FHL3Four and a half LIM domains protein 3 is a protein that in humans is encoded by the FHL3 gene.LIM proteins are defined by the possession of a highly conserved double zinc finger motif called the LIM domain.FunctionFHL3 plays a role in myogenesis, and also stimulates the development of neural crest by enhancing BMP signaling.InteractionsFHL3 has been shown to interact with: CREB1, CTBP2, FHL2, ITGA7 and KLF3.
