Protein: Apolipoprotein B-100 (Apo B-100) [Cleaved into: Apolipoprotein B-48 (Apo B-48)] (E9Q414)
Organism: Mus musculus (Mouse)
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.
Subcellular location: Cytoplasm {ECO:0000250|UniProtKB:P04114}. Secreted {ECO:0000250|UniProtKB:P04114}. Lipid droplet {ECO:0000250|UniProtKB:P04114}.
