Retinoid fluxes and RE hydrolyzing enzymes. Depiction of major retinoid fluxes between tissues and organs, which are involved in the uptake, transport, storage, and utilization of retinoids. Identified REHs of respective organs, tissues, and cell types are given in parenthesis. REH activities of unidentified proteins are indicated as “?”. Percent of total bodies RE stores are given for major storage tissues and cell-types. Abbreviations: CEL, carboxylester lipase; Es2/3/4/10/22, esterase2/3/4/10/22; GS2, gene sequence 2; HSL, hormone-sensitive lipase; LPL, lipoprotein lipase; PLRP2, pancreatic lipase related protein 2; PTL, pancreatic triglyceride lipase; RPE65, retinal pigment epithelium 65.
