We have purified to homogeneity from the myofibrillar fraction of pig bladder a mammalian heterotrimeric form of PP-1, SMPP-1M. Purified pig bladder SMPP-1M is similar in composition and substrate specificity to avian gizzard PP-1M reported by Alessi et al. (Alessi, D., Macdougall, L. K., Sola, M.

A form of protein phosphatase-1 (PP1M), which possesses 25-fold higher activity towards the P light chain of myosin (in heavy meromyosin) than other forms of protein phosphatase-1, was purified over 200,000-fold from the myofibrillar fraction of rabbit skeletal muscle. PP1M, which eluted from

We have previously isolated a form of protein phosphatase-1 (PP1M) from avian smooth muscle myofibrils that is composed of the catalytic subunit of PP1 (PP1C) bound to an M-complex consisting of 110-kDa (M110) and 21-kDa (M21) subunits. The interaction of PP1C with an N-terminal region of the M110

A myosin phosphatase was purified from chicken gizzard smooth muscle. The holoenzyme is a trimer and consists of 130,000-, 38,000-, and 20,000-Da subunits (in agreement with the results of Alessi et al.: Alessi, D., MacDougall, L. K., Sola, M. M., Ikebe, M., and Cohen, P. (1992) Eur. J. Biochem.

Widespread expression of leptin and its receptor in developing cartilage and bone suggests that leptin may regulate bone growth and development in the fetus. Using microcomputed tomography, this study investigated the effects of exogenous leptin and leptin receptor antagonism on aspects of bone
