Phospholamban function
WebPhospholamban was first described as a cAMP-dependent protein kinase substrate in the early 1970s. The phosphorylated amino acid was shown to be Ser 16 and phosphorylation enhanced SERCA2a activity and Ca 2+ -uptake ( Kirchberger et al., 1972 ). WebPhospholamban is a 6-kDa protein that associates reversibly into pentamers. Phospholamban tonically inhibits the SERCA pump by increasing its Km for Ca 2+. Phosphorylation of phospholamban relieves this inhibition, speeding up the SR Ca-ATPase at any given [Ca 2+] and therefore lowering the cytoplasmic [Ca 2+ ].
