ATP9A

ATP9A (ATPase Phospholipid Transporting 9A (Putative)) is a Protein Coding gene. Among its related pathways are Ion channel transport and Cardiac conduction. Gene Ontology (GO) annotations related to this gene include nucleotide binding and cation-transpo

ATPase, class II, type 9A

Plays a role in regulating membrane trafficking of cargo proteins, namely endosome to plasma membrane recycling and endosome to trans-Golgi network retrograde transport (PubMed:27733620, PubMed:30213940).
In complex with MON2 and DOP1B, regulates SNX3 retromer-mediated endosomal sorting of WLS, a transporter of Wnt morphogens in developing tissues. Participates in the formation of endosomal carriers that direct WLS trafficking back to Golgi, away from lysosomal degradation (PubMed:30213940).
Appears to be implicated in intercellular communication by negatively regulating the release of exosomes (PubMed:30947313).
The flippase activity towards membrane lipids and its role in membrane asymmetry remains to be proved (PubMed:30947313).
