WebJun 26, 2024 · A family of facilitative glucose transporters (GLUTs) is involved in regulating tissue-specific glucose uptake and metabolism in the liver, skeletal muscle, and adipose … WebGLUT4 (SLC2A4) is the insulin-responding glucose transporter, found predominantly in muscle cells and adipocytes (fat cells). After a meal, glucose that is absorbed from the digestive system and circulates in the blood now stimulates the release of insulin from the pancreas (Figure 4.10).This insulin is the signal for a rapid transfer of GLUT4 in muscle …
