PLM a protein of the FXYD family of small ion transport regulators or channels. Induces a hyperpolarization-activated chloride current when expressed in Xenopus oocytes. May have a functional role in muscle contraction. Major plasma membrane substrate for PKA and PKC in several different tissues. Phosphorylated in response to insulin and adrenergic stimulation.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. Note: This description may include information from UniProtKB.
