FUNCTIONAL ANALYSIS

Function of 1pujA or the essential GTPase YlqF

Literature supporting conclusion

ProFunc

From a summary of predicted function from our ProFunc results we can see that the most commonly occurring name term is GTPase, followed by GTP binding.

UniProt

During the ProFunc analysis UniProt was used to perform a multiple sequence alignment on our protein sequence. The top 2 results were both highly conserved as well as also being YlqF proteins. The rest of the 10 proteins listed were all either GTPase or GTP binding proteins. This sequence search supports the literature in its claim that the YlqF protein is required for the late step of 50s ribosomal subunit assembly.

SymAtlas

From the distribution of the human ortholog protein in the human body it is evident that this protein is widely distributed and therefore commonly used. These results are consistent with our claim that 1pujA is a GTPase.

Though the distribution of the mouse ortholog protein is somewhat more scattered than the human ortholog protein it is still relatively common in all major tissues meaning that this is also consistent with our claim that 1pujA is a GTPase.

ProKnow

The ProKnow analysis shows that 1pujA's molecular function is GTP binding and its biological function is small GTPase mediated signal transduction.
