Stretch-activated cation channel MID1

Gene

MID1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Calcium-permeable, cation-selective stretch-activated channel (SAC). Required for calcium influx and for vitality of MATa cells in a late, pheromone-induced event of the mating process requiring calcium induced signaling. Functions together with CCH1 to ensure that adequate levels of Ca2+ are supplied to PMR1 to sustain secretion and growth. Required for growth in low-calcium environments. Together with CCH1, essential for tolerance to iron stress, which leads to an increased oxidative poise, and to cold stress.4 Publications
