這個基因編碼血紅素生物合成途徑中的一種酶。這種酶通過去除四個羧甲基側鏈來催化尿卟啉原轉化為糞卟啉原。已知這種酶的突變和缺乏會導致家族性遲發性皮膚卟啉癥和肝紅細胞性卟啉癥。
This gene encodes an enzyme in the heme biosynthetic pathway. This enzyme is responsible for catalyzing the conversion of uroporphyrinogen to coproporphyrinogen through the removal of four carboxymethyl side chains. Mutations and deficiency in this enzyme are known to cause familial porphyria cutanea tarda and hepatoerythropoetic porphyria.
