TV44 amino acid sequence alignment with proteins of BLAST search. The corresponding proteins of Entamoeba histolytica [XM 645307.1], Saccharomyces cerevisiae [P 53040], Arabidopsis thaliana [AY463621.1], Homo sapiens [AAH18115], and Candida albicans [XM 711022.1] were aligned by the Clustal W program. The conserved residues are indicated by black shading, and similarity is indicated by grey shading. TV44 had partial homology to transcription initiation factor (TFIID) of E. histolytica (13% identity) and S. cerevisiae (16%). TV44 had homology to the TATA-binding protein associated factor of A. thaliana (15%) and H. sapiens (13%) and, in addition, to the RNA pol II transcription factor of C. albicans (17%).
