title: Cloning of cDNA encoding rat phospholipase C-beta 4, a new member of the phospholipase C.
abstract: Phospholipase C-beta 4(PLC-beta 4), a new member of phospholipase C isozyme, was purified from bovine cerebellum. The cDNA encoding rat PLC-beta 4 has been cloned from a cDNA library prepared from rat brain. The predicted open reading frame encodes a protein of 1,176 amino acids with a calculated molecular weight of 134,552. The deduced amino acid sequence exhibits 39, 36, and 36% identity with the sequences of rat PLC-beta 1, human PLC-beta 2, and rat PLC-beta 3, respectively. The amino acid sequence of PLC-beta 4, especially, shows higher identity (50%) with norpA PLC sequence from Drosophila melanogaster than those of other PLC-beta subtypes, suggesting that the PLC-beta 4 might be a mammalian PLC equivalent of norpA PLC implicated in photosignal transduction in Drosophila.
