Description

40S ribosomal protein SA is a Ribosomal protein that in humans is encoded by the RPSA gene. This RPSA gene encodes a high-affinity, non-integrin family, laminin receptor 1. This receptor has been variously called 67 kD laminin receptor, 37 kD laminin receptor precursor (37LRP) and p40 ribosome-associated protein. The amino acid sequence of laminin receptor 1 is highly conserved through evolution, suggesting a key biological function. It has been observed that the level of the laminin receptor transcript is higher in colon carcinoma tissue and lung cancer cell line than their normal counterparts. Also, there is a correlation between the upregulation of this polypeptide in cancer cells and their invasive and metastatic phenotype. Multiple copies of this gene exist, however, most of them are pseudogenes thought to have arisen from retropositional events. Two alternatively spliced transcript variants encoding the same protein have been found for this gene.

Application Notes

Differences in protocols and secondary/substrate sensitivity may require the RPSA antibody to be titrated for optimal performance.

Immunogen

Amino acids S2-S138 from the human protein were used as the immunogen for the RPSA antibody.

Storage

After reconstitution, the RPSA antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
