Synonym CT22, SP17, SP17-1, Sperm surface protein Sp17, Cancer/testis antigen 22, Sperm autoantigenic protein 17, Sperm protein 17, SPA17.
Background SPA17 is a protein present at the cell surface. SPA17 was characterized by its participation in the binding of sperm to the zona pellucida of the oocyte. The central portion of SPA17 has carbohydrate binding motifs and likely takes part in cell-cell adhesion functions such as immune cell migration and metastasis.
Description SPA17 Human Recombinant expressed in E. coli is a single polypeptide chain containing 174a.a. (1-151) and having a molecular weight of 19.8kDa. SPA17 is fused to a 23a.a. His-tag at N-terminus and purified by unique purification methods.
