SH2 domain containing 3C, also known as SH2D3C, is a protein that in humans is encoded by the SH2D3C gene. [5]
Sh2d3c is a gene on human chromosome 9 that encodes an SH2 domain containing protein known as NSP3. The mouse homologue is found on chromosome 2. The NSP (Novel SH2-containing Protein) family of proteins contains three members, NSP1, NSP2, and NSP3 (this protein), all of which have a similar architecture, with an N-terminal SH2 domain, a proline serine rich region, which contains consensus sequences for MAP kinase substrates, and a conserved C-terminus, which binds to the Cas family of adapter proteins, and also shows homology to GEF domains.
NSP3 was originally identified by three independent groups of researchers. [6] [7] [8] The mouse homologue of NSP3 has been shown to have two distinct isoforms, generated by alternative splicing, that are expressed in different tissues. The shorter isoform, known as Chat (Cas/Hef1 associated signal transducer) is expressed in brain, lung, heart, kidney, muscle, liver, and intestine, while the larger isoform, known as Chat-H (the "H" is for Hematopoietic), is expressed in spleen, thymus, and lymph nodes. [8] The two isoforms differ only in their N-terminus, which has been shown by one group to be important for membrane localization. [9]
Through its interaction with Hef1, Chat-H, has been shown to be an important regulator of lymphocyte adhesion, acting upstream of Rap1 in the integrin activation pathway. [9]
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.
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.
The Linker for activation of T cells, also known as linker of activated T cells or LAT, is a protein which in humans is encoded by the LAT gene. Alternative splicing results in multiple transcript variants encoding different isoforms.
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.
Cbl is a mammalian gene encoding the protein CBL which is an E3 ubiquitin-protein ligase involved in cell signalling and protein ubiquitination. Mutations to this gene have been implicated in a number of human cancers, particularly acute myeloid leukaemia.
Crk-like protein is a protein that in humans is encoded by the CRKL gene.
Protein tyrosine kinase 2 beta is an enzyme that in humans is encoded by the PTK2B gene.
Rap guanine nucleotide exchange factor 1 is a protein that in humans is encoded by the RAPGEF1 gene.
Breast cancer anti-estrogen resistance protein 1 is a protein that in humans is encoded by the BCAR1 gene.
Neural precursor cell expressed developmentally down-regulated protein 9 (NEDD-9) is a protein that in humans is encoded by the NEDD9 gene. NEDD-9 is also known as enhancer of filamentation 1 (EF1), CRK-associated substrate-related protein (CAS-L), and Cas scaffolding protein family member 2 (CASS2). An important paralog of this gene is BCAR1.
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.
Cytoplasmic protein NCK2 is a protein that in humans is encoded by the NCK2 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.
SH2 domain-containing protein 3A is a protein that in humans is encoded by the SH2D3A gene. The protein may be useful in Western Blots and ELISAs.
