Top Publications

  1. Yatsu A, Ohbayashi N, Tamura K, Fukuda M. Syntaxin-3 is required for melanosomal localization of Tyrp1 in melanocytes. J Invest Dermatol. 2013;133:2237-46 pubmed publisher
    ..These findings suggested that the SNARE machinery composed of VAMP7 on Tyrp1-containing vesicles and syntaxin-3 and SNAP23 on melanosomes regulates Tyrp1 trafficking to the melanosome in melanocytes. ..
  2. Kawasaki A, Kumasaka M, Satoh A, Suzuki M, Tamura K, Goto T, et al. Mitf contributes to melanosome distribution and melanophore dendricity. Pigment Cell Melanoma Res. 2008;21:56-62 pubmed publisher
    ..These results suggest that Mitf is involved in the regulation of melanosome transport and the level of dendricity in melanophores...
  3. Ohbayashi N, Mamishi S, Ishibashi K, Maruta Y, Pourakbari B, Tamizifar B, et al. Functional characterization of two RAB27A missense mutations found in Griscelli syndrome type 2. Pigment Cell Melanoma Res. 2010;23:365-74 pubmed publisher
    ..The Rab27A(K22R) mutant normally binds Munc13-4, but not Slp2-a or Slp4-a, whereas the Rab27A(I44T) mutant shows reduced binding activity to Slp2-a and Munc13-4 but normally binds Slp4-a. ..
  4. Tamura K, Ohbayashi N, Ishibashi K, Fukuda M. Structure-function analysis of VPS9-ankyrin-repeat protein (Varp) in the trafficking of tyrosinase-related protein 1 in melanocytes. J Biol Chem. 2011;286:7507-21 pubmed publisher
  5. Ohbayashi N, Maruta Y, Ishida M, Fukuda M. Melanoregulin regulates retrograde melanosome transport through interaction with the RILP-p150Glued complex in melanocytes. J Cell Sci. 2012;125:1508-18 pubmed publisher
    ..These findings reveal a new mechanism by which the dynein-dynactin motor complex recognizes Mreg on mature melanosomes through interaction with RILP and is involved in the centripetal movement of melanosomes. ..
  6. Matsui T, Ohbayashi N, Fukuda M. The Rab interacting lysosomal protein (RILP) homology domain functions as a novel effector domain for small GTPase Rab36: Rab36 regulates retrograde melanosome transport in melanocytes. J Biol Chem. 2012;287:28619-31 pubmed publisher
    ..Our findings indicated that Rab36 mediates retrograde melanosome transport in melanocytes through interaction with RILP. ..
  7. Ishida M, Ohbayashi N, Maruta Y, Ebata Y, Fukuda M. Functional involvement of Rab1A in microtubule-dependent anterograde melanosome transport in melanocytes. J Cell Sci. 2012;125:5177-87 pubmed publisher
    ..Taken together, these findings indicate that Rab1A is the first crucial component of the anterograde melanosome transport machinery to be identified in mammalian skin melanocytes. ..
  8. Ishida M, Arai S, Ohbayashi N, Fukuda M. The GTPase-deficient Rab27A(Q78L) mutant inhibits melanosome transport in melanocytes through trapping of Rab27A effector protein Slac2-a/melanophilin in their cytosol: development of a novel melanosome-targetinG tag. J Biol Chem. 2014;289:11059-67 pubmed publisher
    ..These findings indicate that the GTPase activity of Rab27A is required for its melanosome localization but is not required for melanosome transport. ..
  9. Marubashi S, Shimada H, Fukuda M, Ohbayashi N. RUTBC1 Functions as a GTPase-activating Protein for Rab32/38 and Regulates Melanogenic Enzyme Trafficking in Melanocytes. J Biol Chem. 2016;291:1427-40 pubmed publisher
    ..These results collectively indicate that proper spatiotemporal regulation of Rab32/38 is essential for the trafficking of all three melanogenic enzymes in mouse melanocytes. ..
