The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Spasmolytic Protein, domain 1
".
FunFam 4: zona pellucida sperm-binding protein 4 isoform X1
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 3 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the

|
Binding of sperm to zona pellucida GO:0007339
The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

Binding of sperm to zona pellucida GO:0007339
The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

|
Acrosomal vesicle exocytosis GO:0060478
The calcium ion regulated exocytosis which results in fusion of the acrosomal vesicle with the plasma membrane of the sperm as part of the acrosome reaction.
|
1 | Q12836 (/IMP) |
|
Positive regulation of acrosome reaction GO:2000344

Extracellular region GO:0005576
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

|
Protein-containing complex GO:0032991
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
