Rhomboid Protease Analysis in Cryptosporidium Parvum Parasite

Three rhomboid proteases (CpRom1, CpRom2, CpRom3) were identified in the Cryptosporidium parvum parasite, with distinct subcellular localizations in sporozoite cells. The study analyzes their phylogenetic origin, structural motifs, and lists 10 candidate substrate proteins. Ilaria Vanni authored this research, made available on figshare in April 2026.

Use Cases

• Compare phylogenetic clustering of CpRom1, CpRom2, and CpRom3 catalytic sites with orthologs from Toxoplasma gondii and Plasmodium falciparum.
• Analyze the subcellular localization patterns of the three rhomboids in sporozoites, such as CpRom1 at the apical complex and posterior pole.
• Investigate the genomic absence of the PARL-like rhomboid gene in intestinal Cryptosporidium species versus its presence in gastric species.
• Identify candidate substrate proteins for C. parvum rhomboids based on similarity to proven apicomplexan substrates and co-localization evidence.

Strengths

• Phylogenetic analysis includes comparisons across multiple Cryptosporidium species and other apicomplexans.
• Provides specific subcellular localization data for three distinct rhomboid proteases in sporozoites.
• Identifies 10 candidate substrate proteins based on established biological criteria.

Limitations

• Dataset is a single 109.2 KB PDF document, not a structured data table for computational analysis.
• No raw experimental data (e.g., sequences, alignment files, microscopy images) is provided alongside the analysis.
• Findings are specific to the Cryptosporidium parvum parasite and its three rhomboids, limiting generalizability.
