STRINGSTRING
LDB18 protein (Saccharomyces cerevisiae) - STRING interaction network
"LDB18" - Component of the dynactin complex, which is required for dynein activity 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

LDB18Component of the dynactin complex, which is required for dynein activity; null mutant exhibits defects in nuclear migration and spindle orientation and has reduced affinity for alcian blue dye; has homology to mammalian dynactin subunit p24; May be involved in protein-linked oligosaccharide phosphorylation since the deletion reduces the negative charge of the cell surface (179 aa)    
Predicted Functional Partners:
JNM1
Component of the yeast dynactin complex, consisting of Nip100p, Jnm1p, and Arp1p; required for proper nuclear migration and spindle partitioning during mitotic anaphase B; Component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint. JNM1 is associated with the rod and links it to the projecting sidearm. Required for proper nuclear migration during the mitotic cell [...] (373 aa)

NIP100
Large subunit of the dynactin complex, which is involved in partitioning the mitotic spindle between mother and daughter cells; putative ortholog of mammalian p150(glued); Motor-binding component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint (868 aa)
       
  0.988
ARP1
Actin-related protein of the dynactin complex; required for spindle orientation and nuclear migration; putative ortholog of mammalian centractin; Core component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint. ARP1 forms the backbone filament of the dynactin rod structure and serves as the scaffold for the remaining subunits. Required for proper orientation of t [...] (384 aa)
       
  0.945
ARP10
Component of the dynactin complex, localized to the pointed end of the Arp1p filament; may regulate membrane association of the complex; Pointed-end-associated component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint. May regulate the association of the dynactin complex with the plasma membrane (284 aa)
       
  0.871
KXD1
Subunit of the BLOC-1 complex involved in endosomal maturation; null mutant is sensitive to drug inducing secretion of vacuolar cargo; GFP-fusion protein localizes to the endosome; Component of the biogenesis of lysosome-related organelles complex-1 (BLOC-1) involved in endosomal cargo sorting (218 aa)
           
  0.697
YNR068C
Putative protein of unknown function (272 aa)
       
      0.682
DYN1
Cytoplasmic heavy chain dynein, microtubule motor protein, required for anaphase spindle elongation; involved in spindle assembly, chromosome movement, and spindle orientation during cell division, targeted to microtubule tips by Pac1p; Cytoplasmic dynein acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. Required to maintain uniform nuclear distribution in hyphae. May play an important role in the proper orientation of the mitotic sp [...] (4092 aa)
       
 
  0.679
DYN3
Dynein light intermediate chain (LIC); localizes with dynein, null mutant is defective in nuclear migration; Component of the cytoplasmic dynein which acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. May play an important role in the proper orientation of the mitotic spindle into the budding daughter cell yeast. Probably required for normal progression of the cell cycle (312 aa)
           
  0.626
PAC11
Dynein intermediate chain, acts in the cytoplasmic dynein pathway, forms cortical cytoplasmic microtubule capture site with Num1p; null mutant is defective in nuclear migration, essential in the absence of CIN8; Required for viability in the absence of the kinesin- related CIN8 mitotic motor. May be a dynein intermediate chain (533 aa)
       
 
  0.615
NUM1
Protein required for nuclear migration, localizes to the mother cell cortex and the bud tip; may mediate interactions of dynein and cytoplasmic microtubules with the cell cortex; Controls nuclear migration. NUM1 specifically controls the interaction of the bud neck cytoskeleton with the pre- divisional G2 nucleus. Functions in dynein-anchoring. During late anaphase forms dynein-interacting cortical microtubule capture sites at both cellular poles. This leads to dynein-dependent sliding of the microtubules in the bud (2748 aa)
