OnCo

TMSB4X (Thymosin beta-4) is a gene whose normal job is to hold cell growth in check. 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 Non-Hodgkin lymphoma and Diffuse large B-cell lymphoma. 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

Plays an important role in the organisation of the cytoskeleton. Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerisation. Potent inhibitor of bone marrow derived stem cell differentiation. Acts by inhibits the entry of haematopoietic pluripotent stem cells into the S-phase. Location: Cytoplasm, cytoskeleton (UniProt). Locus Xp22.2 (HGNC).
