Sarcolipin is a micropeptide protein that in humans is encoded by the SLN gene.^[3]^[4]

Function

Sarcoplasmic reticulum Ca²⁺-ATPases are transmembrane proteins that catalyze the ATP-dependent transport of Ca²⁺ from the cytosol into the lumen of the sarcoplasmic reticulum in muscle cells. The SLN gene encodes a small transmembrane proteolipid that regulates several sarcoplasmic reticulum Ca²⁺-ATPases by reducing the accumulation of Ca²⁺ in the sarcoplasmic reticulum without affecting the rate of ATP hydrolysis.^[4]

Ablation of sarcolipin increases atrial Ca²⁺ transient amplitudes and enhanced atrial contractility. Furthermore, atria from sarcolipin-null mice have blunted response to isoproterenol stimulation, implicating sarcolipin as a mediator of beta-adrenergic responses in atria.^[5]

Sarcolipin is an important mediator of muscle based non shivering thermogenesis (NST). It causes the sarcoplasmic reticulum Ca²⁺-ATPases to stop pumping Ca²⁺ ions but continue futilely hydrolysing ATP, thus releasing the energy as heat.^[6]^[7] Sarcolipin mediated heat production is very important for many organisms to maintain a warm body. In mammals thermogenesis by skeletal muscles is complemented by thermogenesis in the brown adipose tissue and beige adipose tissue. ^[8] Sarcolipin mediated heat production in contractile muscles helps endothermic fish like the opah heat its body. Some fishes like the billfishes have a specialised brain heater tissue that is derived from muscles that cannot contract but specialise in producing heat using sarcolipin.

Interactions

SLN (gene) has been shown to interact with PLN^[9]^[10] and ATP2A1.^[9]^[10]
