**Background of STBD1 Recombinant Protein**
Starch-binding domain 1 (STBD1), also known as genethonin-1. is a protein encoded by the *STBD1* gene in humans. It belongs to the carbohydrate-binding module 20 (CBM20) family, which is characterized by its ability to interact with starch and glycogen. STBD1 is primarily expressed in tissues involved in glucose metabolism, such as the liver and skeletal muscle, where it plays a role in glycogen trafficking and degradation.
Structurally, STBD1 contains a conserved N-terminal CBM20 domain responsible for binding polysaccharides like glycogen, and a C-terminal domain that facilitates interactions with autophagy-related proteins. Studies suggest that STBD1 acts as a mediator between glycogen particles and the autophagy machinery, promoting glycogen degradation via lysosomal pathways (a process termed "glycophagy"). This function links STBD1 to cellular energy homeostasis, particularly during fasting or metabolic stress.
Recombinant STBD1 protein is produced through genetic engineering techniques, often using bacterial (e.g., *E. coli*) or mammalian expression systems. The recombinant form retains the native protein's functional properties, enabling researchers to study its binding kinetics, structural features, and interactions with partners like laforin or AMP-activated protein kinase (AMPK). Its applications span *in vitro* assays, structural studies, and investigations into metabolic disorders.
Dysregulation of STBD1 has been implicated in glycogen storage diseases, type 2 diabetes, and obesity, making it a potential therapeutic target. Recombinant STBD1 tools are critical for elucidating its role in glycogen metabolism and developing strategies to modulate its activity in disease contexts.
