Phosphatase Classification: Fold CC1: Superfamily CC1: Family Sac
The Sac family has four subfamilies:
- SAC1 - an integral membrane phosphoinositide phosphatase located in endoplasmic reticulum (ER) and golgi apparatus. Its substrate in vivo is phosphatidylinositol 4-phosphate (PtdIns4P), and it is also able to dephosphorylate other phosphoinositides in vitro. SAC1 is conserved in eukaryotes.
- INPP5F (SAC2) - a phosphoinositide phosphatase in the endocytic pathway. It is conserved in metazoa and fungi and is also found in a few plants and basal eukaryotes.
- FIG4 (SAC3) - a phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2) phosphatase located in the vacuolar membrane. It is associated with a form of Charcot-Marie-Tooth disorder CMT4J, Yunis-Varón syndrome, and amyotrophic lateral sclerosis (ALS). FIG4 is found in most if not all eukaryotes.
- Synaptojanin - a PtdIns(3,5)P2 phosphatase in the endocytic pathway. It has two phosphatase domains dephosphorylate 3-position and 5-position of PtdIns(3,5)P2, respectively. It is conserved in
