APOBEC1 (Apolipoprotein B mRNA Editing Enzyme, Catalytic Polypeptide 1): APOBEC1 is an RNA-editing enzyme primarily involved in the post-transcriptional modification of apolipoprotein B (apoB) mRNA, leading to the production of a shorter apoB protein form in the intestine. This modification is crucial for lipid metabolism and plays a role in the assembly and secretion of lipoproteins. Dysregulation of APOBEC1 can affect cholesterol homeostasis and is of interest in studies related to cardiovascular diseases and lipid disorders....
