3.6.5.2 | malfunction | RNAi knockdown of Trypanosom brucei Arl6 results in shortening of the trypanosome flagellum without loss of motility | Trypanosoma brucei |
3.6.5.2 | additional information | structure analysis and comparison of trypanosomal and human Arl6/BBS3 proteins, overview. Analysis of the TbArl6 active site confirms that it lacks the key glutamine that activates the nucleophile during GTP hydrolysis in other small GTPases. The trypanosomal proteins are significantly shorter at their N-termini suggesting a different method of membrane insertion compared to humans. Two surface patches may be important for protein-protein interactions | Trypanosoma brucei |
