Light-absorbing compositions and methods of use
The present disclosure relates to methods and compositions comprising naturally occurring light absorbing molecules for preventing damages from light exposure. Specific embodiments of this disclosure include fluorescent proteins from Brachiostoma lanceolatum.
1. A method for protecting the state of the skin from light damage in a subject in need thereof, in which said method comprises topically administering a composition comprising a dermatologically acceptable carrier or a vehicle and a functional Brachiostoma light absorbing protein polypeptide having SEQ ID No: 13 formulated for topical administration.
2. A method for protecting the state of the skin from light damage in a subject in need thereof, in which said method comprises topically administering a composition comprising a dermatologically acceptable carrier or a vehicle and a functional Brachiostoma light absorbing protein polypeptide having SEQ ID No: 14 formulated for topical administration.
3. The method of claim 1 wherein the Brachiostoma polypeptide is a derived from Brachiostoma floridae or Brachiostoma lanceolatum.
4. The method of claim 1 or 2 wherein said method comprises topically administering a composition comprising a dermatologically acceptable carrier or a vehicle and functional recombinant multimeric Brachiostoma light absorbing protein polypeptides formulated for topical administration comprising SEQ ID NO: 13 or SEQ ID NO: 14.
5. The method of claim 4 wherein the functional recombinant multimeric Brachiostoma light absorbing protein polypeptides formulated for topical administration comprises polypeptides that are tetramers, trimers or dimers.
6. The method of claim 5 wherein the functional recombinant Brachiostoma light absorbing protein polypeptides formulated for topical administration are tetramers.
7. The method of claims 1 or 2 wherein the recombinant multimeric protein is a heterotetrameric protein.
8. The method of anyone of claims 1 , 2 , or 3 wherein the method reduces UV-induced cellular damage.
