| Description | 7 exons; about 10 kb |
| Transcription | complex; alternative splicing: two donor sites in exon 1; transcripts A, the most abondant, ubiquitous: splicing from exon 1 to exon 6; transcripts B, rare: splicing from exon 1 to exon 2; initiation of the transcription: an alternative site of initiation of the transcription in intron 1 has been found in one tumor with a translocation breakpoint in intron 1 |
