Reaction: IP6 is dephosphorylated to I(1,2,4,5,6)P5 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 1,2,3,4,5,6-hexakisphosphate (IP6) to inositol 1,2,4,5,6-pentakisphosphate (I(1,2,4,5,6)P5) (Caffrey et al. 1999, Chi et al. 1999, Deleu et al. 2006, Nogimori et al. 1991).
