    motifs/domains
  • N-terminal conserved membrane-spanning MENTAL (MLN64 NH(2)-terminal) domain shared with an unique protein called MENTHO (MLN64 NH(2)-terminal domain homologue) and targeting the protein to late endosome
  • one START domain, cholesterol-specific START domain [StAR (steroidogenic acute regulatory protein)-related lipid transfer domain]
  • C-terminal domain with a cholesterol binding steroidogenic acute regulatory-related lipid transfer domain exposed to the cytoplasm

    basic FUNCTION
  • late endosomal cholesterol-binding membrane protein that binds and transports cholesterol
  • promoting steroidogenesis in placenta and brain
  • may facilitate lutein localization to a region of the cell subject to considerable oxidative stress (
  • through the MENTAL domain, playing a role in maintaining cholesterol at the membrane of late endosomes prior to its shuttle to cytoplasmic acceptor(s)
  • acting as discrete cholesterol-containing subdomains within the membrane of late endosomes where they may function in cholesterol transport
  • involved in actin-mediated dynamics of late endocytic organelles
  • retinal lutein-binding protein

    protein
  • cholesterol, 25-hydroxycholesterol, phosphatidylcholine, phosphatidylethanolamine and ceramides are ligands for STAR/STARD3/STARD5, STARD5, PCTP/STARD10, STARD10 and COL4A3BP, respectively
  • differential cholesterol binding of the two most closely related START domain proteins STAR and STARD3
  • specific interactions of STARD3 with lutein
  • cell & other
    REGULATION
    induced by sterol depletion (methyl beta-cyclodextrin), enhancing STARD3, and represses STAR expression
