[https://www.uniprot.org/uniprot/PGL1_CAERE PGL1_CAERE] Guanyl-specific endoribonuclease which cleaves the phosphodiester bond in single-stranded RNA between the 3'-guanylic residue and the 5'-OH residue of adjacent nucleotide, resulting in the formation of a corresponding 2',3'-cyclic phosphate intermediate (PubMed:26787882). Essential role in male and female postembryonic germline development; maternally provided protein maintains a population of proliferating germ cells and zygotic expression is required for correct oogenesis (By similarity). Together with the P-granule component pgl-3, is involved in the formation of P-granules (By similarity). Together with pgl-3, probably recruits other granule components such as pos-1, mex-3 and glh-1 to P-granules (By similarity). In addition, may act redundantly with pgl-3 to protect germ cells from excessive germline apoptosis during normal oogenesis and development of the two gonadal arms (By similarity). This may in part be through regulating the localization of sir-2.1 which is involved in germ cell apoptosis (By similarity). May protect somatic cells from excessive apoptosis during normal development (By similarity).[UniProtKB:Q9TZQ3]<ref>PMID:26787882</ref>

Cellular RNA-protein (RNP) granules are ubiquitous and have fundamental roles in biology and RNA metabolism, but the molecular basis of their structure, assembly, and function is poorly understood. Using nematode "P-granules" as a paradigm, we focus on the PGL granule scaffold protein to gain molecular insights into RNP granule structure and assembly. We first identify a PGL dimerization domain (DD) and determine its crystal structure. PGL-1 DD has a novel 13 alpha-helix fold that creates a positively charged channel as a homodimer. We investigate its capacity to bind RNA and discover unexpectedly that PGL-1 DD is a guanosine-specific, single-stranded endonuclease. Discovery of the PGL homodimer, together with previous results, suggests a model in which the PGL DD dimer forms a fundamental building block for P-granule assembly. Discovery of the PGL RNase activity expands the role of RNP granule assembly proteins to include enzymatic activity in addition to their job as structural scaffolds.
