NCIt definition : Human SPAM1 wild-type allele is located in the vicinity of 7q31.3 and is approximately
46 kb in length. This allele, which encodes hyaluronidase PH-20 protein, plays a role
in hyaluronic acid induced cell signal transduction, and sperm-zona pellucida adhesion.;
NCIt note : Abnormal expression of this gene in tumors has implicated this protein in degradation
of basement membranes leading to tumor invasion and metastasis.;
