Gene Ontology Help

a-agglutinin Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Cell surface mannoproteins that mediate cell-cell adhesion of haploid cells during mating. The a- and alpha-agglutinins, expressed by MATa and MATalpha cells, respectively, interact directly with 1:1 stoichiometry. Exposure to the pheromone expressed by the opposite mating type induces agglutinin expression and thus facilitates the agglutination reaction.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
