Abstract

Non-insulin-dependent diabetes mellitus (NIDDM) is a multifactoral disease with both environmental and genetics causes. Genome-wide screening procedures have identified several susceptibility loci for NIDDM within the human genome. We describe the cloning of a putative sugar transporter that has been localized to human chromosome 20q12-q13.1, one of the genomic loci associated with NIDDM. Because of the strong resemblance of this novel protein to members of the mammalian facilitative glucose transporter family (GLUT), we refer to the protein as GLUT10 (HGMW-approved gene symbol SLC2A10). GLUT10 contains 541 amino acids with several glucose transporter sequence motifs and amino acids essential for glucose transport function. In addition, secondary structure analysis of GLUT10 predicts 12 putative transmembrane domains, a hallmark structure of the GLUT family. The tissue distribution of GLUT10 was determined by Northern analysis, which revealed highest levels of expression in the liver and pancreas. From these data, we believe that the chromosomal localization, tissue distribution, and predicted function make GLUT10 an excellent candidate for a susceptibility gene involved in NIDDM.
