SCAP (SREBF chaperone)

Gene

• Entrez ID: 22937
• Gene name: SREBF chaperone
• Gene symbol: SCAP
• Synonyms: -
• Chromosome: 3
• Chromosome location: 3p21.31
• Summary: This gene encodes a protein with a sterol sensing domain (SSD) and seven WD domains. In the presence of cholesterol, this protein binds to sterol regulatory element binding proteins (SREBPs) and mediates their transport from the ER to the Golgi. The SREBP
