SMI1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SMI1" - Protein involved in the regulation of cell wall synthesis in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

SMI1Protein involved in the regulation of cell wall synthesis; proposed to be involved in coordinating cell cycle progression with cell wall integrity; Protein involved in the regulation of cell wall assembly and 1,3-beta-glucan synthesis, possibly through the transcriptional regulation of cell wall glucan and chitin synthesis (505 aa)    
Predicted Functional Partners:
Catalytic subunit of 1,3-beta-D-glucan synthase, functionally redundant with alternate catalytic subunit Gsc2p; binds to regulatory subunit Rho1p; involved in cell wall synthesis and maintenance; localizes to sites of cell wall remodeling; Alternate catalytic subunit of the 1,3-beta-glucan synthase (GS). Synthesizes 1,3-beta-glucan, a major structural component of the yeast cell wall. Involved in cell wall synthesis, maintenance and cell wall remodeling (1876 aa)
Protein serine/threonine kinase essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC); Required for cell growth and for the G2->M transition of the cell division cycle. Mediates a protein kinase cascade; it activates BCK1 which itself activates MKK1/MKK2 (1151 aa)
Serine/threonine MAP kinase; involved in regulating maintenance of cell wall integrity, progression through the cell cycle, and nuclear mRNA retention in heat shock; required for mitophagy and pexophagy; affects recruitment of mitochondria to the ph /.../re assembly site (PAS); regulated by the PKC1-mediated signaling pathway; Serine/threonine protein kinase involved in a signal transduction pathway that plays a role in yeast cell morphogenesis and cell growth. This pathway seems to start by SMP3; then involve the kinase PKC1 that may act the BCK1 kinase that then phosphorylates MKK1 a [...] (484 aa)
Protein that induces appearance of [PIN+] prion when overproduced; predicted to be palmitoylated; Not known. Seems to be able to provoque the non- Mendelian trait [PIN(+)] which is required for the de novo appearance of the [PSI(+)] prion (282 aa)
Beta-1,3-glucanosyltransferase, required for cell wall assembly and also has a role in transcriptional silencing; localizes to the cell surface via a glycosylphosphatidylinositol (GPI) anchor; also found at the nuclear periphery; Splits internally a 1,3-beta-glucan molecule and transfers the newly generated reducing end (the donor) to the non- reducing end of another 1,3-beta-glucan molecule (the acceptor) forming a 1,3-beta linkage, resulting in the elongation of 1,3- beta-glucan chains in the cell wall. Involved in cell wall biosynthesis and morphogenesis (559 aa)
Protein rich in serine and threonine residues involved in protein kinase C signaling pathway, which controls cell integrity; overproduction suppresses pkc1 mutations; Dosage dependent suppressor of PKC1 deletion and MPK1 deletion. Involved in cell lysis (851 aa)
Guanine nucleotide exchange factor (GEF) for ADP ribosylation factors involved in proliferation of the Golgi, intra-Golgi transport and ER-to-Golgi transport; found in the cytoplasm and on Golgi-associated coated vesicles; May play a role in vesicular budding and traffic between compartments of the Golgi apparatus (2009 aa)
MADS-box transcription factor, component of the protein kinase C-mediated MAP kinase pathway involved in the maintenance of cell integrity; phosphorylated and activated by the MAP-kinase Slt2p; May function as a transcription factor downstream of MPK1 that is subject to activation by the MPK1 mitogen-activated protein kinase pathway. Binds to the DNA sequence 5’- CTA[TA](4)TAG-3’. At least some RML1 target genes are involved in cell wall biosynthesis (676 aa)
Putative sensor/transporter protein involved in cell wall biogenesis; contains 14-16 transmembrane segments and several putative glycosylation and phosphorylation sites; null mutation is synthetically lethal with pkc1 deletion; Involved in the maintenance of cell wall integrity. Required for the replacement of the diacylglycerol moiety by ceramides during GPI-anchor maturation (953 aa)
Type II integral membrane protein required for beta-1,6 glucan biosynthesis; putative beta-glucan synthase; localizes to the ER, plasma membrane, sites of polarized growth and secretory vesicles; functionally redundant with Skn1p; Involved in the synthesis of (1->6)- and (1->3)-beta-D- glucan polymers of the yeast cell wall in vivo. It is required for full activity of beta-glucan synthase in vitro. May be involved in the maturation and transport of cell wall proteins (CWP) to the cell wall. May act as a transglucosidase and contribute to the construction of a protein-bound glucan-struc [...] (720 aa)
