This gene encodes a protein that contains a sterile alpha
motif domain in the N-terminus, an ATP/GTP-binding motif, a
GTPase-activating protein domain, and a STAR-related lipid transfer
domain in the C-terminus. The gene is located in a region of
chromosome 13 that has loss of heterozygosity in hepatic cancer. At
least three alternatively spliced transcript variants have been
described for this gene.
