Phospholipid translocation seems also to be implicated in vesicle formation and in uptake of lipid signaling molecules. May be responsible for the maintenance of asymmetric distribution of phosphatidylserine (PS) in spermatozoa membranes. Involved in acrosome reactions and binding of spermatozoa to zona pellucida. {ECO:0000250|UniProtKB:Q6UQ17}. |HAD| |E1-E2 ATPase| |Hydrolase| |ATPase-coupled intramembrane lipid transporter activity| |acrosomal membrane| |binding of sperm to zona pellucida| |phospholipid translocation| |lipid translocation| |sperm-egg recognition| |regulation of membrane lipid distribution| |cell-cell recognition| |phospholipid transport| |organophosphate ester transport| |Golgi organization| |single fertilization| |fertilization| |magnesium ion binding| |cell recognition| |lipid transport| |lipid localization| |endomembrane system organization| |organic anion transport| |anion transport| |sexual reproduction| |membrane organization| |endoplasmic reticulum membrane| |Golgi apparatus| |multi-organism reproductive process| |ion transport| |reproductive process| |reproduction| |ATP binding| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp26|Oligomycin-A 20μM R00 exp26]]|-1.93| |[[:results:exp13|Chloramphenicol 20μM R00 exp13]]|-1.91| |[[:results:exp78|Pterostilbene 16μM R02 exp78]]|-1.75| |[[:results:exp235|Geldanamycin 0.01μM R05 exp235]]|1.7| |[[:results:exp345|Cidofovir 10μM R07 exp345]]|2.08| No correlation found to any other genes in chemogenomics.
