Description of YGR014W: Mucin family member involved in the Cdc42p- and MAP kinase-dependent filamentous growth signaling pathway; also functions as an osmosensor in parallel to the Sho1p-mediated pathway; potential Cdc28p substrate[1][2][3][4]

Transmembrane Domain GxxxG

The transmembrane domain of Msb2 shows homology with the SKG6/AXL2 alpha-helix transmembrane domain (IPR014805). In particular, this domain begins with iiGlviGvvvG. The presence of multiple, overlapping GxxxG motifs [5] strongly indicates that Msb2 dimerises.


Protein Details

Protein Modification

Modification(s): Phosphorylation

Identified as an efficient substrate of Clb2-Cdk1-as1 in a screen of a proteomic GST-fusion library. [4] [6]
