CMTM6 and neoplasm: If activated ROCK1 makes use of same set of regulators that are important for its established membrane blebbing and cytoskeletal ruffling function (Coleman et al, 2001) or some other mechanisms that potentially also include other regulators such as CMTM6 (Fig 4) to help mobilize PD‐L1 to tumor cell surface is beyond the scope of these investigations CMTM6 (Burr et al, 2017).
