"LYST" - lysosomal trafficking regulator in Homo sapiens
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 Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
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
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others
textmining edge
textmining
coexpression edge
co-expression
homology edge
protein homology

LYSTlysosomal trafficking regulator; May be required for sorting endosomal resident proteins into late multivesicular endosomes by a mechanism involving microtubules (3801 aa)    
Predicted Functional Partners:
VTA1
Vps20-associated 1 homolog (S. cerevisiae); Involved in the endosomal multivesicular bodies (MVB) pathway. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. Thought to be a cofactor of VPS4A/B, which catalyzes disassembles membrane-associated ESCRT-III assemblies. Involved in the sorting and down-regulation of EGFR (By similarity). Involved in HIV-1 budding (307 aa)

LTA4H
leukotriene A4 hydrolase; Epoxide hydrolase that catalyzes the final step in the biosynthesis of the proinflammatory mediator leukotriene B4. Has also aminopeptidase activity (611 aa)
            score_image   0.750
NID1
nidogen 1; Sulfated glycoprotein widely distributed in basement membranes and tightly associated with laminin. Also binds to collagen IV and perlecan. It probably has a role in cell- extracellular matrix interactions (1247 aa)
            score_image   0.749
PIK3R4
phosphoinositide-3-kinase, regulatory subunit 4; Regulatory subunit of the PI3K complex. May regulate membrane trafficking late in the endocytic pathway (1358 aa)
      score_image     score_image   0.687
UNC13D
unc-13 homolog D (C. elegans); Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse. Regulates assembly of recycling and late endosomal structures, leading to the formation of an endosomal exocytic compartment that fuses with perforin-containing granules at the immunologic synapse and licences them for exocytosis. Regulates Ca(2+)-dependent secretory lysosome exocytosis in mast cells (1090 aa)
            score_image   0.658
STX11
syntaxin 11; SNARE that acts to regulate protein transport between late endosomes and the trans-Golgi network (287 aa)
            score_image   0.645
RAB27A
RAB27A, member RAS oncogene family; Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse (221 aa)
            score_image   0.639
STXBP2
syntaxin binding protein 2; Involved in intracellular vesicle trafficking and vesicle fusion with membranes. Contributes to the granule exocytosis machinery through interaction with soluble N- ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins that regulate membrane fusion. Regulates cytotoxic granule exocytosis in natural killer (NK) cells (593 aa)
            score_image   0.596
HGS
hepatocyte growth factor-regulated tyrosine kinase substrate; Involved in intracellular signal transduction mediated by cytokines and growth factors. When associated with STAM, it suppresses DNA signaling upon stimulation by IL-2 and GM-CSF. Could be a direct effector of PI3-kinase in vesicular pathway via early endosomes and may regulate trafficking to early and late endosomes by recruiting clathrin. May concentrate ubiquitinated receptors within clathrin-coated regions. Involved in down- regulation of receptor tyrosine kinase via multivesicular body (MVBs) when complexed with STAM (E [...] (777 aa)

VPS4B
vacuolar protein sorting 4 homolog B (S. cerevisiae); Involved in late steps of the endosomal multivesicular bodies (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, possibly in combination with membrane fission. Redistributes the ESCRT-III components to the cytoplasm for further rounds of MVB sorting. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growt [...] (444 aa)
