产品介绍Myogenin is a muscle-specific transcription factor that can induce myogenesis in a variety of cell types in tissue culture. It is a member of a large family of proteins related by sequence homology, the helix-loop-helix (HLH) proteins. It is essential for the development of functional skeletal muscle. [provided by RefSeq, Jul 2008]

 

Function:

Acts as a transcriptional activator that promotes transcription of muscle-specific target genes and plays a role in muscle differentiation, cell cycle exit and muscle atrophy. Essential for the development of functional embryonic skeletal fiber muscle differentiation. However is dispensable for postnatal skeletal muscle growth; phosphorylation by CAMK2G inhibits its transcriptional activity in respons to muscle activity. Required for the recruitment of the FACT complex to muscle-specific promoter regions, thus promoting gene expression initiation. During terminal myoblast differentiation, plays a role as a strong activator of transcription at loci with an open chromatin structure previously initiated by MYOD1. Together with MYF5 and MYOD1, co-occupies muscle-specific gene promoter core regions during myogenesis. Cooperates also with myocyte-specific enhancer factor MEF2D and BRG1-dependent recruitment of SWI/SNF chromatin-remodeling enzymes to alter chromatin structure at myogenic late gene promoters. Facilitates cell cycle exit during terminal muscle differentiation through the up-regulation of miR-20a expression, which in turn represses genes involved in cell cycle progression. Binds to the E-box containing (E1) promoter region of the miR-20a gene. Plays also a role in preventing reversal of muscle cell differentiation. Contributes to the atrophy-related gene expression in adult denervated muscles. Induces fibroblasts to differentiate into myoblasts.

Subunit:
Homodimer and heterodimer with E12; heterodimerization enhances MYOG DNA-binding and transcriptional activities. Interacts with SMARCA4/BRG1/BAF190A. Interacts (via C-terminus region) with SSRP1 and SUPT16H; the interaction is indicative of an interaction with the FACT complex.

Subcellular Location:
Nucleus. Note=Recruited to late myogenic gene promoter regulatory sequences with SMARCA4/BRG1/BAF190A and SWI/SNF chromatin-remodeling enzymes to promote chromatin-remodeling and transcription initiation in developing embryos.

Post-translational modifications:
Phosphorylated by CAMK2G on threonine and serine amino acids in a muscle activity-dependent manner. Phosphorylation of Thr-87 impairs both DNA-binding and trans-activation functions in contracting muscles.

Similarity:
Contains 1 bHLH (basic helix-loop-helix) domain.

 

MYOG是肌肉中运载氧的蛋白质，由153个氨基酸残基组成，一种小分子蛋白质，含有血红素，和血红蛋白同源，与氧的结合能力介于血红蛋白和细胞色素氧化酶之间，可帮助肌细胞将氧转运到线粒体。 肌细胞生成素在成肌分化过程中起着决定性的作用。在人体骨骼肌的胚胎发育过程中 ,肌细胞生成素伴随成肌过程而呈高水平表达。MYOG主要由肾脏代谢并排泄，当心肌或横纹肌有损伤时，肌红蛋白便释放入血中，血清中的肌红蛋白即可明显升高。
