STRINGSTRING
MSB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MSB1" - Protein involved in positive regulation of both 1,3-beta-glucan synthesis and the Pkc1p-MAPK pathway, potential Cdc28p substrate in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

MSB1Protein involved in positive regulation of both 1,3-beta-glucan synthesis and the Pkc1p-MAPK pathway, potential Cdc28p substrate; multicopy suppressor of temperature-sensitive mutations in CDC24 and CDC42, and of mutations in BEM4; May play a role in polarity establishment and bud formation. The MSB1 gene may be functionally redundant (1137 aa)    
Predicted Functional Partners:
CDC42
Small rho-like GTPase, essential for establishment and maintenance of cell polarity; mutants have defects in the organization of actin and septins; Involved in development of cell polarity during the cell division cycle, and essential for bud emergence. Affects signaling in the pheromone-response pathway through the STE20 protein kinase. Negatively regulated by the GTPase-activating proteins RGA1, BEM3, and BEM4 (191 aa)
       
 
  0.937
BEM2
Rho GTPase activating protein (RhoGAP) involved in the control of cytoskeleton organization and cellular morphogenesis; required for bud emergence; GTPase-activating protein (GAP) for RHO1 and RHO2. Involved in the control of cellular morphogenesis. Required for proper bud site selection and bud emergence (2167 aa)
       
 
  0.937
BEM1
Protein containing SH3-domains, involved in establishing cell polarity and morphogenesis; functions as a scaffold protein for complexes that include Cdc24p, Ste5p, Ste20p, and Rsr1p; Necessary for cell polarization during vegetative growth. May link the cytoskeleton to morphogenic determinants on the cell surface (551 aa)
       
 
  0.937
CDC24
Guanine nucleotide exchange factor (GEF or GDP-release factor) for Cdc42p; required for polarity establishment and maintenance, and mutants have morphological defects in bud formation and shmooing; Promotes the exchange of CDC42-bound GDP by GTP. Controls the polarity of calmodulin, and the calcium regulatory process of bud emergence. CDC24 may be involved in the initial selection and organization of the budding site (854 aa)
       
 
  0.937
BOI1
Protein implicated in polar growth, functionally redundant with Boi2p; interacts with bud-emergence protein Bem1p; contains an SH3 (src homology 3) domain and a PH (pleckstrin homology) domain; Binds to the BEM1 protein (980 aa)
       
 
  0.874
RHO1
GTP-binding protein of the rho subfamily of Ras-like proteins, involved in establishment of cell polarity; regulates protein kinase C (Pkc1p) and the cell wall synthesizing enzyme 1,3-beta-glucan synthase (Fks1p and Gsc2p); Acts as a central regulator in the cell wall integrity signaling pathway, which is regulated by the cell cycle and in response to various types of cell wall stress. Integrates signals from different cell surface sensors, and activates a set of effectors, regulating processes including beta-glucan synthesis at the site of wall remodeling, gene expression related to c [...] (209 aa)
       
 
  0.870
BOI2
Protein implicated in polar growth, functionally redundant with Boi1p; interacts with bud-emergence protein Bem1p; contains an SH3 (src homology 3) domain and a PH (pleckstrin homology) domain; Binds to the BEM1 protein. Involved in bud formation (1040 aa)
     
 
  0.777
RIM8
Protein involved in proteolytic activation of Rim101p in response to alkaline pH; interacts with ESCRT-1 subunits Stp22p and Vps28p; essential for anaerobic growth; member of the arrestin-related trafficking adaptor family; Required for the proteolytic cleavage of the transcriptional repressor RIM101 in response to alkaline ambient pH, which is necessary for sporulation and invasive growth (542 aa)
       
      0.699
YPL216W
Putative protein of unknown function; YPL216W is not an essential gene; May be required for the activity of an ISWI chromatin- remodeling complex (1102 aa)
       
      0.682
HHF2
Histone H4, core histone protein required for chromatin assembly and chromosome function; one of two identical histone proteins (see also HHF1); contributes to telomeric silencing; N-terminal domain involved in maintaining genomic integrity; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-trans [...] (103 aa)
