(1995) identified and characterized a previously unreported human gene located within the previously known cluster of apolipoprotein genes on chromosome 19: APOE, APOC1, and APOC2.
On the basis of its location and its properties, the new gene was designated APOC4.
Nucleotide sequence analysis of genomic DNA and liver cDNA clones revealed a 3.3-kb gene consisting of 3 exons and 2 introns.
Its 3-prime terminus lies 555 bp upstream of APOC2, giving the 2 genes the same transcriptional orientation.
The promoter of the APOC4 lacks a typical TATA box, consistent with an apparent heterogeneity in transcription start sites.
RNase protection analysis indicated relatively low apoC-IV mRNA levels in human liver, compared to apoC-II mRNA levels.
