  • Function

    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 chromophore for rhodopsin and the cone photopigments.
  • Tissue specificity

    Hepatic stellate cells and endothelial cells (at protein level). Found at high levels in testis and liver, followed by retinal pigment epithelium, small intestine, prostate, pancreas and colon. Low expression observed in brain. In fetal tissues, expressed in retinal pigment epithelium and liver, and barely in the brain.
  • Pathway

    Cofactor metabolism; retinol metabolism.
  • Involvement in disease

    Defects in LRAT are a cause of Leber congenital amaurosis type 14 (LCA14) [MIM:613341]. It is a severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus.
  • Sequence similarities

    Belongs to the H-rev107 family.
  • Cellular localization

    Endoplasmic reticulum membrane. Rough endoplasmic reticulum. Endosome > multivesicular body. Cytoplasm > perinuclear region. Present in the rough endoplasmic reticulum and multivesicular body in hepatic stellate cells. Present in the rough endoplasmic reticulum and perinuclear region in endothelial cells.

Vielen Dank für Ihre Anfrage.

Ich freue mich Ihnen bestätigen zu können, dass unsere Labor die folgende Antigendemaskierungsprozedur verwendet hat:

Antigen retrieval:

Steam slides in 0.01 M sodium citrate buffer, pH 6.0 at 99-100°C - 20 minutes
Remove from heat and let stand at room temperature in buffer - 20 minutes
Rinse in 1X TBS with Tween (TBST) – 1 minute at room temperature.

Als Lysispuffer im WB wurde standard RIPA Puffer eingesetzt, der 0.1% SDS enthaelt:

50 mM Tris HCl pH 8
150 mM NaCl
1% NP-40
0.5% sodium deoxycholate
0.1% SDS

The 10% sodium deoxycholate stock solution (5 g into 50 ml) must be protected from light.

The 100 mM EDTA stock solution is made with 1.86 g into 40 ml H2O and then add NaOH to dissolve and adjust pH to 7.4. Finally, adjust the total volume to 50 ml). Store the buffer at 4°C.

Ich hoffe, diese Information ist hilfreich und wünsche Ihnen viel Erfolg bei Ihren Versuchen.
