MYBBP1A, NKRF, and MYPOP are transcription factors, mainly expressed in the nuclei, with tumor‐suppressing functions.[35, 36, 37, 38] We precipitated the nuclear F/G‐actin fractions in the Jasp‐, LatB‐, and CytD‐treated cells, and found that precipitation of nuclear F‐actin pulled down β‐catenin, SMAD2, and SMAD3, while precipitation of nuclear G‐actin pulled down MYBBP1A, NKRF and MYPOP (Figure 1E). Here, MYPOP is linked to neoplasm.
