Summary: Enables mRNA 3'-UTR binding activity; mRNA 5'-UTR binding activity; and single-stranded RNA binding activity. Involved in several processes, including negative regulation of macromolecule metabolic process; positive regulation of female gonad development; and positive regulation of oocyte development. Located in P granule and cytosol. Is expressed in several structures, including AB; C; germ line; oocyte; and ventral nerve cord. Orthologous to human QKI (QKI, KH domain containing RNA binding).

Gld-1; puf-8 double-mutant germ cells begin to express the meiotic marker HIM-3, lose P granules, and form the sperm-specific membranous organelle, which are characteristics of developing spermatocytes.
Title: PUF-8 Functions Redundantly with GLD-1 to Promote the Meiotic Progression of Spermatocytes in Caenorhabditis elegans.
We examine GLD-1-binding motifs among targets conserved in C. elegans and C. briggsae and find that most, but not all, display evidence of shared ancestral binding sites.
Title: Evolutionary Dynamics of GLD-1-mRNA complexes in Caenorhabditis nematodes.
The study demonstrates that the QUA2 domain distinguishes GLD-1 from other members of the STAR family and contributes more generally to the modulation of RNA-binding affinity and specificity of KH domain containing proteins.
Title: Structural and functional implications of the QUA2 domain on RNA recognition by GLD-1.
Results show the RNA-binding protein GLD-1 in C. elegans affects multiple microRNA pathways and interacts with proteins required for microRNA function.
Title: RNA-binding protein GLD-1/quaking genetically interacts with the mir-35 and the let-7 miRNA pathways in Caenorhabditis elegans.
Our results demonstrate that both proteins recognize the glp-1 3' untranslated region (UTR) through adjacent, overlapping binding sites and that POS-1 binding excludes GLD-1 binding
