Rare mutations in the PLN gene have been identified with autism (Marshall et al., 2008).
Molecular Function
The encoded protein is an inhibitor of cardiac muscle sarcoplasmic reticulum Ca (2+)-ATPase in the unphosphorylated state, but inhibition is relieved upon phosp horylation of the protein.

Phospholamban acts as a critical repressor of basal myocardial contractility and may be the key phosphoprotein in mediating the heart's contractile responses to beta-adrenergic agonists.
