WebThe C-to-U editing of apolipoprotein B (apo-B) mRNA is catalyzed by a multiprotein complex that recognizes an 11-nucleotide mooring sequence downstream of the editing site. The catalytic subunit of the editing enzyme, apobec-1, has cytidine deaminase activity but requires additional unidentified proteins to edit apo-B mRNA. WebThis gene encodes a member of the cytidine deaminase enzyme family. The encoded protein forms a multiple-protein editing holoenzyme with APOBEC1 complementation factor and APOBEC1 stimulating protein . This holoenzyme is involved in the editing of C-to-U nucleotide bases in apolipoprotein B and neurofibromatosis-1 mRNAs. Synonyms

"Apolipoprotein B mRNA editing enzyme, catalytic polypeptide 1 also known as C->U-editing enzyme APOBEC-1 is a protein that in humans is encoded by the APOBEC1 gene. This gene encodes a member of the APOBEC protein family and the cytidine deaminase enzyme family. The encoded protein forms a multiple … See more APOBEC1 lies on human chromosome 12. See more A1 modifies the cytosine base at position 6666 on the ApoB mRNA strand through a deamination. An A1 dimer first binds to ACF, which forms the binding complex that is then able to … See more The low levels of A1 in humans are one reason why high lipid intake is damaging to health. ApoB48 is essential for the assembly and secretion of triglyceride-rich chylomicrons, which are necessary as a response to high-fat intake.
