Tool Details


  • Name: Melan-rp4 cell line
  • Organism: Mouse
  • Tissue: Skin
  • Disease: Hermansky-Pudlak syndrome
  • Morphology: Small, oval-fusiform
  • Model: Immortalised non-cancerous cell lines
  • Description: The melan-rp3, -rp4 and -rp5 cell lines are immortal melanocyte cell lines derived from neonatal Rprp/Rprp Ink4aArf -/- mice. These cell lines lack Blos3, a subunit of the biogenesis of lysosome-related organelles complex 1 (BLOC-1). BLOC-1 is involved in cargo sorting from early-endosomes towards lysosome-related organelles, including melanosomes. Pathogenic variants in the human ortholog of Blos3 cause a form of Hermansky-Pudlak syndrome (HPS), HPS type 8. HPS is a group of disorders characterised by hypopigmentation, bleeding tendency and other variable symptoms. These cells are hypopigmented despite the expression of tyrosinase. These cells are a useful model for HPS and for the study of trafficking of cargoes towards lysosome-related organelles.
