Disease relevance of SH3KBP1

  • Herpes simplex virus 1 infected cell protein 0 forms a complex with CIN85 and Cbl and mediates the degradation of EGF receptor from cell surfaces [1].
  • Collectively, our data indicate that CIN85 might play an important role in HSV-1 infection [2].
 

High impact information on SH3KBP1

  • Cbl-CIN85-endophilin complex mediates ligand-induced downregulation of EGF receptors [3].
  • CIN85 was constitutively associated with endophilins, whereas CIN85 binding to the distal carboxy terminus of Cbl was increased on EGF stimulation [3].
  • Cbl, in turn, binds and ubiquitinates activated HGF receptor, and by recruiting the endophilin-CIN85 complex, it regulates receptor internalization [4].
  • Furthermore, by means of their Src-homology 3 domains, endophilins are able to bind CIN85, a recently identified protein that interacts with the Cbl proto-oncogene [4].
  • CIN85 and Cbl are involved in endocytosis and negative regulation of numerous receptor tyrosine kinases [1].
 

Biological context of SH3KBP1

 

Anatomical context of SH3KBP1

  • These results indicate a potential role of CIN85 in the B cell receptor-mediated signaling pathway [8].
  • Cbl rapidly recruits CIN85 (Cbl-interacting protein of 85K; ref. 6) and endophilins (regulatory components of clathrin-coated vesicles) to form a complex with activated EGF receptors, thus controlling receptor internalization [3].
  • Cbl-b and monoubiquitinated CIN85 are found in the complex with polyubiquitinated EGF receptors during prolonged EGF stimulation and are degraded together in the lysosome [9].
  • CIN85 mRNA is expressed ubiquitously in normal human tissues and cancer cell lines analyzed [10].
  • Here, we demonstrate that plaque formation by HSV-1 is reduced on HeLa cells expressing CIN85 ectopically [2].
 

Associations of SH3KBP1 with chemical compounds

  • Thus, our data demonstrate that Cbl/Cbl-b can mediate polyubiquitination of cargo as well as monoubiquitination of CIN85 to control endosomal sorting and degradation of receptor tyrosine kinases [9].
  • This motif was indispensable for CIN85 binding to Cbl/Cbl-b, to other CIN85 SH3 domains' effectors, and for mediating an intramolecular interaction between the SH3-A domain and the proline-rich region of CIN85 [11].
  • 2. Two of these DESTs, GIG10 and GIG18, are rapidly induced by dexamethasone within 2 h of treatment [12].
  • We found that CIN85 overexpression inhibits the FcepsilonRI-induced tyrosine phosphorylation of phospholipase Cgamma, thus altering calcium mobilization [13].
 

Physical interactions of SH3KBP1

  • Coimmunoprecipitation experiments using mammalian cells revealed that CIN85 directly bound to BLNK through its SH3 domains [8].
  • Interaction trap cloning was used to identify a CD2 cytoplasmic tail-binding protein termed CD2BP3 [14].
  • Further characterization of CIN85 binding to ASAP1 revealed that formation of the complex is independent on cell stimulation [15].
 

Regulatory relationships of SH3KBP1

  • Cbl-directed monoubiquitination of CIN85 is involved in regulation of ligand-induced degradation of EGF receptors [9].
  • Moreover, ternary complexes of CIN85 and Cbl are formed in vivo and are important for the ability of Cbl to promote epidermal growth factor receptor (EGFR) downregulation [16].
