Gene: HMBS (hydroxymethylbilane synthase) Homo sapiens
Symbol: HMBS
Name: hydroxymethylbilane synthase
Description: Exhibits hydroxymethylbilane synthase activity. Predicted to be involved in heme biosynthetic process. Predicted to localize to cytoplasm. Implicated in acute intermittent porphyria and sickle cell anemia. Biomarker of prostate carcinoma; seminoma; and urinary bladder cancer.
Type: protein-coding
RefSeq Status: REVIEWED
