General description

MLN64/StARD3 (also known as es64, StAR-related lipid transfer protein 3, Metastatic lymph node gene 64 protein, Metastatic lymph node protein 64, StARD3, START domain-containing protein 3, Steroidogenic acute regulatory protein related; UniProt Q14849) is encoded by the MLN64 (or CAB1 & STARD3) gene in human (NCBI Gene ID 10948). MLN64/StARD3 is a late endosome (LE) multitransmembrane protein that plays an important role in intracellular cholesterol transport and steroidogenesis. In addition to binding cholesterol via its C-terminal STAR domain, MLN64/StARD3 is reported to interact with ER-anchored VAP proteins via a conserved motif called "two phenylalanines in an acidic tract" or FFAT, thereby forming an LE-ER tethering complex at the inter-organelle membrane contacts sites (MCSs), allowing heterologous membrane apposition and the exchange of metabolites (PMID 23709693 and 24105263). Clone 2BE-2F4 is also known as 2BE2F4 and mAbMLN64-Ct, it detects an epitope within the c-terminal region encompassing the last 20% of MLN64 sequence.
