Therefore, sperm capacitation can only be applied to Aves to refer to gene products involved in processes that occur prior to sperm being deposited from the avian male. The term cannot apply to processes occurring in the avian female reproductive tract.</rdfs:comment> <skos:notation>GO:0048240</skos:notation> <obo_purl:IAO_0000115>A process required for sperm to reach fertilization competence. Sperm undergo an incompletely understood series of morphological and molecular maturational processes, termed capacitation, involving, among other processes, protein tyrosine phosphorylation and increased intracellular calcium.</obo_purl:IAO_0000115> <oboinowl_gen:hasOBONamespace>biological_process</oboinowl_gen:hasOBONamespace> <oboinowl_gen:id>GO:0048240</oboinowl_gen:id> <metadata_def:prefLabel>sperm capacitation</metadata_def:prefLabel> <oboinowl_gen:hasRelatedSynonym>sperm activation</oboinowl_gen:hasRelatedSynonym> <metadata_def:mappingLoom>spermcapacitation</metadata_def:mappingLoom> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> <metadata:treeView rdf:resource="http://purl.obolibrary.org/obo/GO_0007286"/> <metadata:obo/part_of rdf:resource="http://purl.obolibrary.org/obo/GO_0007286"/> </owl:Class> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_0060474"> <metadata:obo/part_of> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_0048240"> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> </rdf:Description> </metadata:obo/part_of> <metadata:treeView rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_1902490"> <obo_purl:RO_0002211 rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_1902491"> <obo_purl:RO_0002212 rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/GO_1902492"> <obo_purl:RO_0002213 rdf:resource="http://purl.obolibrary.org/obo/GO_0048240"/> </rdf:Description> </rdf:RDF>
