Systematic name YDR085C
Gene name AFR1
Feature type ORF, Verified
Coordinates Chr IV:616150..614288
Primary SGDID S000002492

Description of YDR085C: Protein required for pheromone-induced projection (shmoo) formation; regulates septin architecture during mating; has an RVXF motif that mediates targeting of Glc7p to mating projections; interacts with Cdc12p; AFR1 has a paralog, YER158C, that arose from the whole genome duplication[1][2][3][4][5][6]
