- Abstract
The single human gene for muscle-specific enolase was isolated and its structure was characterized, from which the mature mRNA transcript and encoded protein were also deduced. The gene contains 12 exons, spans approx. 6 kb and encodes a protein of 433 residues. The gene structure is similar to that found for the rat neuron-specific enolase gene, and the deduced protein aligns precisely with other enolase sequences, including the sequence of the only published crystallized enolase, yeast eno-1. The 5' boundary of the gene includes a 5' non-coding exon and is characterized by an upstream TATA-like box and CpG-rich region. This region contains potential recognition motifs for general transcriptional regulation involving Sp1, activator protein 1 and 2, CCAAT box transcription factor/nuclear factor I and cyclic AMP, and for muscle-specific transcriptional regulation involving a CC(A + T-rich)6GG box, M-CAT-box CAATCCT and two myocyte-specific enhancer-binding factor 1 boxes.
