Previous HGNC Symbols for MRLN Gene
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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2015]

UniProtKB/Swiss-Prot for MRLN Gene
Inhibits the activity of ATP2A1/SERCA1 ATPase in sarcoplasmic reticulum by decreasing the apparent affinity of the ATPase for Ca(2+), thereby acting as a key regulator of skeletal muscle activity. Its high expression in adult skeletal muscle, suggests that it constitutes the predominant regulator of ATP2A1/SERCA1 in adult skeletal muscle.
