该基因编码一种参与g蛋白丝裂原活化蛋白激酶（mapk）信号级联的蛋白。当该基因在哺乳动物细胞中过度表达时，可能会抑制ras和mapk介导的信号并干扰jnk活性，提示该基因的功能可能是信号抑制。编码蛋白是ncor1-hdac3（核受体辅加压素1-组蛋白脱乙酰基酶3）复合物的一个完整亚单位，研究表明，该复合物通过该亚单位抑制jnk的激活，从而可能为激素介导的ap1（活化蛋白1）功能拮抗提供一种替代机制。[由RefSeq提供，2008年7月]
This gene encodes a protein involved in G protein-mitogen-activated protein kinase (MAPK) signaling cascades. When overexpressed in mammalian cells, this gene could potently suppress a RAS- and MAPK-mediated signal and interfere with JNK activity, suggesting that the function of this gene may be signal repression. The encoded protein is an integral subunit of the NCOR1-HDAC3 (nuclear receptor corepressor 1-histone deacetylase 3) complex, and it was shown that the complex inhibits JNK activation through this subunit and thus could potentially provide an alternative mechanism for hormone-mediated antagonism of AP1 (activator protein 1) function.
