該基因編碼的蛋白是絲氨酸/蘇氨酸激酶，是一些信號轉導通路的一部分，包括erk和jnk激酶途徑以及nf-kappa-b途徑。編碼的蛋白質被自磷酸化激活，需要鎂作為其他蛋白質磷酸化的輔助因子。該蛋白具有e3連接酶活性，由植物同源結構域（phd）賦予其n-末端，磷酸激酶活性由激酶結構域賦予其c-末端。[由RefSeq提供，2012年3月]
The protein encoded by this gene is a serine/threonine kinase and is part of some signal transduction cascades, including the ERK and JNK kinase pathways as well as the NF-kappa-B pathway. The encoded protein is activated by autophosphorylation and requires magnesium as a cofactor in phosphorylating other proteins. This protein has E3 ligase activity conferred by a plant homeodomain (PHD) in its N-terminus and phospho-kinase activity conferred by a kinase domain in its C-terminus. [provided by RefSeq, Mar 2012]
