That protein is one of the three MAT proteins and is called SERT.
Köhler, et al, studied karyopherin alpha in Saccharomyces cerevisiae, which is a protein of this class. Mutations in the SLC6A4 gene affected another protein in this class. That protein is one of the three MAT proteins and is called SERT. The SGLT one located in the Loop of Henle belongs to this class. Ion channels are another type of kind of this protein, which creates pores For 10 points, name this broad class of membrane proteins which helps in the movement of material, such as molecules, across a membrane, through facilitated diffusion or other means.
