Facts about Phospholemman.
Associates with and Modulates the activity of This sodium/potassium-transporting ATPase (NKA) which transports Na(+) from the cell and K(+) into the cell.
Inhibits NKA activity in its unphosphorylated state and stimulates activity when phosphorylated.Reduce glutathionylation of the NKA beta-1 subunit ATP1B1, thus reversing glutathionylation-mediated inhibition of ATP1B1. Contributes to female sexual development by maintaining the excitability of neurons that secrete gonadotropin-releasing hormone.

Highest expression in skeletal muscle and heart. Moderate levels in brain, placenta, lung, liver, pancreas, uterus, bladder, prostate, small intestine and colon with mucosal lining. Very low levels in kidney, colon and small intestine without mucosa, prostate without endothelial lining, spleen, and testis.
Cell membrane, sarcolemma; Single-pass type I membrane protein. Apical cell membrane; Single-pass type I membrane protein. Membrane, caveola. Cell membrane, sarcolemma, T-tubule. Detected in the apical cell membrane in brain. In myocytes, localizes to sarcolemma, t-tubules and intercalated disks.
