MYLPF (Myosin Light Chain Phosphatase regulatory subunit F), also known as myosin phosphatase target subunit 1 (MYPT1), is a critical regulatory component of the myosin light chain phosphatase (MLCP) complex. This protein plays a central role in modulating smooth muscle contraction and non-muscle cell motility by regulating the dephosphorylation of myosin light chain (MLC), a process essential for actin-myosin interaction. MYLPF acts as a scaffold that binds the catalytic subunit of protein phosphatase 1 (PP1c) and myosin, enabling targeted dephosphorylation of MLC to promote muscle relaxation or reduce contractile force.
Structurally, MYLPF contains conserved domains such as the N-terminal PP1c-binding motif, central coiled-coil regions for dimerization, and C-terminal sequences for myosin interaction. Its activity is tightly regulated by post-translational modifications, including phosphorylation by Rho-associated kinase (ROCK) and other kinases, which inhibit MLCP function and enhance myosin activation. Dysregulation of MYLPF has been implicated in cardiovascular diseases (e.g., hypertension, atherosclerosis), cancer metastasis (via altered cell migration), and neurological disorders.
Recombinant MYLPF proteins are widely used to study MLCP signaling mechanisms, screen therapeutic compounds targeting muscle hypercontractility, and model disease-related mutations. Produced in bacterial or mammalian expression systems, these proteins retain functional domains for biochemical assays, structural studies, and drug discovery. However, challenges in maintaining solubility and post-translational modification fidelity necessitate optimization of expression conditions. Current research leverages recombinant MYLPF to dissect its role in cytoskeletal dynamics and develop precision therapies for conditions linked to MLCP dysregulation.
