RPSA, ribosomal protein SA, encoding a high-affinity non-integrin family, laminin receptor 1, which is also called 67-kDa laminin receptor, 37-kDa laminin receptor precursor (37LRP) and p40 ribosome-associated protein, has been associated with the invasive and metastatic behavior of cancer cells upon its overexpression. Here, RPSA is linked to cancer.
