Abstract

Sterile alpha motif (SAM) domains are known to exhibit diverse protein-protein interaction modes. They can form multiple self-association architectures and also bind to various non-SAM domain-containing proteins. Surprising new work adds a completely unanticipated function for some SAM domains - the ability to bind RNA. Such functional diversity within a homologous protein family presents a significant challenge for bioinformatic function assignment.
