SH2 domain containing 3C, also known as SH2D3C, is a protein that in humans is encoded by the SH2D3C gene. [5]

Function

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]
