Target data
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.

Supplementary info

- Activity summary
SPAM1 also known as sperm adhesion molecule 1 or PH-20 refers to a glycoprotein found on the sperm cell surface. Its molecular mass is approximately 64 kDa. This protein is primarily expressed in the testes and epididymis where it plays a role in sperm maturation. SPAM1 possesses hyaluronidase activity breaking down hyaluronic acid present in the cumulus cell matrix of the female reproductive tract during fertilization. It aids sperm in penetrating the egg's outer layers which is important for successful fertilization.
- Biological function summary
SPAM1 participates in sperm penetration through the zona pellucida an essential step in fertilization. It acts independently facilitating sperm passage by degrading surrounding extracellular matrices. SPAM1 while not part of a larger protein complex interacts directly with the female reproductive tract's biochemical structures. These interactions ensure an efficient sperm-vs-egg recognition process that aids in sperm-egg fusion. Its enzymatic activity is central to this sperm-egg binding and membrane fusion.
- Pathways
SPAM1 contributes significantly to the fertilization pathway specifically the Acrosome Reaction. It interacts indirectly with proteins like ZP3 a zona pellucida protein that triggers the acrosome reaction necessary for sperm to penetrate the ovum. Additionally SPAM1 plays a minor role in the hyaluronan-mediated motility pathway interacting faintly with the extracellular matrix components to enhance sperm motility and penetration.
- Associated diseases and disorders
SPAM1 has been implicated in certain infertility cases particularly those involving the failure of sperm to penetrate the egg successfully. This condition might relate to defects or alterations in SPAM1 activity or expression. Moreover some studies suggest a possible link between SPAM1 and testicular cancer where aberrant expression could influence tumorigenesis. SPAM1 anomalies may associate with other proteins like EZH2 involved in various cancers suggesting broader functional implications beyond reproductive biology.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SPAM1 antibody [EPR22906-57] - BSA and Azide free (ab256482)
Immunohistochemical analysis of paraffin-embedded human testis tissue labeling SPAM1 with Anti-SPAM1 antibody [EPR22906-57] ab231771 at 1/250 dilution (2.11μg/ml) followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (Rabbit specific IHC polymer detection kit HRP/DAB ab209101). Positive staining on human testis (PMID/ 12932297) is observed. The section was incubated with Anti-SPAM1 antibody [EPR22906-57] ab231771 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20mins. Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (Rabbit specific IHC polymer detection kit HRP/DAB ab209101).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-SPAM1 antibody [EPR22906-57] ab231771).
