Abstract:
The Solute Carrier Family 27 Member 1 (SLC27A1) is an evolutionarily conserved protein involved in regulating the long chain fatty acid uptake into cells. It has been shown to be expressed in tissues undergoing rapid fatty acid metabolism such as heart, skeletal muscle and adipose tissues, but no expression is detected in liver. Here we report the molecular characterization of the bovine SLC27A1 gene and draw a comparison with orthologous genes of some monogastric species. The bovine SLC27A1 gene is organized in 13 exons and extends over more than 40 kb of genomic DNA. It codes for a protein of 646 amino acids with a predicted molecular weight of 71 kDa which has 92%, 88% and 88% similarity with the human, mouse and rat SLC27A1 proteins respectively. The bovine SLC27A1 RNA expression was high in heart, testis, nervous tissue and muscle and very low in liver. Surprisingly, adipose tissues showed very low RNA expression levels contrary to the results described for both human and mouse genes. On the other hand, discordances observed between the bovine SLC27A1 RNA and protein expression patterns suggest that complex regulation mechanisms may be involved in determining the final SLC27A1 protein levels in each tissue. Finally, we have identified an alternative transcript generated by exon skipping of exon 3 to 7 which could encode a cytosolic SLC27A1 isoform of approximately 37 kDa.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Membrane Transporters
Transporters are mainly composed of alpha-helices, built from bundles of ten or more helices traversing the plasma membrane. The solute-binding sites are located midway, where some of the helices are broken or distorted, making space for the binding site through...
