ID:ADAM2_HUMAN DESCRIPTION: RecName: Full=Disintegrin and metalloproteinase domain-containing protein 2; Short=ADAM 2; AltName: Full=Cancer/testis antigen 15; Short=CT15; AltName: Full=Fertilin subunit beta; AltName: Full=PH-30; Short=PH30; AltName: Full=PH30-beta; Flags: Precursor; FUNCTION: Sperm surface membrane protein that may be involved in sperm-egg plasma membrane adhesion and fusion during fertilization. Could have a direct role in sperm-zona binding or migration of sperm from the uterus into the oviduct. Interactions with egg membrane could be mediated via binding between its disintegrin-like domain to one or more integrins receptors on the egg. This is a non catalytic metalloprotease-like protein. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: Expressed specifically in spermatogenic cells in the seminiferous cells. Not detected in fetal tissues. DOMAIN: A tripeptide motif (FEE) within disintegrin-like domain could be involved in the binding to egg integrin receptor and thus could mediate sperm/egg binding. PTM: The prodomain and the metalloprotease domain are cleaved during the epididymal maturation of the spermatozoa. MISCELLANEOUS: In mammals, exists as a heterodimer composed of an alpha and beta subunits. In human, fertilin subunit alpha is a pseudogene. SIMILARITY: Contains 1 disintegrin domain. SIMILARITY: Contains 1 EGF-like domain. SIMILARITY: Contains 1 peptidase M12B domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
