Rabbit Anti-phospho-MYF5 (phospho Ser49)/FITC Conjugated antibody
background:
Differentiation of myogenic cells is regulated by multiple positively and negatively acting factors. One well characterized family of helix-loop-helix (HLH) proteins known to play an important role in the regulation of muscle cell development include Myo D, myogenin, Myf-5 and Myf-6 (also designated MRF-4 or herculin). Of interest, most muscle cells express either Myo D or Myf-5 in the committed state, but when induced to differentiate, all turn on expression of myogenin. Myo D transcription factors form heterodimers with products of a more widely expressed family of bHLH genes, the E family, which consists of at least three distinct genes: E2A, IF2 and HEB. Myo D-E heterodimers bind avidly to consensus (CANNTG) E box target sites that are functionally important elements in the upstream regulatory sequences of many muscle-specific terminal differentiation genes.
Function:
Involved in muscle differentiation (myogenic factor). Induces fibroblasts to differentiate into myoblasts. Probable sequence specific DNA-binding protein.
Subunit:
Efficient DNA binding requires dimerization with another bHLH protein.
Subcellular Location:
Nucleus.
Similarity:
Contains 1 bHLH (basic helix-loop-helix) domain.

yf5是MyoD基因家族的一员,该家族的共同结构特点是具有1个保守的中央蛋白基序(motif),大小为80个氨基酸,称为碱性螺旋-环-螺旋(bHLH),bHLH高度保守,其中Basic结构是HLH螺旋结构的延伸,也是这一家族蛋白与DNA相互作用的区域,而HLH螺旋结构则是与其他因子相互作用的位点,即调控的重要区域。
生肌决定因子(MyoD)基因家族控制着肌细胞的增殖和分化,与肌纤维的数量、大小有着密切的关系,因而对肉质和风味有非常重要的作用,MyoD基因家族可编码4种不同的转录因子,分别为MyoD(Myf3)、Myogenin(MyoG)、Myf5、Myf6或MRF4,它们各自或协同控制着骨骼肌生成方面的关键调节因子。
