FHL3 contains 4 LIM zinc-binding domains. It is expressed only in skeletal muscle. FHL3 association with MyoD may contribute to the regulation of MyoD-dependent transcription of muscle genes and thereby myogenesis.LIM proteins are defined by the possession of a highly conserved double zinc finger motif called the LIM domain.[supplied by OMIM].
