GO Classification
Functions
  • transferase activity, transferring acyl groups
  • cholesterol binding
  • fatty-acyl-CoA binding
  • cholesterol O-acyltransferase activity
Processes
  • cholesterol efflux
  • cholesterol homeostasis
  • cholesterol metabolic process
  • very-low-density lipoprotein particle assembly
  • intestinal cholesterol absorption
  • cholesterol esterification
  • macrophage derived foam cell differentiation
Components
  • endoplasmic reticulum
  • endoplasmic reticulum membrane
