A dominant-negative form of transcription factor MEF2 inhibits myogenesis.
A hallmark of the MEF2 proteins is their propensity to associate with cell-specific and signal-dependent cofactors.
Activation of slow fiber-specific transcription appears to be mediated by a combinatorial mechanism involving members of the NFAT and MEF2 family of transcriptional regulators.
This polypeptide, CHAMP (cardiac helicase activated by MEF2 protein), bears striking resemblance to a number of other helicase proteins and appears to play a role in RNA processing and transcriptional control in heart muscle.
The activity was most pronounced on promoters containing DNA binding sites for MEF2, a transcription factor important for skeletal muscle differentiation.

The Mb pathway involves signaling of the [Ca.sup.2+] concentration variance from muscle cells being transducted to nuclear factor of activated T cells (NFATc1) and myocyte enhancer factor 2 (MEF2) in the nucleus by activating calcineurin (CaN) or calmodulin- dependent protein kinases (CaMK); this modulates the transcription of downstream genes, including the Mb gene [16,17].
For example, chemical inhibition of Jak2 downregulates the transcription factors myoD and MEF2, and target knockdown of Jak2 by siRNA leads to downregulated myoD and MEF2 target gene transcription [94].

The dataset contains 24 sequences, as well as five motifs (Mef2, Tef, Srf, Sp1, and Myf), which play an important role in muscle regulation.
