SODIUM-INDEPENDENT TRANSPORTER TRANSPORTING SMALL-SIZED NEUTRAL AMINO ACID, GENE THEREOF AND METHOD OF ANALYZING TRANSPORTER FUNCTION BY CONSTRUCTING FUSED PROTEINS ENABLING THE SPECIFICATION OF THE FUNCTION

摘要

It is intended to provide a sodium-independent transporter which transports a small-sized neutral amino acid; its gene; fused proteins which enable the specification of the function thereof; and a method of analyzing the function of the transporter using the same. A protein having an amino acid sequence represented by SEQ ID NO: 1 which is capable of sodium-independently transporting a small sized neutral amino acid and its analog; a gene encoding the above protein; fused proteins of a protein having an amino acid sequence represented by SEQ ID NO:3 or 5 with the above-described protein; genes encoding the same; a method of analyzing the function of a transporter using the same; and its use.
