蛋白质信息 (UniProt)

丝氨酸/苏氨酸蛋白激酶pim-3 (EC 2.7.11.1)

Q86V86

功能描述

具有丝氨酸/苏氨酸激酶活性的原癌基因,可阻止细胞凋亡,促进细胞存活和蛋白质翻译。可能通过以下途径促进肿瘤发生:通过磷酸化BAD传递存活信号从而诱导抗凋亡蛋白Bcl-X(L)的释放,调节细胞周期进程、蛋白质合成以及调节MYC转录活性。除了在肿瘤发生中的作用外,还可以通过SOCS6抑制MAPK1/3 (ERK1/2)的激活,从而负向调节胰岛素分泌。还参与能量代谢的控制以及调节AMPK活性,以调控MYC和PPARGC1A蛋白水平及细胞生长。 {ECO:0000269|PubMed:15540201, ECO:0000269|PubMed:16818649, ECO:0000269|PubMed:17270021, ECO:0000269|PubMed:17876606, ECO:0000269|PubMed:18593906}.

组织特异性

Detected in various tissues, including the heart, brain, lung, kidney, spleen, placenta, skeletal muscle, and peripheral blood leukocytes. Not found or barely expressed in the normal adult endoderm-derived organs such as colon, thymus, liver, or small intestine. However, expression is augmented in premalignant and malignant lesions of these organs.
