Identification of novel inhibitors of the amino acid transporter B0 AT1 (SLC6A19), a potential target to induce protein restriction and to treat type 2 diabetes.


ABSTRACT:

Background and purpose

The neutral amino acid transporter B0 AT1 (SLC6A19) has recently been identified as a possible target to treat type 2 diabetes and related disorders. B0 AT1 mediates the Na+ -dependent uptake of all neutral amino acids. For surface expression and catalytic activity, B0 AT1 requires coexpression of collectrin (TMEM27). In this study, we established tools to identify and evaluate novel inhibitors of B0 AT1.

Experimental approach

A CHO-based cell line was generated, stably expressing collectrin and B0 AT1. Using this cell line, a high-throughput screening assay was developed, which uses a fluorescent dye to detect depolarisation of the cell membrane during amino acid uptake via B0
