    LMDRA (leucine rich melanocyte differentiation associated)

    Get PDF
    C10orf11 encodes a leucine-rich repeat protein having a role in melanocyte differentiation. Mutations in this gene have been associated with autosomal recessive oculocutaneous albinism 7 (OCAVII)

    SLC24A5 (solute carrier family 24 (sodium/potassium/calcium exchanger), member 5)

    Get PDF
    SLC24A5 is a member of the potassium-dependent sodium/calcium exchanger family and encodes an intracellular membrane protein. Sequence variations in this gene have been associated with differences in skin pigmentation, and the defective protein leads to Oculocutaneous albinism type VI, OCA6

    TYRP1 (tyrosinase-related protein 1)

    Get PDF
    TYRP1 gene, having a chromosomal location of 9p23, encodes a melanosomal enzyme belonging to the tyrosinase family. TYRP1 catalyses oxidation of 5,6-dihydroxyindole-2-carboxylic acid (DHICA) into indole-5,6-quinone-2-carboxylic acid. TYRP1 is also thought to play a role in stabilizing tyrosinase and modulates its catalytic activity, in maintenance of melanosome structure, affecting melanocyte proliferation and melanocyte cell death. Defects in this gene cause oculocutaneous albinism type III; OCA III (also known as rufous oculocutaneous albinism)

    SLC45A2 (solute carrier family 45 member 2)

    Get PDF
    SLC45A2 gene, having a chromosomal location 5p13.2, encodes a membrane associated transporter protein (MATP). MATP is a transmembrane protein. It is present in the melanosomal membrane in the melanocytes. It maintains the osmotic potential by regulating the pH of the melanosomal lumen. Defects in the SLC45A2 gene causes oculocutaneous albinism type IV; OCA I

    OCA2 (OCA2 melanosomal transmembrane protein)

    Get PDF
    OCA2 gene (OCA2), having a chromosomal location of 15q12-q13, encodes an integral membrane transporter protein playing a role in regulating the pH of melanosomes. OCA2 is hypothesized to be involved in the transport of tyrosine, the precursor to melanin synthesis, within the melanocyte. Defects in this gene are the cause of oculocutaneous albinism type II; OCA II

    Utilizing Reduced Graphene Oxide-Iron Nanoparticles Composite to Enhance and Accelerate the Removal of Methyl Blue Organic Dye in Wastewater

    In this work, a nano-composite is used to remove dye from wastewater of different industries. For this purpose, thesynthesis of a magnetic 1:1 composite made of iron nanoparticles (NPs) using reduced graphene oxide is a novel techniqueand tested for Methyl Blue (MB) dye adsorption from aqueous solution. In this study Fe nanoparticles in reduced Graphenecomposite (FGOC) has been prepared using Graphene Oxide (GO). X-ray diffraction, FTIR spectroscopy and Ramanspectroscopy, are used to identify the structures. Many methods have been developed for MB removal in wastewater. One ofthe most popular methods is adsorption because it is simple and high-efficiency, and the adsorbent is crucial. It reached amaximum MB adsorption at pH 7. The kinetic study indicated that the adsorption of MB process was fitted well to thequasi-first-order and quasi-second-order kinetic models. The isotherm study revealed that the MB adsorption process obeyedthe Langmuir and Freundlich adsorption Isotherms models. The GO adding content and absorption conditions on the methylblue removal efficiencies were investigated. This adsorbent is easily recovered by an external magnetic field from thetreated wastewater and has high reusability
