  • synthesized on the rough endoplasmic reticulum and subsequently transferred across the outer and inner membranes of mitochondria, a process requiring additional processing by peptidases and protection by chaperones for proper folding
  • basic FUNCTION
  • catalyzing the first step of porphyrin biosynthesis, pyridoxal dependent
  • rate-limiting enzyme in heme synthesis in the liver and is highly regulated to adapt to the metabolic demand of the hepatocyte (
  • first rate controlling enzyme that controls cellular heme biosynthesis

    small molecule cofactor,
  • pyridoxal phosphate
  • protein
  • interacting with STAMBP
  • direct target of the bile acid-activated nuclear receptor farnesoid X receptor (NR1H4)
  • hepatic ALAS1 is a new direct target for the nuclear receptor peroxisome proliferator-activated receptor alpha (PPARA)
  • interacting with LONP1 (a nuclearly encoded and mitochondrially located stress-responsive protease, that is involved in heme-mediated ALAS1 turnover)
