Gene ID
59338
Species
Homo sapiens (Human)
Gene Name
pleckstrin homology domain containing, family A (phosphoinositide binding specific) member 1
Gene Symbol
PLEKHA1
Synonyms
TAPP1
Chromosome
10
Map Location
10q26.13
Summary
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]
