Protein modeling studies reveal that the RG-rich region is part of a three to four strand antiparallel beta-sheet, which in other RNA binding protein functions as a platform for nucleic acid interactions.

Heterogeneous nuclear ribonucleoparticle (hnRNP) proteins form a family of RNA binding proteins (RBPs) that coat nascent pre-mRNAs.

Finally, we have found that Pumilio2, a member of the PUF family of RNA-binding proteins, is highly concentrated at the vertebrate neuromuscular junction.

PUF proteins comprise a highly conserved family of sequence-specific RNA-binding protein that regulate target mRNAs.
