MRTFA (Myocardin-related transcription factor A) is a protein that switches other genes on and off. The public catalogues list it as a fusion partner, and the evidence so far is association rather than a proven role. Tied to Breast cancer, Skin cancer, Lung cancer and 1 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

Transcription coactivator that associates with the serum response factor (SRF) transcription factor to control expression of genes regulating the cytoskeleton during development, morphogenesis and cell migration. The SRF-MRTFA complex activity responds to Rho GTPase-induced changes in cellular globular actin (G-actin) concentration, thereby coupling cytoskeletal gene expression to cytoskeletal dynamics. MRTFA binds G-actin via its RPEL repeats, regulating activity of the MRTFA-SRF complex. Activity is also regulated by filamentous actin (F-actin) in the nucleus. Location: Cytoplasm; Nucleus (UniProt). Locus 22q13.1-q13.2 (HGNC).
