Phostensin, Protein phosphatase 1 F-actin cytoskeleton-targeting subunit, Protein phosphatase 1 regulatory subunit 18, PPP1R18, HKMT1098, KIAA1949
PHTNS interacts with regulatory subunits that target the enzyme to different cellular locations and change its activity toward specific substrates. Phostensin is a regulatory subunit that targets PP1 to F-actin cytoskeleton
