Protein attributes

Sequence length	236 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Negatively regulates the high-osmolarity glycerol (HOG) pathway through its negative regulation of the HOG1 kinase activity. Mediates the binding between the PTC1 phosphatase and the PBS2 MAP/ERK kinase (MEK). With PTC1, regulates endoplasmic reticulum inheritance through the cell wall integrity (CWI) MAPK pathway by modulating the MAPK, SLT2. Ref.4 Ref.6 Ref.7
Subunit structure	Interacts with PBS2 and PTC1. Ref.6
Subcellular location	Cytoplasm.
Miscellaneous	Present with 521 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Contains 1 SH3 domain.
