| Type: | Domain | Name: | Pheromone alpha factor receptor, double transmembrane domain |
| Description: | Pheromone alpha factor receptor (STE2) is the receptor for the peptide pheromone alpha factor, which is a mating factor of yeast []. Saccharomyces cerevisiae haploid cells secrete and respond to peptide mating factors; alpha cells secrete alpha factor, which induces cell-cycle arrest and expression of various genes in a cells, while a cells produce a factor, which has similar actions on alpha cells.This entry represents a double transmembrane domain towards the N terminus of the alpha factor receptor. The ligand-binding site is probably in this domain []. | Short Name: | STE2_TM1-TM2 |
