    motifs/domains
  • three SH3 domains
  • a unique SH2 domain that recognizes a specific phosphotyrosine residue on RTKS or on substrates of RTKS like IRS1, lacking a catalytic domain
  • a previously unrecognized activation motif in a linker between the first two SH3 domains, and this linker sequence, reminiscent of bacterial virulence factors, di26554011)rectly engages the WASL GTPase binding domain (GBD) and competes with verprolin-homology, connector-helix, acidic motif (VCA) binding

    basic FUNCTION
  • adaptor protein involved in transducing signals from receptor tyrosine kinases to downstream signal recipients such as RAS
  • intracellular adaptor protein that is involved in actin polymerization
  • independent roles and mechanisms of action of NCK1 and NCK2 in dermal fibroblast migration, which is critical for wound healing
  • endogenous regulator of PKR and NCK1-PKR interaction could be a way to limit PKR activation
  • NCK1 is the regulator of RASA1 activity
  • proteasomal regulation is a key factor in the distinct and non-redundant effects of NCK1 on RHOA-mediated actin dynamics
  • NCK1 and NCK2 have non-redundant roles in human T cell activation
  • role for NCK1 in regulating gene expression through its role as the scaffold for assembly of the cytoplasmic capping complex
  • crucial role for NCK1 as a master regulator within the endothelium to control actin cytoskeleton organization, vascular network remodeling, and endothelial-to-mesenchymal transition (EnMT) during cardiovascular development
  • regulates preosteoblastic/osteoblastic migration and bone mass

    LCP2/GRAP2/NCK1 adaptor protein pathway, implicated in regulation of the actin cytoskeleton by BCR-ABL kinase
    a component
  • FYB/NCK1 complex might provide a means to link integrin activation with the actin cytoskeleton
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • associates with BLNK, PCLG1, VAV1 and NCK1 in a B-cell antigen receptor-dependent fashion
  • strong binding of CD3epsilon to EPS8L1 and NCK1 SH3 domains
  • connection between septins, SOCS7, NCK1/NCK2 signaling, and the DNA damage response
  • in podocytes, links the slit-diaphragm protein nephrin to the actin cytoskeleton (interaction essential for nephrin-dependent reorganization of actin in podocyte injury)
  • connect PDGF-BB signaling to the actin cytoskeleton and cell motility
  • interaction with SORBS1 (implications for a role in cytoskeletal remodelling during differentiation of skeletal muscle cells)
  • functional cooperation between NCK1 and FYB mediates LCP2/WAS interactions and actin rearrangement
  • directly binds and activates the GTPase-activating protein of RAS (RASA1), which is responsible for the down-regulation of RAS
  • NCK1 interacts with PTPN1 and the NCK1/PTPN1 complex inducibly associates with the IR for the attenuation of IR activation in mammalian cells
  • LRFN4 complexed with SFN and NCK1 to mediate elongation in monocytic cells via RAC-1-mediated actin cytoskeleton reorganization
  • NCK1 directly modulates NPHS1 phosphorylation through formation of a signaling complex with the Src family kinase FYN
  • NCK1 recruitment to the TCR required for ZAP70 activation during thymic development
  • WIPF1 acts as an essential link between NCK1 and WASL
  • adaptor function for NCK1 in recruiting PK3AP1 to sites of BCR signaling
  • ITSN1 is an important general regulator of CDC42-, NCK1- and WASL-dependent actin polymerisation
  • NCK1 recruitment to the TCR is fundamental to mount an efficient T cell response, and the NCK1-CD3E interaction may represent a target for pharmacological modulation of the immune response
  • NCK1-ELMO1 interaction promoting RAC1 activation and cell motility
  • interacts with PTPN1 and also regulates PTPN1 expression, playing a role in regulating the PI3K/AKT1 pathway
  • NCK1 was the most potent activator of WASL-driven actin assembly
  • NCK1 integrates NPHS1 with the Hippo kinase cascade through association with the adaptor protein WTIP
