ADDITIONAL INFORMATION for PMA1
SUMMARY PARAGRAPH for PMA1
PMA1 is an essential gene that encodes the major plasma membrane H+-ATPase in S. cerevisiae (4). By hydrolyzing ATP, Pma1p pumps H+ ions out of the cell, which creates an electrochemical proton gradient that regulates proper cytoplasmic pH and drives the secondary import of nutrients across the plasma membrane (reviewed in 7 and 8).
Pma1p is an abundant 100 kDa protein with 10 membrane-embedded domains (reviewed in 7 and 8). Its abundance, combined with its function as a prominent housekeeping gene, has led to its use as a marker for stress, secretion, and plasma membrane biogenesis (9 and reviewed in 10).
Pma1p is highly regulated by glucose, both transcriptionally and postranslationally (11). The presence of glucose induces a 2- to 4-fold increase in PMA1 expression, mediated by the transcription factors Rap1p and Gcr1p (12, 13). Glucose also triggers a rapid 5- to 10-fold increase in ATPase catalytic activity via Ptk2p-mediated phosphorylation of a serine residue in the Pma1p C-terminus (11, 14, 15). In contrast, phosphorylation of Pma1p by serine/threonine kinase (Yck1p and Yck2p), in the presence of glucose, is correlated with decreased proton pump activity (16). Glucose addition induces a Pma1p conformational change that is correlated with enzyme activity; moreover, glucose disrupts complexes between acetylated tubulin (Tub1p, Tub2p, and Tub3p) and Pma1p that are known to inhibit H+-ATPase activity (17 and references contained therein, 18). Finally, PMA1 transcription may be regulated by the cell cycle as its promoter is also a binding site for the transcription factor Mcm1p (19).
Pma1p homologs have been identified in A. thaliana and other fungi such as C. albicans and S. pombe (20, 21, 22). Additionally, H+-ATPase homologs in pathogenic fungi are being studied as targets for antifungal reagents (23 and reviewed in 24).
