Key regulator of protein phosphatase 1C (PPP1C). Mediates binding to myosin. As part of the PPP1C complex, involved in dephosphorylation of PLK1. Capable of inhibiting HIF1AN- dependent suppression of HIF1A activity
Tissue Specificity
Expressed in striated muscles, specifically in type 2a fibers (at protein level)
Cellular Localization
Cytoplasm. Note=Along actomyosin filaments and stress fibers
