O60760

功能描述

双功能酶,既催化PGH2转化为PGD2(一种参与平滑肌收缩/舒张的前列腺素,也是血小板聚集的强效抑制剂),也催化谷胱甘肽与多种芳基卤化物和有机异硫氰酸酯的结合。对枯烯过氧化氢亦表现出较低的谷胱甘肽过氧化物酶活性。 {ECO:0000269|PubMed:10824118, ECO:0000269|PubMed:11672424, ECO:0000269|PubMed:12244105, ECO:0000269|PubMed:12627223, ECO:0000269|PubMed:15113825, ECO:0000269|PubMed:16547010, ECO:0000269|PubMed:19939518, ECO:0000269|PubMed:9353279, ECO:0000269|PubMed:9425264}。

组织特异性

Expressed in a number of megakaryocytic cell lines but not in platelets. Highly expressed in adipose tissue, macrophages and placenta. Also expressed at lower levels in lung, heart, lymph nodes, appendix, bone marrow and fetal liver.
