Protein

Serine/threonine-protein phosphatase SIT4

Gene

SIT4

Organism
Candida albicans (strain SC5314 / ATCC MYA-2876) (Yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Serine/threonine protein phosphatase which is involved in the dephosphorylation of the large subunit of RNA polymerase II. Is required in late G1 for normal G1 cyclin expression, bud initiation and expression of certain genes that are periodically expressed during late G1 (By similarity). Plays a role during hyphal growth through the regulation of cell wall biogenesis, osmosensing and protein translation. Involved in virulence in a mouse systemic infection model.By similarity2 Publications

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Binds 2 manganese ions per subunit.By similarity
