OnCo

SPEN (Msx2-interacting protein) is a protein that switches other genes on and off. The public catalogues list it as an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Breast cancer, Non-Hodgkin lymphoma, Renal cell carcinoma and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

May serve as a nuclear matrix platform that organises and integrates transcriptional responses. In osteoblasts, supports transcription activation: synergises with RUNX2 to enhance FGFR2-mediated activation of the osteocalcin FGF-responsive element (OCFRE). Has also been shown to be an essential corepressor protein, which probably regulates different key pathways such as the Notch pathway. Negative regulator of the Notch pathway via its interaction with RBPSUH, which prevents the association between NOTCH1 and RBPSUH, and therefore suppresses the transactivation activity of Notch signalling. Blocks the differentiation of precursor B-cells into marginal zone B-cells. Probably represses transcription via the recruitment of large complexes containing histone deacetylase proteins. Location: Nucleus (UniProt). Locus 1p36.21-p36.13 (HGNC).
