蛋白质信息 (UniProt)

Ras GTP酶激活样蛋白IQGAP1 (p195)

P46940

功能描述

在调节肌动蛋白细胞骨架的动力学和组装中发挥关键作用。通过与ILK相互作用被招募至细胞皮层,使其能与效应因子DIAPH1协作,局部稳定微管并允许小窝稳定插入质膜 (By similarity)。结合活化的CDC42,但不刺激其GTPase活性。与钙调蛋白结合。可能促进神经突生长 (PubMed:15695813)。可能通过促进DNA复制阻滞后的细胞周期进程,在细胞周期调节中发挥潜在作用 (PubMed:20883816)。 {ECO:0000250|UniProtKB:Q9JKF1, ECO:0000269|PubMed:15695813, ECO:0000269|PubMed:20883816}.

组织特异性

Expressed in the placenta, lung, and kidney (PubMed:8051149). A lower level expression is seen in the heart, liver, skeletal muscle and pancreas (PubMed:8051149).
