**Background of Recombinant Human NHLRC1 Protein**
NHLRC1 (NHL Repeat-Containing Protein 1), also known as E3 ubiquitin-protein ligase Malin, is a 395-amino-acid protein encoded by the *NHLRC1* gene. It contains an N-terminal RING finger domain and six NHL repeats, characteristic of proteins involved in substrate recognition and ubiquitination. NHLRC1 plays a critical role in glycogen metabolism and protein quality control, primarily by functioning as an E3 ubiquitin ligase in partnership with laforin, a phosphatase encoded by *EPM2A*. Together, they form a complex that regulates glycogen synthesis by targeting enzymes like glycogen synthase and protein phosphatase 1 (PP1) for ubiquitin-mediated degradation, ensuring proper glycogen structure and preventing aggregation.
Mutations in *NHLRC1* are linked to Lafora disease, a rare, fatal autosomal recessive neurodegenerative disorder characterized by progressive myoclonus epilepsy and cytoplasmic polyglucosan aggregates (Lafora bodies) in neurons. These aggregates result from abnormal glycogen phosphorylation and branching, leading to neuronal dysfunction. Recombinant NHLRC1 protein, produced via heterologous expression systems (e.g., *E. coli*, mammalian cells), is essential for studying its biochemical interactions, ubiquitination mechanisms, and pathological pathways in Lafora disease. It also serves as a potential therapeutic tool to restore NHLRC1 function or dissolve polyglucosan accumulations in experimental models. Research on recombinant NHLRC1 continues to advance understanding of glycogen regulation and neurodegeneration mechanisms.
