An immediate challenge in the post-genomic era is to assign a biological functions to proteins unraveled by genome analysis. This report is based on studies conducted using Schizo saccharomyces pombe, a simple model organism, and presents various vector systems as tools for high-throughput functional analysis of human genes. We constructed S. pombe expression vectors for efficient cloning of genes via the Gateway system. We modified the pREP and pSLF series vectors, which are widely used for gene expression in S. pombe. The vectors constructed have a uniform backbone of S. pombe autonomously replicating sequence (ARS) elements with different selective markers, namely, $ura4^+$ and Saccharomyces cerevisiae LEU2 complementing leu1. These vectors contain 3 different strengths of the inducible promoter nmt1, which affect the expression levels of the cloned open reading frames (ORFs). Further, target proteins can be fused with an N-terminal or C-terminal tag such as triple hemagglutinin ($3{ imes}$ HA), enhanced green fluorescent protein (EGFP), or Discosoma red fluorescent protein (DsRed). We tested the feasibility of the constructed vectors by using 3 human genes, namely, RABI8, SCC-112, and PTEN. Proper expression of tagged RAB18 was confirmed by western blot analysis. Further, localization of RAB18, SCC112, and PTEN was demonstrated. The constructed vectors can be utilized for high-throughput functional analysis of heterologous genes.
