Leupaxin is a protein that in humans is encoded by the LPXN gene.[5][6]

The product encoded by this gene is preferentially expressed in hematopoietic cells and is most homologous to the focal adhesion protein, paxillin. It may function in cell type-specific signaling by associating with PYK2, a member of focal adhesion kinase family. As a substrate for a tyrosine kinase in lymphoid cells, this protein may also function in, and be regulated by tyrosine kinase activity.[6]
