STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

FAM221BProtein FAM221B; Family with sequence similarity 221 member B. (402 aa)    
Predicted Functional Partners:
ATG13
Autophagy-related protein 13; Autophagy factor required for autophagosome formation and mitophagy. Target of the TOR kinase signaling pathway that regulates autophagy through the control of the phosphorylation status of ATG13 and ULK1, and the regulation of the ATG13-ULK1-RB1CC1 complex. Through its regulation of ULK1 activity, plays a role in the regulation of the kinase activity of mTORC1 and cell proliferation.
    
   0.680
ATG101
Autophagy-related protein 101; Autophagy factor required for autophagosome formation. Stabilizes ATG13, protecting it from proteasomal degradation. Belongs to the ATG101 family.
    
 
 0.669
TMEM202
Transmembrane protein 202.
      
 0.646
ULK1
Serine/threonine-protein kinase ULK1; Serine/threonine-protein kinase involved in autophagy in response to starvation. Acts upstream of phosphatidylinositol 3-kinase PIK3C3 to regulate the formation of autophagophores, the precursors of autophagosomes. Part of regulatory feedback loops in autophagy: acts both as a downstream effector and negative regulator of mammalian target of rapamycin complex 1 (mTORC1) via interaction with RPTOR. Activated via phosphorylation by AMPK and also acts as a regulator of AMPK by mediating phosphorylation of AMPK subunits PRKAA1, PRKAB2 and PRKAG1, leadi [...]
    
 
 0.608
RB1CC1
RB1-inducible coiled-coil protein 1; Involved in autophagy. Regulates early events but also late events of autophagosome formation through direct interaction with Atg16L1. Required for the formation of the autophagosome-like double-membrane structure that surrounds the Salmonella-containing vacuole (SCV) during S.typhimurium infection and subsequent xenophagy (By similarity). Involved in repair of DNA damage caused by ionizing radiation, which subsequently improves cell survival by decreasing apoptosis (By similarity). Inhibits PTK2/FAK1 and PTK2B/PYK2 kinase activity, affecting their [...]

C7orf57
Uncharacterized protein C7orf57; Chromosome 7 open reading frame 57.
      
 0.527
FNDC8
Fibronectin type III domain containing 8.
   
  
 0.503
CABCOCO1
Ciliary-associated calcium-binding coiled-coil protein 1; Calcium-binding protein. May be involved in the control of sperm flagellar movement.
   
  
 0.477
SPAG8
Sperm-associated antigen 8; Plays a role in spermatogenesis by enhancing the binding of CREM isoform tau to its coactivator FHL5 and increasing the FHL5- regulated transcriptional activation of CREM isoform tau (By similarity). Involved in the acrosome reaction and in binding of sperm to the zona pellucida (By similarity). Plays a role in regulation of the cell cycle by controlling progression through the G2/M phase, possibly by delaying the activation of CDK1 which is required for entry into mitosis. May play a role in fertility and microtubule formation through interaction with RANBP9.

SPAAR
Small regulatory polypeptide of amino acid response; [Isoform 2]: Negative regulator of amino acid sensing and mTORC1, a signaling complex promoting cell growth in response to growth factors, energy levels and amino acids. Negatively regulates mTORC1 activation by inhibiting recruitment of mTORC1 to lysosomes upon stimulation with amino acids: acts by promoting the formation of a tightly bound supercomplex composed of the lysosomal V- ATPase, Ragulator and Rag GTPases, preventing recruitment of mTORC1. Acts as a regulator of muscle regeneration following injury by regulating mTORC1 act [...]
