PLEKHA1（pleckstrin homology domain containing A1），癌症关联基因，基因ID：59338，该基因编码一个包含适配蛋白的pleckstrin同源结构域。编码的蛋白质定位在质膜上，在质膜上特异性结合磷脂酰肌醇3，4-二磷酸。这种蛋白可能参与了质膜信号复合物的形成。该基因多态性与年龄相关性黄斑变性有关。交替剪接导致多个转录变体。在5号染色体上发现了该基因的假基因。[由RefSeq提供，2010年9月]This gene encodes a pleckstrin homology domain-containing adapter protein. The encoded protein is localized to the plasma membrane where it specifically binds phosphatidylinositol 3，4-bisphosphate. This protein may be involved in the formation of signaling complexes in the plasma membrane. Polymorphisms in this gene are associated with age-related macular degeneration. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 5.[provided by RefSeq， Sep 2010]。
