Background

SPRED2 (Sprouty-related protein with an EVH1 domain-2) is a 47-53 kDa member of the SPRED family of regulatory molecules. In human, it is found in keratinocytes, intestinal columnar epithelium, and salivary duct epithelium. It inhibits receptor tyrosine kinase (RTK) signaling by blocking Ras activation of Raf. This is achieved by inducing the lysosomal degradation of RTKs following SPRED2 binding to NBR1. Human SPRED2 is 418 amino acids (aa) in length. It contains an N‑terminal WH1/EVH1 domain that is involved in ERK inhibition (aa 5-122), a central KBD domain that binds to the SCFR (aa 201-257), and a C-terminal Sprouty‑related domain that mediates homodimerization, and heterodimerization with SPRED1 (aa 308-416). SPRED is ubiquitinated, and undergoes phosphorylation on Ser, Thr and Tyr residues. There is one splice variant that shows a six aa substitution for aa 1-9. Over aa 117-297, human SPRED2 shares 84% aa identity with mouse SPRED2.
