Reaction: I(1,3,4,5,6)P5 is dephosphorylated to I(1,4,5,6)P4 by MINPP1 in the ER lumen
- in pathway: Synthesis of IPs in the ER lumen
In the endoplasmic reticulum (ER) lumen, multiple inositol polyphosphate phosphatase 1 (MINPP1) dephosphorylates inositol 1,3,4,5,6-pentakisphosphate (I(1,3,4,5,6)P5) to inositol 1,4,5,6-tetrakisphosphate (I(1,4,5,6)P4) (Caffrey et al. 1999, Chi et al. 1999).
