GENE ENCODING PROTEIN B

摘要

An objective of this invention is to identify and provide a gene encoding medaka protein B. An additional objective of the present invention is to provide human and murine homologues of the gene. To achieve the above mentioned objectives, the inventors performed positional cloning on the B gene. The gene encoding medaka protein B was successfully isolated, and the present invention has come to completion. Accordingly, in accordance with the invention, there are provided a nucleic acid encoding medaka protein B and those encoding homologues thereof. According to another aspect of the invention, there are provided a nucleic acid listed in Seq. No. 1 that encodes medaka protein B and a nucleic acid listed in Seq. No. 3 that encodes mouse protein B/AIM-1. According to the invention, there is provided a method of suppressing melanin production characterized in that expression of the gene encoding protein B is suppressed.
