81cd03744421421.144[                     -                           ]SOCS_SSB1SOCS (suppressors of cytokine signaling) box of SSB1 (SPRY domain-containing SOCS box proteins)-like proteins. SSB proteins contain a central SPRY domain and a C-terminal SOCS. SSB1 has been shown to bind to MET, the receptor protein-tyrosine kinase for hepatocyte growth factor (HGF), both the absence and the presence of HGF and enhances the HGF-MET-induced mitogen-activated protein kinases Erk-transcription factor Elk-1-serum response elements (SRE) pathway. SSB1, like SSB2 and SSB4, also interacts with prostate apoptosis response protein-4. Both types of interactions are mediated through the SPRY domain. The general function of the SOCS box is the recruitment of the ubiquitin-transferase system. The SOCS box interacts with Elongins B and C, Cullin-5 or Cullin-2, Rbx-1, and E2. Therefore, SOCS-box-containing proteins probably function as E3 ubiquitin ligases and mediate the degradation of proteins associated through their N-terminal regions.
82cd014661555421.062[                     -----                       ]vWA_C3HC4_typeVWA C3HC4-type: Von Willebrand factor type A (vWA) domain was originally found in the blood coagulation protein von Willebrand factor (vWF). Typically, the vWA domain is made up of approximately 200 amino acid residues folded into a classic a/b para-rossmann type of fold. The vWA domain, since its discovery, has drawn great interest because of its widespread occurrence and its involvement in a wide variety of important cellular functions. These include basal membrane formation, cell migration, cell differentiation, adhesion, haemostasis, signaling, chromosomal stability, malignant transformation and in immune defenses In integrins these domains form heterodimers while in vWF it forms multimers. There are different interaction surfaces of this domain as seen by the various molecules it complexes with. Ligand binding in most cases is mediated by the presence of a metal ion dependent adhesion site termed as the MIDAS motif that is a characteristic feature of most, if not all A domains. Membes of this subgroup belong to Zinc-finger family as they are found fused to RING finger domains. The MIDAS motif is not conserved in all the members of this family. The function of vWA domains however is not known.
