| Description | In humans, E2F6 has 8 exons that span 20881 bp of genomic sequence. It has an ORF of 843 nt. |
| Transcription | There have been 5 mRNA splice variants identified in humans. Transcript variant 1 is the predominant transcript, and it encodes the longest mRNA isoform (a), which is 2342 bp. Transcript variant 2 contains an additional segment (2413 bp mRNA), compared to variant 1, that causes a frameshift leading to an early stop codon. This transcript may function in a regulatory role with no protein translated. The predicted protein (isoform b) is much shorter than isoform a. Transcript variants 2 and 4 encode isoform b. Transcript variant 3 lacks a segment (2287 bp mRNA), compared to variant 1, that causes a frameshift leading to an early stop codon. This transcript may function in a regulatory role with no protein translated. The predicted protein (isoform c) is much shorter than isoform a. Transcript variant 4 contains two additional segments (2546 bp mRNA), compared to variant 1, that cause a frameshift leading to an early stop codon. This transcript may function in a regulatory role with no protein translated. The predicted protein (isoform b) is much shorter than isoform a. Transcript variant 5 contains an additional segment (2475 bp mRNA), compared to variant 1, that causes a frameshift leading to an early stop codon. This transcript may function in a regulatory role with no protein translated. The predicted protein (isoform d) is much shorter than isoform a. |
| Pseudogene | There is an E2F6 pseudogene located on chromosome 22q11.2 (LOC376818) containing 2144 bp of the E2F6 gene with no introns. |

| Description | The predominately expressed isoform is 282 amino acids, and is . The DNA binding domain is thought to be between aa 50 and 129. It has a DEF box between aa 95 to 195. The dimerization domain is thought to reside between aa 130 and 222. There is a leucine zipper domain between aa 143 and 164. The transcriptional repression domain is located on the C terminus from aa 173 to 281. The N-terminal 1-75 aa are missing in isoform B which is predicted to be 206 AA. |
| Expression | Ubiquitous, though more highly expressed in the placenta, skeletal muscle, heart, ovary, kidney, small intestine and spleen. |
| Localisation | Nuclear |
| Function | Heterodimerization with DP1 or 2 creates a sequence specific transcriptional repressor. Overexpression of E2F6 can delay the exit of cells from S-phase, indicating a role for E2F6 in cell-cycle control. E2F6 has been shown via yeast two hybrid and co-IPs to interact with members of the polycomb repressive complex 1, such as Bmi1, RYBP, RING1, MEL-18, and Mph1. The functional outcome of these interactions are as of yet unclear. E2F6 has been biochemically purified in a complex containing polycomb group members h-1(3) mbt like protein, RING1, RING2, hMBLR, as well as YAF and HP1g; this complex also contained a novel euchromatic histone methyltransferase (Eu-HMTase1). This finding led to speculation that E2F6 controlled cellular entry into quiescence, but E2F6 nullizygous MEFs had no kinetic changes or defects in their ability to enter quiescence, or to re-enter into the cell-cycle. However, these animals had homeotic transformations of the axial skeleton, a phenotype that resembled Bmi1 nullizygous mice. This implicated E2F6 in regulation of normal development. |
| Homology | E2F6 has homology with E2Fs1-5 in the DNA-binding domain, the dimerization domain, and the marked box domain located between aa 231 and 239. |
