Protein attributes
| Sequence length | 682 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Transcriptional regulator. Involved in the initiation of neuronal differentiation. Activates transcription by binding to the E box (5'-CANNTG-3'). |
| Subunit structure | Efficient DNA binding requires dimerization with another bHLH protein. Forms homo- or heterooligomers with myogenin, E12 and ITF2 proteins. Interacts with PTF1A. Interacts with NEUROD2 By similarity. Interacts with RUNX1T1. Ref.9 Ref.18 |
| Subcellular location | |
| Tissue specificity | Expressed in several tissues and cell types including skeletal muscle, thymus, and a B-cell line. |
| Domain | the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors. Ref.11 |
| Sequence similarities | Contains 1 bHLH (basic helix-loop-helix) domain. |
