COP9 signalosome component CSN-5 stabilizes PUF proteins FBF-1 and FBF-2 in Caenorhabditis elegans germline stem and progenitor cells.

Antagonistic control of Caenorhabditis elegans germline stem cell proliferation and differentiation by PUF proteins FBF-1 and FBF-2.

LST-1 weakens FBF-2 binding affinity for short and long motifs, which may increase target selectivity.
Title: A crystal structure of a collaborative RNA regulatory complex reveals mechanisms to refine target specificity.
Data indicate that a 10-amino-acid region in germline development defective-3 (GLD-3) is required for fem-3 binding factor (FBF) binding, while a 7-amino-acid loop in FBF between PUF repeats 7 and 8 is necessary for GLD-3 binding.
Title: A protein.protein interaction platform involved in recruitment of GLD-3 to the FBF.fem-3 mRNA complex.
Data show that CPB-1 (cytoplasmic polyadenylation element binding protein homolog-1) alters the affinity of FBF (fem-3 mRNA binding factor) for specific RNA sequences.
Title: Biochemical characterization of the Caenorhabditis elegans FBF.CPB-1 translational regulation complex identifies conserved protein interaction hotspots.
findings show FBF-1 and FBF-2 have different effects on target mRNAs; FBF-2 prevents translation; FBF-2 activity depends on PGL-1; PGL-1 is required to localize FBF-2 to perinuclear P granules and for efficient binding of FBF-2 to its mRNA targets
Title: The P granule component PGL-1 promotes the localization and silencing activity of the PUF protein FBF-2 in germline stem cells.
Data suggest that the FBF-2/GLD-2 protein directed polyadenylation of the endogenous mRNA, compensating for that mRNA's natural deadenylation.
Title: Targeted translational regulation using the PUF protein family scaffold.
The Puf RNA-binding proteins FBF-1 and FBF-2 inhibit the expression of synaptonemal complex proteins in germline stem cells.

fbf-2 regulates the size of the mitotic region in helminth germ cells.
Title: FBF-1 and FBF-2 regulate the size of the mitotic region in the C. elegans germline.
FBF may coordinately repress sperm-specifying mRNAs to direct oogenesis and it represses the fog-1 mRNA to maintain FOG-1 at a low level appropriate for proliferation
