The CeABF-1 gene. (A) Genomic map position of the CeABF-1 gene. (B) A comparison of the bHLH domains of the ABF-1 regulatory genes shows conservation within the dimerization motif. The bHLH domain of C.elegans ABF-1 is compared with the human and mouse homologs. The human ABF-1 has been used as the canonical sequence. A colon indicates amino acid identities whereas the dash indicates the introduction of a gap into the sequence to maximize amino acid alignment; differences are indicated. Sources for protein sequences are as follows: for human ABF-1 (7) and for mouse musculin/MyoR (9,10).
