Summary
This gene product is the main apolipoprotein of chylomicrons and low density lipoproteins. It occurs in plasma as two main isoforms, apoB-48 and apoB-100. Unlike the apoB-48 and apoB-100 structural equivalents in human, which are synthesized exclusively in the gut and liver, respectively, the mouse apoB-48 isoform is also found in mouse liver. The intestinal and the hepatic forms of apoB are encoded by a single gene from a single, very long mRNA. The two isoforms share a common N-terminal sequence. The shorter apoB-48 protein is produced after RNA editing of the apoB-100 transcript at residue 2179 (CAA->UAA), resulting in the creation of a stop codon, and early translation termination.

Comments

Comment Type Description
Function Apolipoprotein B is a major protein constituent of chylomicrons (apo B-48), LDL (apo B-100) and VLDL (apo B-100). Apo B-100 functions as a recognition signal for the cellular binding and internalization of LDL particles by the apoB/E receptor.
Ptm Palmitoylated; structural requirement for proper assembly of the hydrophobic core of the lipoprotein particle. {ECO:0000250}.
Rna Editing Modified_positions=2179; Note=The stop codon (UAA) at position 2179 is created by RNA editing. Apo B-48, derived from the fully edited RNA, is produced only in the intestine and is found in chylomicrons. Apo B-48 is a shortened form of apo B-100 which lacks the LDL-receptor region. The unedited version (apo B- 100) is produced by the liver and is found in the VLDL and LDL (By similarity). {ECO:0000250};
Sequence Caution Sequence=AAI41358.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=AAI41361.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=BAE27983.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
Similarity Contains 1 vitellogenin domain. {ECO:0000255|PROSITE- ProRule:PRU00557}.
Subcellular Location Cytoplasm {ECO:0000250}. Secreted {ECO:0000250}.
Subunit Interacts with PCSK9. {ECO:0000250}.
