Phospholipase Cbeta1 (PLCbeta1) exists as two splice variants, PLCbeta1a (150 kDa) and PLCbeta1b (140 kDa), which differ only in their C-terminal sequences of 64 and 31 amino acids, respectively. The 3 C-terminal amino acid residues of PLCbeta1a comprise a PDZ-interacting domain, whereas the PLCbeta1b sequence has no PDZ-interacting domain but contains unique proline-rich domain 5 residues from the C terminus. PLCbeta1a is localized in the cytoplasm, whereas PLCbeta1b targets to the sarcolemma… CONTINUE READING
