Non Catalytic Region Of Tyrosine Kinase Adaptor Protein 1 (NCK1)

The Cytoplasmic protein NCK1 Protein belongs to the adaptor family of proteins.The Nck family has two known members in human cells.(Nck-1/Nckalpha and NcK2/NcKbeta), two in mouse cells(mNckalpha and mNckbeta/Grb4) and one in drosophila( Dock means dreadlocks-ortholog). The two murine gene products exhibits 68% aminoacid identity to one another,with most of the sequence variation being located to the linker regions between the SH3 and SH2 domains, and are 96% identical to their human counterparts. While human nck-1 gene has been localised to the 3q21 locus of chromosome 3,the nck-2 genecan be found on chromosome 2 at the 2q12 locus. The protein encoded by this gene is one of the signaling and transforming proteins containing Src homology 2 and 3 (SH2 and SH3) domains.
