NSP1 is a cytoplasmic signaling intermediate that functions as an adaptor or scaffolding protein to integrate growth factor receptor and integrin signals. The protein contain an N-terminal SH2 domain, a central proline:serine-rich region, and a C-terminal sequence. The protein is phosphorylated in response to insulin and EGF (and insulin-like growth factor I and heregulin) indicating that NSP1 is a common target for a variety of growth factor receptors. The protein is thus involved in a process by which receptor tyrosine kinase and integrin receptors control the c-Jun N-terminal kinase:stress-activated protein kinase pathway. Protein expression is usually restricted to tissues with secretory epithelial cells. The gene encoding for human NSP1 is localized in the chromosomal region 19p13.3.
