Unlike somatic ubiquitous hyaluronidases that are active only at acidic pH [ 8 ] , SPAM1 has hyaluronidase activity at both neutral and acidic pHs, which arise from two different regions within the hyaluronidase domain [ 4 ] . The neutral enzyme activity, which is predominant in insoluble membrane-bound SPAM1, is necessary for sperm to penetrate the hyaluronic acid (HA)-rich extracellular matrix of the cumulus cells surrounding the oocyte.
These mice also develop autoimmunity against thyroid and gastric parietal cells [ 22 ] . It is well established that these mice with ovarian autoimmunity also develop circulating autoantibodies against the oocyte cytoplasm, the zona pellucida, and against steroid producing cells [ 22 ] . While we found evidence that one half of our patients had specific antibodies directed against the zona pellucida, we did not find any consistent pattern of immunofluorescence to suggest that our patients had antibodies directed against the oocyte cytoplasm or the steroid producing cells of the ovary.
The reason for this apparent discrepancy is unclear but may be related to a "spare receptor" phenomenon in the oocyte expression system.
Besides inhibiting proteasome activity, the peptide aldehyde proteasome inhibitors have been also reported to repress certain lysosomal cysteine proteases and calpains [ 49 ] . The finding that MG-132 can obstruct the casein degrading activity of the calcium-dependent protease calpain [ 50 ] appears relevant to oocyte maturation.
