Uncharacterized protein YER034W; Protein of unknown function; non-essential gene; expression induced upon calcium shortage; protein abundance increases in response to DNA replication stress.

Cell wall biogenesis protein NCW2; Structural constituent of the cell wall; attached to the plasma membrane by a GPI-anchor; expression is upregulated in response to cell wall stress; null mutant is sensitive to the antifungal agent polyhexamethylene biguanide, resistant to zymolyase treatment and has increased chitin deposition.

Serine/threonine-protein kinase KDX1; Protein kinase; implicated in Slt2p mitogen-activated (MAP) kinase signaling pathway; interacts with numerous components in the mating pheromone and CWI MAPK pathways; associates with Rlm1p; KDX1 has a paralog, SLT2, that arose from the whole genome duplication.

Mitogen-activated protein kinase SLT2/MPK1; Serine/threonine MAP kinase; coordinates expression of all 19S regulatory particle assembly-chaperones (RACs) to control proteasome abundance; involved in regulating maintenance of cell wall integrity, cell cycle progression, nuclear mRNA retention in heat shock, septum assembly; required for mitophagy, pexophagy; affects recruitment of mitochondria to phagophore assembly site; plays role in adaptive response of cells to cold; regulated by the PKC1-mediated signaling pathway; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kin [...]

Protein SRL3; GTB motif (G1/S transcription factor binding) containing protein; binds SBF-regulated promoters in hydroxyurea-treated cells; when overexpressed, suppresses the lethality of a rad53 null mutation; potential Cdc28p substrate; SRL3 has a paralog, WHI5, that arose from the whole genome duplication.

Probable S-adenosylmethionine-dependent methyltransferase CRG1; S-AdoMet-dependent methyltransferase involved in lipid homeostasis; mediates resistance to a drug cantharidin; Belongs to the methyltransferase superfamily.

Uncharacterized membrane glycoprotein YNR065C; Protein of unknown function; protein-protein interactions suggest a possible role in actin patch formation; YNR065C is not an essential gene.

Inhibitory regulator protein BUD2/CLA2; GTPase activating factor for Rsr1p/Bud1p; plays a role in spindle position checkpoint distinct from its role in bud site selection; required for both axial and bipolar budding patterns; mutants exhibit random budding in all cell types; contains two PH-like domains.

Catalytic subunit of 1,3-beta-glucan synthase; involved in formation of the inner layer of the spore wall; activity positively regulated by Rho1p and negatively by Smk1p; GSC2 has a paralog, FKS1, that arose from the whole genome duplication; Belongs to the glycosyltransferase 48 family.
