Description_x000D_ General description_x000D_ Members of the SPEN (Split-end) family of proteins, including RBM15, have repressor function in several signaling pathways and may bind to RNA through interaction with spliceosome components (Hiriart et al., 2005 [PubMed 16129689]).[supplied by OMIM_x000D_ Immunogen_x000D_ RBM15 (NP_073605.4, 701 a.a. ~ 810 a.a) partial recombinant protein with GST tag.

It plays a vital role in the NXF (Nuclear export factor) pathway. It directly binds to NXF1 and provides receptor for the RNA export element RTE. This conjugated form helps to enhance RTE-mediated expression. RBM15 has the ability to identify specific RTE RNA in vitro, which finally enhances export and expression of RTE-containing reporter mRNAs in vivo.
