Secondary Accession Numbers Not Available
Name Hyaluronidase PH-20
Description Not Available
Synonyms
  1. SubName: Sperm adhesion molecule 1 (PH-20 hyaluronidase, zona pellucida binding), isoform CRA_c
  2. Hyal-PH20
  3. Hyaluronoglucosaminidase PH-20
  4. Sperm adhesion molecule 1
  5. Sperm surface protein PH-20
Gene Name SPAM1
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific Function Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.
