Sarcolipin (SLN) is a small transmembrane protein predominantly expressed in skeletal and cardiac muscle tissues. It was first identified in the late 1990s as a regulator of sarco/endoplasmic reticulum Ca²⁺-ATPase (SERCA), a critical pump responsible for calcium reuptake into the sarcoplasmic reticulum during muscle relaxation. SLN binds to SERCA, modulating its activity by reducing calcium transport efficiency, which influences cellular energy expenditure and heat production. This unique role positioned SLN as a key player in non-shivering thermogenesis and metabolic regulation, particularly in skeletal muscle.
The discovery of SLN's involvement in adaptive thermogenesis sparked interest in its potential applications for metabolic diseases. Studies revealed that SLN overexpression increases energy expenditure, suggesting a link to obesity resistance and metabolic health. However, its physiological relevance in humans remained debated until recent research highlighted its expression in human skeletal muscle and its regulatory effects on SERCA isoforms.
Recombinant SLN protein production emerged as a tool to study its structure-function relationships and therapeutic potential. Using expression systems like *E. coli* or mammalian cells, researchers produce purified SLN for biochemical assays, structural studies (e.g., NMR or crystallography), and functional experiments. These efforts clarified how SLN interacts with SERCA and identified mutations affecting muscle disorders like Brody myopathy.
Current research focuses on leveraging recombinant SLN to develop strategies for enhancing energy expenditure in metabolic syndromes. Challenges include optimizing stable protein yields and elucidating tissue-specific regulatory mechanisms. As a naturally occurring metabolic modulator, SLN continues to offer insights into muscle physiology and precision therapeutics for energy imbalance disorders.
