Summary: Predicted to enable ABC-type xenobiotic transporter activity and lipid transporter activity. Predicted to be involved in several processes, including cholesterol efflux; positive regulation of cholesterol efflux; and sphingomyelin biosynthetic process. Predicted to act upstream of or within xenobiotic transmembrane transport. Located in basolateral plasma membrane. Is expressed in several structures, including alimentary system; eye; limb; male reproductive gland or organ; and nervous system. Orthologous to human ABCA8 (ATP binding cassette subfamily A member 8). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in liver E18 (RPKM 22.7), liver adult (RPKM 4.4) and 12 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
