Chaetomium thermophilum, a eukaryotic thermophile, is an aspiring organism holding great potential for various biochemical and biotechnological applications. Prerequisite for genetic manipulation is a reliable transformation system for target genes combined with selection markers operating at the high growth temperatures of the fungus. Here, we present a detailed protocol for Chaetomium thermophilum protoplast transformation to allow stable chromosomal integration of constructs into its genome, rendering this eukaryotic thermophile a valuable resource for affinity purification of native thermostable protein complexes, like nuclear pore subcomplexes.
Keywords: Affinity purification; Chaetomium thermophilum; Genetic transformation; Nuclear pore complex (NPC); Thermophile.
