Mrln - myoregulin

This gene encodes a small peptide that shares structural similarity to the small peptides sarcolipin and phospholamban, which are key regulators of sarcoplasmic reticulum Ca(2+)-ATPases (SERCAs). This protein is thought to have a similar function to these peptides, regulating Ca(2+) reuptake in the sarcoplasmic reticulum by inhibiting the Ca(2+) pump activity of SERCAs.
