背景 | Sperm adhesion molecule 1 (SPAM1), also known as PH-20 hyaluronidase (1), is encoded by one of the six hyaluronidase-like genes (1, 2, 3). SPAM1 is a GPI‑anchored enzyme located on the sperm surface and inner acrosomal membrane (4). SPAM1 degrades hyaluronic acid (HA), a major structural glycosaminoglycan found in extracellular matrices and basement membranes. The enzyme activity enables sperm to penetrate through the HA-rich cumulus cell layer surrounding the oocyte and therefore facilitates the fertilization process (5). However, detailed enzymatic analysis of this enzyme is hindered by the limited techniques/methods available to monitor the HA degradation products (6). A novel method for analyzing SPAM1 activity was utilized here. Because of the structural similarity between HA (repeating units of GlcA beta 1-3GlcNAc) and chondroitin sulfate (repeating units of GlcA beta 1-3GalNAc), the enzyme is also able to hydrolyze chondroitin sulfate. In this assay, radiolabeled chondroitin sulfate was digested with recombinant SPAM1. Degradation products were then separated using a polyacrylamide electrophoresis and visualized with an X-ray film (7). The bovine SPAM1 is 63% identical to human homologue in sequence. |

Detection of Bovine SPAM1 by Western Blot. Western blot shows lysates of recombinant bovine SPAM1 (Catalog # 6436-GH). PVDF membrane was probed with 1 µg/mL of Sheep Anti-Bovine SPAM1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6436) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for SPAM1 at approximately 78 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8. |
