Human acetyl-coA cholesterol acyltransferase (ACAT1) gene produces a chimeric mRNA through the interchromosomal processing of two discontinuous RNAs transcribed from chromosomes 1 and 7. This chimeric mRNA uses AUG as a translation initiation codon to produce the normal 50-kDa ACAT1 protein but used an alternative translation initiation codon, GGC, to produce the novel enzymatically active 56-kDa isoform.
