**Background of Recombinant Human MBNL3 Protein**
MBNL3 (Muscleblind-like protein 3) is a member of the conserved Muscleblind family of RNA-binding proteins, which play critical roles in regulating alternative splicing, mRNA localization, and stability. In humans, MBNL proteins (MBNL1-3) are essential for muscle and eye development, with dysfunctions linked to myotonic dystrophy (DM), a genetic disorder characterized by muscle wasting and multisystemic symptoms. MBNL3. though less studied than MBNL1/2. shares structural features including zinc finger domains that mediate interactions with RNA hairpins. It is implicated in cell differentiation, proliferation, and apoptosis, particularly in pluripotent stem cells and cancer.
Recombinant human MBNL3 protein is engineered using expression systems (e.g., *E. coli* or mammalian cells*) to enable functional studies. It retains RNA-binding activity, allowing researchers to investigate its role in splicing regulation, its competition with other splicing factors (e.g., CELF1), and its involvement in disease mechanisms. Production of recombinant MBNL3 facilitates *in vitro* assays, structural analyses, and therapeutic screenings aimed at modulating splicing anomalies in DM or other MBNL3-associated pathologies. Its study also contributes to understanding developmental biology and potential regenerative medicine applications.
