Myogenic determination factor 1 (MyoD1) is a transcription factor and member of the myogenic regulatory factor (MRF) protein family with a role in muscle differentiation.1,2 It is composed of an unstructured N-terminus, a central basic helix-loop-helix domain with a cysteine/histidine domain located at its N-terminus, and a serine/threonine-rich domain proximal to an unstructured C-terminal tail.2,3 MyoD1 is expressed exclusively in skeletal muscle and localized to the nucleus where it binds E-box sequences found in promoters and enhancer regions of muscle-specific genes to regulate transcription during development or in response to skeletal muscle injury. Cayman’s MyoD1 Rabbit Monoclonal Antibody (Clone RM369) can be used for immunohistochemistry (IHC) and Western blot (WB) applications.
