Telomeric ORFS in Candida albicans: Does Mediator Tail Wag the Yeast?

Recent studies of fungal genomes have shown that subtelomeric regions of chromosomes are areas of rapid evolution that facilitate adaptation to novel niches [1]. Several years ago, analysis of the genome of the human pathogenic yeast Candida albicans revealed the presence of a large family of telomeric orfs (TLO genes) [2]. The function of this gene family remained an enigma in C. albicans gene...

Telomeric ORFs (TLOs) in Candida spp. Encode Mediator Subunits That Regulate Distinct Virulence Traits

The TLO genes are a family of telomere-associated ORFs in the fungal pathogens Candida albicans and C. dubliniensis that encode a subunit of the Mediator complex with homology to Med2. The more virulent pathogen C. albicans has 15 copies of the gene whereas the less pathogenic species C. dubliniensis has only two (CdTLO1 and CdTLO2). In this study we used C. dubliniensis as a model to investiga...

Myosin structure: Does the tail wag the dog?

Previous crystal structures of the myosin head have shown two different conformations, postulated to be the beginning and the end of the actomyosin power stroke. A new crystal structure reveals a dramatically different conformation; but how does this conformation fit into the force-generating cycle of actomyosin interactions?

Functional characterization of myosin I tail regions in Candida albicans.

The molecular motor myosin I is required for hyphal growth in the pathogenic yeast Candida albicans. Specific myosin I functions were investigated by a deletion analysis of five neck and tail regions. Hyphal formation requires both the TH1 region and the IQ motifs. The TH2 region is important for optimal hyphal growth. All of the regions, except for the SH3 and acidic (A) regions that were exam...

Codon utilisation in the pathogenic yeast, Candida albicans.

The imperfect fungus, Candida albicans is the major yeast pathogen in humans (1). We have analysed the codon usage in eleven C. albicans gene sequences reported in the EMBL and GenBank databases (Table). The codons are divided into three groups (low, medium and high) based upon their codon usage (Table), and these groups are compared with analogous groups for the highly expressed genes from S. ...
