Summary
Enables 5-aminolevulinate synthase activity. Involved in erythrocyte differentiation; heme biosynthetic process; and hemoglobin biosynthetic process. Acts upstream of or within intracellular iron ion homeostasis. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and liver and biliary system. Human ortholog(s) of this gene implicated in cutaneous porphyria; erythropoietic protoporphyria; hemochromatosis; sideroblastic anemia; and sideroblastic anemia 1. Orthologous to human ALAS2 (5'-aminolevulinate synthase 2). [provided by Alliance of Genome Resources, Nov 2024]

  10. Data suggest the reaction of glycine with ALAS follows a three-step kinetic process, and the substrate 5-aminolevulinate induces a conformational change in ALAS which may modulate product release.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
