PA1-25784 detects Phospholamban (phospho S16) from human, canine, mouse, rabbit, rat, porcine and bovine samples. PA1-25784 is expected to cross react with rabbit, mouse, rat, canine, and porcine due to sequence homology.
PA1-25784 has been successfully used in Western blot procedures.
The PA1-25784 immunogen is a synthetic peptide, KLH-conjugated, corresponding to residues R(14) A [pS] T I E M P Q Q A R(25) C of human cardiac phospholamban. The immunizing sequence is conserved in mouse, rat, rabbit, pig and dog.
Store product as a concentrated solution. Centrifuge briefly prior to opening the vial. For short-term storage (1-2 weeks), product can be stored at 4°C. For long-term storage, aliquot and store product at -20° C or below, avioiding multiple freeze-thaw cycles.
Phospholamban (PLB) is a 52 amino acid phosphoprotein which regulates the calcium pump of cardiac sarcoplasmic reticulum (SR). PLB is an oligomer of five identical subunits each having a cytoplasmic and transmembrane domain. The cytoplasmic domain (residues 1 to 25) contains the phosphorylation sites and is highly basic and readily cleaved by proteases; whereas the transmembrane domain (residues 25 to 52) is mostly hydrophobic, protease resistant and stabilizes the pentamer. Following adrenergic stimulation of cardiac muscle, PLB is phosphorylated at Ser16 and at Thr17 which is correlated with stimulation of calcium transport activity across the SR membrane and relaxation of cardiac fibers.
