Summation

Type II inositol-1,4,5-trisphosphate 5-phosphatase (INPP5B) is attached to the plasma membrane where it dephosphorylates inositol 1,3,4,5-tetrakisphosphate (I(1,3,4,5)P4) to inositol 1,3,4-trisphosphate (I(1,3,4)P3 (Jefferson & Majerus 1995, Ross et al. 1991, Schmid et al. 2004). INPP5B is isoprenylated at its C-terminus for membrane attachment.
