ABSTRACT The structure of the recombinant Escherichia coli protein YbcJ, a representative of a conserved family of bacterial proteins (COG2501), was determined by nuclear magnetic resonance. The fold of YbcJ identified it as a member of the larger family of S4-like RNA binding domains. These domains bind to structured RNA, such as that found in tRNA, rRNA, and a pseudoknot of mRNA. The structure of YbcJ revealed a highly conserved patch of basic residues, comprising amino acids K26, K38, R55, K56, and K59, which likely participate in RNA binding.

Abstract FOG-1 controls germ cell fates in the nematode Caenorhabditis elegans. Sequence analyses revealed that FOG-1 is a cytoplasmic polyadenylation element binding (CPEB) protein; similar proteins from other species have been shown to bind messenger RNAs and regulate their translation. Our analyses of fog-1 mutations indicate that each of the three RNA-binding domains of FOG-1 is essential for activity. In addition, biochemical tests show that FOG-1 is capable of binding RNA sequences in the 3′-untranslated region of its own message. Finally, genetic assays reveal that fog-1 functions zygotically, that the small fog-1 transcript has no detectable function, and that missense mutations in fog-1 cause a dominant negative phenotype. This last observation suggests that FOG-1 acts in a complex, or as a multimer, to regulate translation. On the basis of these data, we propose that FOG-1 binds RNA to regulate germ cell fates and that it does so by controlling the translation of its targets. One of these targets might be the fog-1 transcript itself.

The poly(A)-binding protein (PABP) is the major mRNA-binding protein in eukaryotes, and it is essential for viability of the yeast Saccharomyces cerevisiae. The amino acid sequence of the protein indicates that it consists of four ribonucleoprotein consensus sequence-containing RNA-binding domains (RBDs I, II, III, and IV) and a proline-rich auxiliary domain at the carboxyl terminus. We produced different parts of the S. cerevisiae PABP and studied their binding to poly(A) and other ribohomopolymers in vitro. We found that none of the individual RBDs of the protein bind poly(A) specifically or efficiently. Contiguous two-domain combinations were required for efficient RNA binding, and each pairwise combination (I/II, II/III, and III/IV) had a distinct RNA-binding activity. Specific poly(A)-binding activity was found only in the two amino-terminal RBDs (I/II) which, interestingly, are dispensable for viability of yeast cells, whereas the activity that is sufficient to rescue lethality of a PABP-deleted strain is in the carboxyl-terminal RBDs (III/IV). We conclude that the PABP is a multifunctional RNA-binding protein that has at least two distinct and separable activities: RBDs I/II, which most likely function in binding the PABP to mRNA through the poly(A) tail, and RBDs III/IV, which may function through binding either to a different part of the same mRNA molecule or to other RNA(s).
