AKAP9（A-kinase anchoring protein 9），癌症关联基因，基因ID：10142，A激酶锚定蛋白（AKAPs）是一类结构多样的蛋白质，具有与蛋白激酶A（PKA）调节亚单位结合和将全酶限制在细胞内离散位置的共同功能这个基因编码一个akap家族的成员。该基因的交替剪接导致至少两种亚型定位于中心体和高尔基体，并与来自多种信号转导途径的许多信号蛋白相互作用。这些信号蛋白包括Ⅱ型蛋白激酶a、丝氨酸/苏氨酸激酶蛋白激酶n、蛋白磷酸酶1、蛋白磷酸酶2a、蛋白激酶c-ε和磷酸二酯酶4d3。[由RefSeq提供，2008年8月]The A-kinase anchor proteins (AKAPs) are a group of structurally diverse proteins which have the common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the holoenzyme to discrete locations within the cell. This gene encodes a member of the AKAP family. Alternate splicing of this gene results in at least two isoforms that localize to the centrosome and the Golgi apparatus， and interact with numerous signaling proteins from multiple signal transduction pathways. These signaling proteins include type II protein kinase A， serine/threonine kinase protein kinase N， protein phosphatase 1， protein phosphatase 2a， protein kinase C-epsilon an。
