NPC1L1 (NPC1 like intracellular cholesterol transporter 1)

Gene

• Entrez ID: 29881
• Gene name: NPC1 like intracellular cholesterol transporter 1
• Gene symbol: NPC1L1
• Synonyms (NCBI Gene): LDLCQ7, NPC11L1, SLC65A2
• Chromosome: 7
• Chromosome location: 7p13
• Summary: The protein encoded by this gene is a multi-pass membrane protein. It contains a conserved N-terminal Niemann-Pick C1 (NPC1) domain and a putative sterol-sensing domain (SSD) which includes a YQRL motif functioning as a plasma membrane to trans-Golgi netw
