Abstract
A complementary DNA encoding a novel human protein phosphatase 1 (PP1) glycogen-targetting subunit of molecular mass 33 kDa has been sequenced. PPP1R6 is 31% identical to the glycogen-targetting subunit (G(L)) of PP1 from rat liver, 28% identical to the N-terminal region of the glycogen-targetting subunit (G(M)) from human skeletal muscle and 27% identical to glycogen-targetting subunit PPP1R5. Unlike human PPP1R5 and its murine homologue PTG, whose mRNAs are most abundant in skeletal muscle, heart and liver, PPP1R6 is present at similar levels in a wide variety of tissues. The PPP1R6 is associated with glycogen in muscle but is not subject to the same modes of covalent and allosteric regulation as G(M) and G(L).
