SF efficient DNA-binding only after heterodimerization with (e.g.) E12 [8];
SF strong cooperation between N- and C-terminal domains for MRF4-specific transcriptional activation [3];
SF phosphorylation at several Ser and Thr by PKA and PKC in vitro and in vivo;

CP myogenic cells.

FF myogenic factor, transcriptional activator [1];
FF activates MyoD and myogenin genes;
FF expression repressed by MyoD or myogenin [1];
FF it is transiently expressed after myogenin, before MyoD, and reappears during late stage of skeletal muscle development [6];
FF during limb bud development, it is expressed just at these late stages;
FF it is suggested to play a role in maintaining the differentiated stage [6];
FF down-regulated by bFGF [9];
