Ocular Albinism Type 1 - Structure of OA1 Protein

Structure of OA1 Protein

Human Oa1 gene product was initially identified as a 60kDa protein formed from a 46-48kDa precursor. The OA1 disease is due to defect in the OA1 receptor. This receptor has been shown to be similar to class C G- protein coupled receptors (GPCR). OA1 receptor has a characteristic GPCR structure-7 transmembrane helices with 3 cytoplasmic loops and 3 extracellular loops and an extracellular N- terminus and cytoplasmic C-terminus. Recently the ligand activating this receptor was found. A recent computational work has provided some insight into the three dimensional structure of this protein and its dynamic interactions with its known ligands.

    Just as a new scientific discovery manifests something that was already latent in the order of nature, and at the same time is logically related to the total structure of the existing science, so the new poem manifests something that was already latent in the order of words.
    Northrop Frye (b. 1912)

    Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.
    Paul Tillich (1886–1965)

    Firm-style bean curd insoles cushion feet, absorb perspiration and provide more protein than meat or fish innersoles of twice the weight. Tofu compresses with use, becoming more pungent and flavorful. May be removed when not in use to dry or marinate. Innersoles are ready to eat after 1,200 miles of wear. Each pair provides adult protein requirement for 2 meals. Insoles are sized large to allow for snacks. Recipe booklet included.
