Trichophyton verrucosum is a zoophilic dermatophyte, which causes
dermatophytosis infection in human as well as animals. 26S
proteasome is an important protein in eukaryotic cells that
is involved with
degradation of unneeded or damaged
proteins, when tagged with ubiquitin. In this study, we characterized the 26S Proteasome regulatory subunit
gene in dermatophyte pathogen T. verrucosum. High
molecular weight DNA has been isolated from T. verrucosum
and utilized with pairs of specific nucleotides primers,
designed from highly preserved regions of the 26S proteasome
regulatory subunit genes. Obtained DNA fragments were
sequenced and the results were analyzed in GenBank. This DNA
fragment, which contains no intron within its open reading
frame, encodes a polypeptide with 332 amino acids. The
characterized PCR fragments revealed significant homology
with other 26S proteasome regulatory subunit genes in
GenBank.
