Sodium-independent transporter that transports small neutral amino acids and its gene, and a method for analyzing the function of the transporter by creating a fusion protein that makes it possible to specify its function

摘要

The present invention provides a sodium-independent transporter that transports a small neutral amino acid and its gene, a fusion protein that makes it possible to specify its function, and a method for analyzing the function of the transporter using the same. The present invention relates to a protein having the ability to transport a small neutral amino acid having the amino acid sequence shown by SEQ ID NO: 1 and its analogs in a sodium-independent manner, and a gene encoding the protein. The present invention also relates to a fusion protein of a protein having the amino acid sequence represented by SEQ ID NO: 3 or 5 and the above protein, a gene encoding the same, a method for analyzing the function of a transporter using the same, and use thereof.
