Myosin Phosphatase Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

The major protein phosphatase-1 (PP1) is composed of 3 subunits with apparent molecular mass of 110-130, 37 & 20 kDa. The 110-130 kDa component act as a regulatory subunit known as myosine binding (MBS) or myosine phosphatae targeting subunit (MYPT). The N-terminal portion of MYPT binds to both PP1c-delta and phosphorylated myosin, thereby increasing myosin phosphatase activity. Two isoform of MYPT have been identified (MYPT1 & MYPT2) and share 61% sequence identity. While MYPT1 is widely distributed in human tissues, MYPT2 is mostly detected in brain and heart.
