Analysis of protein function in clinical C. albicans isolates.

ABSTRACT: Clinical isolates are prototrophic and hence are not amenable to genetic manipulation using nutritional markers. Here we describe a new set of plasmids carrying the NAT1 (nourseothricin) drug resistance marker (Shen et al., ), which can be used both in clinical isolates and in laboratory strains. We constructed novel plasmids containing HA-NAT1 or MYC-NAT1 cassettes to facilitate PCR-mediated construction of strains with C-terminal epitope-tagged proteins and a NAT1-pMet3-GFP plasmid to enable conditional expression of proteins with or without the green fluorescent protein fused at the N-terminus. Furthermore, for proteins that require both the endogenous N- and C-termini for function, we have constructed a GF-NAT1-FP cassette carrying truncated alleles that facilitate insertion of an inta
