Characterization of the interaction between neuronal RNA-binding protein HuD and AU-rich RNA.
Hu proteins have been shown to bind to AU-rich elements (AREs) in the 3'-untranslated region of unstable mRNAs. They can thereby inhibit the decay of labile transcripts by antagonizing destabilizing proteins that target these AU-rich sequences. Here we examine the sequence preferences of HuD to elucidate its possible role in counteracting mRNA decay. Using repeats of the prototype destabilizing...
متن کاملThe RNA-binding protein HuD: a regulator of neuronal differentiation, maintenance and plasticity.
mRNA stability is increasingly recognized as being essential for controlling the expression of a wide variety of transcripts during neuronal development and synaptic plasticity. In this context, the role of AU-rich elements (ARE) contained within the 3' untranslated region (UTR) of transcripts has now emerged as key because of their high incidence in a large number of cellular mRNAs. This impor...
متن کاملThe RNA-binding protein HuD regulates neuronal cell identity and maturation.
Neural Hu proteins (HuB/C/D) are RNA-binding proteins that have been shown to induce neuronal differentiation activity when overexpressed in immature neural progenitor cells or undifferentiated neuronal tumors. Newly generated HuD-deficient mice exhibited a transient impaired-cranial-nerve-development phenotype at an early embryonic stage. Adult HuD-deficient mice exhibited an abnormal hind-lim...
متن کاملPoly(A) tail length-dependent stabilization of GAP-43 mRNA by the RNA-binding protein HuD.
The neuronal ELAV-like RNA-binding protein HuD binds to a regulatory element in the 3'-untranslated region of the growth-associated protein-43 (GAP-43) mRNA. Here we report that overexpression of HuD protein in PC12 cells stabilizes the GAP-43 mRNA by delaying the onset of mRNA degradation and that this process depends on the size of the poly(A) tail. Using a polysome-based in vitro mRNA decay ...
متن کاملPrenatal deletion of the RNA-binding protein HuD disrupts postnatal cortical circuit maturation and behavior.
The proper functions of cortical circuits are dependent upon both appropriate neuronal subtype specification and their maturation to receive appropriate signaling. These events establish a balanced circuit that is important for learning, memory, emotion, and complex motor behaviors. Recent research points to mRNA metabolism as a key regulator of this development and maturation process. Hu antig...
