This study presents a comprehensive analysis of TIM (Transport Involved in Metabolism) sequences, focusing on conserved region repeats and predicted transmembrane helices. We utilize multiple sequence alignment and PSI-BLAST to identify regions homologous to known proteins and those unique to our dataset. Findings include a notable similarity to antigenic proteins of the Trophozoite stage of *Plasmodium falciparum*, along with locations of missing active site residues and conserved cysteine in dimer interfaces. This work enhances our understanding of TIM within the *P. falciparum* genome.
