Status

Functioni

The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). Major enzyme required for hyperosmotic shock-induced turnover of PtdIns(3,5)P2 and requires VAC14 for this function. In vivo, mediates turnover of PtdIns(3,5)P2 at the vacuole membrane necessary for vacuolar size control. In vitro, catalyzes the removal of phosphate from the fifth hydroxyl of the myo-inositol ring of phosphatidylinositol 3,5-bisphosphate.4 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.
