CC -!- FUNCTION: ATP-dependent transporter of the ATP-binding cassette (ABC)
CC family that may be involved in the cellular efflux of sterols, in
CC particular cholesterol and desmosterol (a cholesterol precursor), to
CC high-density lipoprotein (HDL) (PubMed:15240127, PubMed:33141061). May
CC play an important role in the removal of amyloid-beta peptides from
CC brain, in a process that can be antagonized by desmosterol. However it
CC is unclear whether ABCG4 can directly transport amyloid-beta peptides
CC or whether peptide export may be facilitated due to changes in the
CC membrane lipid environment (By similarity). Induces apoptosis in
CC various cells (PubMed:27228027). {ECO:0000250|UniProtKB:Q91WA9,

CC status and cholesterol synthesis intermediates desmosterol, lathosterol
CC and lanosterol. {ECO:0000269|PubMed:33141061}.
CC -!- MISCELLANEOUS: Whether ABCG4 is an LXR target gene, is still under
CC debate. Studies performed in monocytes, and in one astrocyte cell line
CC indicated that ABCG4 expression could be up-regulated by oxysterols and
CC other LXR ligands (PubMed:11606068, PubMed:33141061). However,
CC subsequent observations in a number of different cell types (primary
CC mouse cells, oligodendrocytes and neuron-like cell lines) have not
CC confirmed this observation (By similarity) (PubMed:33141061).

CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. ABCG family.
