The absence of Rab27a accelerates the degradation of Melanophilin

Melanophilin (Mlph) forms an interaction with Rab27a and the actin-based motor protein MyosinVa (MyoVa) on mature melanosome membranes and the tripartite complex regulates melanosome transport in melanocytes. In this study, we found that Rab27a siRNA decreased Mlph and Rab27a protein levels, but Mlph mRNA levels were not changed. Other Rab27a siRNA sequences also showed the same results. When Rab27a siRNA was treated with melan-a melanocytes,...
