Phosphoinositides play a key role in signal transduction in the eukaryotic cell, transmitting signals from the cell surface to modulate intracellular processes. The 3-phosphoinositides, which contain the monophosphate phosphatidylinositol 3-phosphate, the bisphosphate phosphatidylinositol 3,4-bisphosphate and the trisphosphate phosphatidylinositol 3,4,5-trisphosphate, are particularly important in signaling cascades that influence a wide variety of cellular functions. These compounds are.generated by the action of several phosphatidylinositol 3-kinases (PI 3-kinases), as described in the pathway 3-phosphoinositide biosynthesis.
The levels of specific phosphoinositide pools are regulated by intricate networks of enzymes and proteins that govern the rates of phosphoinositide synthesis, transport, and degradation.
Phosphatidylinositol 3,4,5-trisphosphate is a transient plasma membrane signal, and is rapidly hydrolyzed by a 5-phosphatase reaction to phosphatidylinositol 3,4-bisphosphate or by a 3-phosphatase reaction to phosphatidylinositol 4,5-bisphosphate.
The 5-phosphatase reaction is catalyzed by several inositol polyphosphate 5-phosphatases that belong to groups type II (INPP5B, SYNJ1, SYNJ2, OCRL, INPP5K, INPP5F), type III (INPPL1, INPP5D) and type IV (INPP5E).
The 3-phosphatase reaction is catayzed by phosphatidylinositol-3,4,5-trisphosphate 3-phosphatas PTEN [Stephens93a, Mitchell02]. The importance of this reaction is made clear by the fact that mutations in this gene are found in a high percentage of human tumors, and particularly in glioblastoma, melanoma, and prostate and endometrial carcinomas [GinnPease03, Kurose02, Kanamori02, Frisk02, Mercapide02, Eng02, Staal02].
The bisphosphate products can also be degraded. Phosphatidylinositol 3,4-bisphosphate, an important second messenger on its own, is considered a more sustained signal, and lasts for up to 60 min before being hydrolyzed to form a 1-phosphatidyl-1D-myo-inositol 3-phosphate by the inositol polyphosphate 4-phosphatases (INPP4A and INPP4B) [Banfic98, Marshall02]. It can also be hydrolyzed by PTEN to form a 1-phosphatidyl-1D-myo-inositol 4-phosphate.
phosphatidylinositol 4,5-bisphosphate, is hydrolyzed by either 4-phosphatases (TMEM55A and TMEM55B) or the same 5-phosphatases listed above, resulting in a 1-phosphatidyl-1D-myo-inositol 5-phosphate or a 1-phosphatidyl-1D-myo-inositol 4-phosphate, respectively.
Finally, each of the monophosphates has been shown to be degraded by a specific enzyme, resulting in the formation of an L-1-phosphatidyl-inositol, which is recycled back to the membrane.

For each Arabidopsis sequence, the enzymatic activity of the top BLAST hit (or hits if they had equivalent E-values) was assigned to the protein if its E-value fell below a specific E-value threshold established for the corresponding enzymatic activity. Note: The annotation thresholds were established by doing a self BLAST of the reference enzyme dataset. For each enzymatic activity represented by multiple proteins, the mean E-value of all the correct hits generated by the self BLAST was selected as the cut-off. All of these means were averaged and used as the cut-off for assigning annotations for any enzymatic activities that were represented by a single protein in the reference dataset."
