Protein

ATP-binding cassette sub-family A member 7

Gene

Abca7

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Plays a role in phagocytosis by macrophages of apoptotic cells. Binds APOA1 and may function in apolipoprotein-mediated phospholipid efflux from cells. May also mediate cholesterol efflux. May regulate cellular ceramide homeostasis during keratinocytes differentiation.3 Publications

Disruption phenotypei

According to PubMed:16908670, mice are not viable and heterozygous knockout mice display impaired phagocytosis of apoptotic cells. Depletion of Abca7 in macrophages by RNAi reduces phagocytosis of apoptotic cells. According to PubMed:15550377, mice are viable and females have less visceral fat and lower total serum and high density lipoprotein cholesterol level.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
