Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Size

RPE65retinal pigment epithelium-specific protein 65kDa; Plays important roles in the production of 11-cis retinal and in visual pigment regeneration. The soluble form binds vitamin A (all-trans-retinol), making it available for LRAT processing to all-trans-retinyl ester. The membrane form, palmitoylated by LRAT, binds all-trans-retinyl esters, making them available for IMH (isomerohydrolase) processing to all-cis- retinol. The soluble form is regenerated by transferring its palmitoyl groups onto 11-cis-retinol, a reaction catalyzed by LRAT. The enzymatic activity is linearly dependent of th [...] (533 aa)
ADH4alcohol dehydrogenase 4 (class II), pi polypeptide (380 aa)
RDH12retinol dehydrogenase 12 (all-trans/9-cis/11-cis); Exhibits an oxidoreductive catalytic activity towards retinoids. Most efficient as an NADPH-dependent retinal reductase. Displays high activity toward 9-cis and all-trans-retinol. Also involved in the metabolism of short-chain aldehydes. No steroid dehydrogenase activity detected. Might be the key enzyme in the formation of 11-cis-retinal from 11-cis-retinol during regeneration of the cone visual pigments (316 aa)
RETSATretinol saturase (all-trans-retinol 13,14-reductase); Retinol saturase carrying out the saturation of the 13- 14 double bond of all-trans-retinol to produce all-trans-13,14- dihydroretinol. Has activity toward all-trans-retinol as substrate. Does not use all-trans-retinoic acid nor 9-cis, 11-cis or 13-cis-retinol isomers as substrates. May play a role in the metabolism of vitamin A (By similarity) (610 aa)
ADH5alcohol dehydrogenase 5 (class III), chi polypeptide; Class-III ADH is remarkably ineffective in oxidizing ethanol, but it readily catalyzes the oxidation of long-chain primary alcohols and the oxidation of S-(hydroxymethyl) glutathione (374 aa)
ADH1Balcohol dehydrogenase 1B (class I), beta polypeptide (375 aa)
SDR16C5short chain dehydrogenase/reductase family 16C, member 5; Oxidoreductase with strong preference for NAD. Active in both the oxidative and reductive directions. Oxidizes all-trans- retinol in all-trans-retinaldehyde. No activity was detected with 11-cis-retinol or 11-cis-retinaldehyde as substrates with either NAD(+)/NADH or NADP(+)/NADPH (309 aa)
DHRS9dehydrogenase/reductase (SDR family) member 9; 3-alpha-hydroxysteroid dehydrogenase that converts 3- alpha-tetrahydroprogesterone (allopregnanolone) to dihydroxyprogesterone and 3-alpha-androstanediol to dihydroxyprogesterone. May play a role in the biosynthesis of retinoic acid from retinaldehyde, but seems to have low activity with retinoids. Can utilize both NADH and NADPH (319 aa)

DHRS4L2dehydrogenase/reductase (SDR family) member 4 like 2; Probable oxidoreductase (By similarity) (232 aa)
LRATlecithin retinol acyltransferase (phosphatidylcholine--retinol O-acyltransferase); Transfers the acyl group from the sn-1 position of phosphatidylcholine to all-trans retinol, producing all-trans retinyl esters. Retinyl esters are storage forms of vitamin A. LRAT plays a critical role in vision. It provides the all-trans retinyl ester substrates for the isomerohydrolase which processes the esters into 11-cis-retinol in the retinal pigment epithelium; due to a membrane-associated alcohol dehydrogenase, 11 cis-retinol is oxidized and converted into 11-cis-retinaldehyde which is the chrom [...] (230 aa)
APOA4apolipoprotein A-IV; May have a role in chylomicrons and VLDL secretion and catabolism. Required for efficient activation of lipoprotein lipase by ApoC-II; potent activator of LCAT. Apoa-IV is a major component of HDL and chylomicrons (396 aa)
AKR1B10aldo-keto reductase family 1, member B10 (aldose reductase); Acts as all-trans-retinaldehyde reductase.

Can also catalyze the reverse reaction (317 aa)
ADH7alcohol dehydrogenase 7 (class IV), mu or sigma polypeptide; Could function in retinol oxidation for the synthesis of retinoic acid, a hormone important for cellular differentiation. Medium-chain (octanol) and aromatic (m-nitrobenzaldehyde) compounds are the best substrates. Ethanol is not a good substrate but at the high ethanol concentrations reached in the digestive tract, it plays a role in the ethanol oxidation and contributes to the first pass ethanol metabolism (394 aa)
