SLC45A4

The SLC45A4 gene encodes the solute carrier family 45 member 4 protein, a transmembrane transporter primarily expressed in pancreatic β-cells. It facilitates glucose uptake by regulating intracellular glucose transport, playing a critical role in glucose-stimulated insulin secretion. SLC45A4 interacts with the insulin signaling pathway, influencing β-cell function and glucose homeostasis.
Dysregulation of SLC45A4 is associated with type 2 diabetes mellitus, where impaired transporter activity contributes to β-cell dysfunction and insulin resistance. Emerging research highlights its potential as a therapeutic target; small-molecule modulators are being developed to enhance SLC45A4-mediated glucose uptake, aiming to improve insulin secretion in diabetic patients.
