus punctatus, and is the first exa
mple of an rpS13 isolated from a teleost species. The deduced 151-amin
o-acid (aa) sequence is 96% identical to the rat and human rpS13, exte
nding the evolutionary conservation of this protein.
