背景信息

The FMR1 gene, located on the X chromosome, encodes the fragile X mental retardation protein (FMRP), an RNA-binding protein critical for neuronal development, synaptic plasticity, and cognitive function. Mutations in FMR1. particularly a CGG triplet repeat expansion in the 5' untranslated region, are linked to fragile X syndrome (FXS), the most common inherited cause of intellectual disability. Full mutations (>200 CGG repeats) lead to gene silencing and loss of FMRP, disrupting mRNA translation, transport, and stability in neurons. Premutation carriers (55–200 repeats) may develop FMR1-related disorders, including fragile X-associated tremor/ataxia syndrome (FXTAS) and primary ovarian insufficiency (FXPOI), due to toxic RNA gain-of-function or reduced FMRP levels.

Recombinant FMR1 protein, produced via heterologous expression systems (e.g., bacterial, yeast, or mammalian cells), enables mechanistic studies of FMRP’s roles in neurodevelopment and disease. Its production allows large-scale analysis of FMRP’s structure, RNA/DNA-binding domains, and interactions with neuronal targets like ion channels and synaptic proteins. Researchers use recombinant FMRP to model FXS pathophysiology, screen therapeutic compounds, and develop protein replacement strategies. Challenges include preserving post-translational modifications (e.g., phosphorylation) critical for function and mimicking native cellular localization. Current studies focus on leveraging recombinant FMRP to restore neuronal translation regulation, correct synaptic defects, or target downstream pathways in FXS. Advances in protein engineering and delivery systems may enhance its therapeutic potential for fragile X-related disorders.
