Cytoplasmic protein NCK2 (also known as NCK-beta and Grb4) is a protein that in humans is encoded by the NCK2 gene. [5] [6] [7]
NCK belongs to family of adaptor proteins. There are two mammalian NCK genes, NCK1 and NCK2. NCK1 is located in chromosome 3 and NCK2 is located in chromosome 2. The protein contains three SH3 domains and one SH2 domain. The protein has no known catalytic function but has been shown to bind and recruit various proteins involved in the regulation of receptor protein tyrosine kinases. It is through these regulatory activities that this protein is believed to be involved in cytoskeletal reorganization. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [7]
NCK2 has been shown to interact with:
The epidermal growth factor receptor is a transmembrane protein that is a receptor for members of the epidermal growth factor family of extracellular protein ligands.
Growth factor receptor-bound protein 7, also known as GRB7, is a protein that in humans is encoded by the GRB7 gene.
Growth factor receptor-bound protein 2 also known as Grb2 is an adaptor protein involved in signal transduction/cell communication. In humans, the GRB2 protein is encoded by the GRB2 gene.
Son of sevenless homolog 1 is a protein that in humans is encoded by the SOS1 gene.
Adapter molecule crk also known as proto-oncogene c-Crk is a protein that in humans is encoded by the CRK gene.
Integrin-linked kinase is an enzyme that in humans is encoded by the ILK gene involved with integrin-mediated signal transduction. Mutations in ILK are associated with cardiomyopathies. It is a 59kDa protein originally identified in a yeast-two hybrid screen with integrin β1 as the bait protein. Since its discovery, ILK has been associated with multiple cellular functions including cell migration, proliferation, and adhesion.
Lymphocyte cytosolic protein 2, also known as LCP2 or SLP-76, is a signal-transducing adaptor protein expressed in T cells and myeloid cells and is important in the signaling of T-cell receptors (TCRs). As an adaptor protein, SLP-76 does not have catalytic functions, primarily binding other signaling proteins to form larger signaling complexes. It is a key component of the signaling pathways of receptors with immunoreceptor tyrosine-based activation motifs (ITAMs) such as T-cell receptors, its precursors, and receptors for the Fc regions of certain antibodies. SLP-76 is expressed in T-cells and related lymphocytes like natural killer cells.
GRB2-associated-binding protein 2 also known as GAB2 is a protein that in humans is encoded by the GAB2 gene.
PTK2 protein tyrosine kinase 2 (PTK2), also known as focal adhesion kinase (FAK), is a protein that, in humans, is encoded by the PTK2 gene. PTK2 is a focal adhesion-associated protein kinase involved in cellular adhesion and spreading processes. It has been shown that when FAK was blocked, breast cancer cells became less metastatic due to decreased mobility.
Serine/threonine-protein kinase PAK 1 is an enzyme that in humans is encoded by the PAK1 gene.
Crk-like protein is a protein that in humans is encoded by the CRKL gene.
Rap guanine nucleotide exchange factor 1 is a protein that in humans is encoded by the RAPGEF1 gene.
Cytoplasmic protein NCK1 is a protein that in humans is encoded by the NCK1 gene.
The B-cell linker protein is encoded by the BLNK gene and is an adaptor protein also known as SLP-65, BASH, and BCA. BLNK is expressed in B cells and macrophages and plays a large role in B cell receptor signalling, in a fashion analogous to the role its paralogue SLP-76 plays in T cell receptor signalling. As it has no known intrinsic enzymatic activity, the function of BLNK is to temporally and spatially coordinate and regulate signalling effectors downstream of the B cell receptor.
GRB2-related adapter protein 2 also known as GRB2-related adaptor downstream of Shc (GADS) is a 37 kDa protein that in humans is encoded by the GRAP2 gene.
Serine/threonine-protein kinase N2 is an enzyme that in humans and Strongylocentrotus purpuratus is encoded by the PKN2 gene.
LIM and senescent cell antigen-like-containing domain protein 1 is a protein that in humans is encoded by the LIMS1 gene.
Src kinase-associated phosphoprotein 1 is an adapter protein that in humans is encoded by the SKAP1 gene.
SH2 domain containing 3C, also known as SH2D3C, is a protein that in humans is encoded by the SH2D3C gene.
SH2B adapter protein 3 (SH2B3), also known as lymphocyte adapter protein (LNK), is a protein that in humans is encoded by the SH2B3 gene on chromosome 12.
