PLEKHA1 Antibody / TAPP-1

Pleckstrin homology domain-containing family A member 1, also called Tandem PH domain-containing protein 1 (TAPP-1), is a protein that in humans is encoded by the PLEKHA1 gene. 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.
