 TI    The mating-type region of Schizosaccharomyces pombe contains an
       essential gene encoding a protein homologous to human modulators of HIV
       transactivation.

 AB    In Schizosaccharomyces pombe, an intrachromosomal crossover between the
       mating type (MT) expression locus and one of the silent donor cassettes
       is lethal due to the loss of the intervening L region. The region
       contains one essential gene, let1. This gene was cloned and sequenced.
       The deduced amino acid (aa) sequence of let1 shows extensive homologies
       with SUG1 from Saccharomyces cerevisiae. Significant homologies were
       also found with the human HIV transactivation modulators, MSS1 and
       TBP-1, as well as with subunit 4 of the mammalian 26 S protease. The
       data indicate that let1 is a member of a recently defined multigene
       family of ATPases.
