STARD3 - StAR related lipid transfer domain containing 3 Gene
Also Known as CAB1; es64; MLN64
Species: Homo sapiens
About STARD3
This gene has 29 transcripts (splice variants), 212 orthologues and 5 paralogues. Ubiquitous expression in testis (RPKM 14.1), spleen (RPKM 13.2) and 25 other tissues.
Summary
This gene encodes a member of a subfamily of lipid trafficking proteins that are characterized by a C-terminal steroidogenic acute regulatory domain and an N-terminal metastatic lymph node 64 domain. The encoded protein localizes to the membranes of late endosomes and may be involved in exporting Cholesterol. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009]
