STRINGSTRING
RAX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"RAX1" - Protein involved in bud site selection during bipolar budding 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

RAX1Protein involved in bud site selection during bipolar budding; localization requires Rax2p; has similarity to members of the insulin-related peptide superfamily; Required for the establishment of the bipolar budding pattern. Involved in selecting bud sites at both the distal and proximal poles of daughter cells as well as near previously used division sites on mother cells. Has a role in the localization of BUD8, the distal bipolar budding landmark, and of BUD9, the proximal pole landmark (435 aa)    
Predicted Functional Partners:
RAX2
N-glycosylated protein involved in the maintenance of bud site selection during bipolar budding; localization requires Rax1p; RAX2 mRNA stability is regulated by Mpt5p; Required for the maintenance of the bipolar budding pattern. Involved in selecting bud sites at both the distal and proximal poles of daughter cells as well as near previously used division sites on mother cells (1220 aa)

BUD8
Protein involved in bud-site selection; diploid mutants display a unipolar budding pattern instead of the wild-type bipolar pattern, and bud at the proximal pole; May be involved in positioning the distal bud pole signal (603 aa)
       
 
  0.880
BUD9
Protein involved in bud-site selection; mutant has increased aneuploidy tolerance; diploid mutants display a unipolar budding pattern instead of the wild-type bipolar pattern, and bud at the distal pole; May be involved in positioning the proximal bud pole signal (547 aa)

AXL1
Haploid specific endoprotease that performs one of two N-terminal cleavages during maturation of a-factor mating pheromone; required for axial budding pattern of haploid cells; Probable protease. Involved in axial budding (1208 aa)
     
 
  0.770
AXL2
Integral plasma membrane protein required for axial budding in haploid cells, localizes to the incipient bud site and bud neck; glycosylated by Pmt4p; potential Cdc28p substrate; Required for haploid cells axial budding pattern. Acts as an anchor to help direct new growth components and/or polarity establishment components like the BUD5 GTP/GDP exchange factor to localize at the cortical axial budding site. Regulates septin organization in late G1 independently of its role in polarity-axis determination (823 aa)

SEI1
Seipin protein involved in lipid droplet morphology, number, and size; proposed to be involved in lipid metabolism; related to the human BSCL2 which is associated with lipodystrophy; Involved in lipid metabolism and lipid droplet (LD) morphology, number, and size (PubMed-18093937, PubMed-18250201). Facilitates initiation of LD formation, and ensures that vectorial budding of LDs from the ER is directed towards the cytoplasm (PubMed-25540432) (285 aa)

GPA1
GTP-binding alpha subunit of the heterotrimeric G protein that couples to pheromone receptors; negatively regulates the mating pathway by sequestering G(beta)gamma and by triggering an adaptive response; activates Vps34p at the endosome; Alpha subunit of the heterotrimeric guanine nucleotide- binding protein (G protein) that mediates mating pheromone signal transduction. Binding of alpha-factor or a-factor to its cognate transmembrane receptor STE2 and STE3, respectively, allows the receptor to serve as a guanine nucleotide exchange factor (GEF) on GPA1. The exchange of GDP for GTP on [...] (472 aa)

BUD4
Involved in bud-site selection and required for the axial budding pattern; localizes with septins to bud neck in mitosis and may constitute an axial landmark for next round of budding; required for the formation of a double septin ring, and generall /.../the organization of septin structures; potential Cdc28p substrate; Required for establishment of the axial budding pattern in haploid cells. Cooperates with other bud site selection proteins to recognize a spatial landmark during mitosis and they subsequently become a landmark for downstream polarity establishment factors that coordina [...] (1447 aa)
           
  0.641
BUD3
Protein involved in bud-site selection and required for axial budding pattern; localizes with septins to bud neck in mitosis and may constitute an axial landmark for next round of budding; Co-assembles with BUD4 at bud sites. BUD4 and BUD3 may cooperate to recognize a spatial landmark (the neck filaments) during mitosis and they subsequently become a landmark for establishing the axial budding pattern in G1 (1636 aa)

BUD5
GTP/GDP exchange factor for Rsr1p (Bud1p) required for both axial and bipolar budding patterns; mutants exhibit random budding in all cell types; GDP-GTP exchange factor (GEF) for the small GTPase BUD1/RSR1. Regulates the activity of BUD1 together with BUD2 which is a GTPase-activating protein (GAP) of BUD1. Required to produce both the axial and bipolar patterns of bud site selection. Determines the orientation of division axis. Overexpression can suppress mutations in PRP20 which is the GEF for GSP1. May be a cytoplasmic GEF for GSP1. Might also act on the Ras-like protein CDC42.
